High Knob is a special place because its
more than just a mountain peak.

MUCH more!

Early October 2006
Looking Across The High Knob Landform
Photograph by Dan Weemhoff - © All Rights Reserved.

The peak known as High Knob caps a remnant massif ( large mountain mass ) that is part of an extraordinarily diverse mountain landform, the High Knob Landform ( HKL ).

The High Knob Massif is the remnant highcountry of the HKL.  It extends from majestic Guest River Gorge southwestward to the Duffield Valley, to include its rugged northwestern arm called Little Stone Mountain.

Powell Valley Inside of High Knob Massif

In between Little Stone Mountain and the core of the remnant massif lies a arrowhead-shaped valley, the majestic Powell Valley of Wise County, Va., which marks the end of a great erosional breach in the HKL that continues southwestward as the beautifully rolling valleys of Lee County, Va., past historic and famous Cumberland Gap to Norris Lake and the I-75 corridor of northern Tennessee.

From a geological perspective, majestic Powell Valley of Wise County marks the ending of the great erosional breachment of the High Knob Landform which formed via headward erosion over time toward the northeast.

The northwestern mountain flank of the HKL is especially rugged and distinct with extraordinary natural features such as Cumberland Gap National Historical Park, Cave Springs Wilderness Area, and Roaring Branch Gorge ( to note only a few ).

When you stand upon lofty High Knob you are standing on a landform whose roots extend downward for several miles beneath your feet and whose surface spreads outward across ten counties and three states.

It is much, MUCH, more
than a mere knob!

But what truly makes the HKL special is that its landform possesses endemic characteristics on many major levels of the natural sciences. This is the realization that must be learned in order to truly appreciate this great mountain landscape, since it's loss due to ignorance for what it is would be one of the greatest tragedies in the history of Virginia and the United States.

This is not a landform made
for resource extractions.

It is the fresh water giver, clean air maker,
and major weather changer of this region.

The High Knob Landform
A great continuous mountain landform
consisting of:

1 ). a remnant massif of highcountry

2 ). a northwestern mountain flank

3 ). a southeastern mountain flank

4 ). an eroded calcareous core that separates these mountain flanks and narrows by headward erosion, to the northeast, into the inverted V-shaped Powell Valley ( adjacent to the High Knob peak ).

Endemic Characteristics of
The High Knob Landform


Geology

Wayne Browning - © All Rights Reserved.

*The HKL is the most dominant structural feature of the 3125 square mile Cumberland Mountain Overthrust Block, the largest piece of deformed continental crust of its kind exposed in the Appalachians
( also called the Pine Mountain Thrust Sheet ).

The Cumberland Overthrust Block is the northwestern-most major thrust sheet in the great southern Appalachian fold-thrust belt and is considered to be the classic model for mountain building ( orogenic ) processes of folding and thrust faulting associated with
"thin-skinned" tectonics.

*The breached Powell Valley Anticline of the HKL is the only geological structure in Virginia ( and known in the Appalachians )
to host caves in all major cave bearing stratas from
Cambrian through Mississippian age.

The Powell Valley Anticline is the structural foundation, and support for the High Knob Landform.  However, as noted in my extensive follow-up comments at the end of this section,
the HKL is much more than just a geological structure.

*Embedded within the northwestern mountain flank of the
High Knob Landform, adjacent to Fern Lake and Cumberland Gap National Historical Park, is the unique circular basin in which lies Middlesboro, Kentucky. This is widely felt to be an astrobleme.

*From base to base the High Knob Massif ( remnant highcountry of the HKL ) is the widest single mountain mass in all of western Virginia, and one of the widest in the Appalachians.

*The High Knob Massif contains the highest upper elevation basins in the entire 150+ air mile expanse of the Cumberland Mountains ( valleys at 2400 to 3600 feet above sea level ).

*The High Knob Massif contains the longest backslope 
( distance from its S-SE base to N-NW crestline that is not associated with a ridge or spur ) of any mountain in western Virginia and the Cumberland Mountains.

*The High Knob Massif  and its NW arm contain one of the greatest concentrations of mountain gorges of any singular mountain mass in the southern Appalachians ( a result of its large size and amazing structural geology ).

Many other cultural and physical features are present along this truly awesome and magnificent mountain flank.

An increasingly wide and majestic karst valley of rolling ridges and open expanses becomes a dominant topographic feature of the landform ( eroded calcareous core of the ancient High Knob ) southeast of its NW Flank and southwest of its remnant massif.

Discussion Of Above Image

This image illustrates how BIG the remnant massif of High Knob is as snow, the white on this image, covers most of its elevated high country except for portions of its northwest, northern & extreme southeast bases ( via a significant snow, ice & rime event in December 2002 with a SE air flow component that upsloped across the massif ).

Note how wide the white area is across the High Knob Massif compared with that capping the adjacent crestlines of Black Mountain, along the Virginia-Kentucky border to the west, and Clinch Mountain to the southeast.  

Pine Mountain can be seen farther northwest, stretching southwest from Breaks Gorge on the VA-KY border across SE Kentucky ( with variable amounts of snow cover along its length ).

Observe how The Cedars of Lee County, Va., show up beautifully amid the breached calcareous core of the HKL as the elongated dark green strip eastward of the V-notch appearing white sections marking snow that is capping Cumberland & Brush mountains of Cumberland Gap NHP on the above map ( Martins Fork Basin being less well covered and illuminated by snow in between the high mountain crestlines, to create a darker section amid the V-shaped whiteness laying across northeastern sections of the National Park ).

A more general covering of snow is observed north of the massif, across central-northern Wise County and the northwest portion of Dickenson County in Virginia.  Note the MANY mountain ridges and hills across this area, and to the west of Pine Mountain, and how small they appear in comparison to the High Knob Massif.

The High Knob Landform ( HKL ) is HUGE, of course, and its remnant massif is very large.  In fact, the highcountry of the remnant massif of High Knob is larger than some counties in eastern Virginia and the state of Kentucky!

*Upper elevations of the High Knob Massif contain types of Northern Hardwood and High Elevation Cove Forest communities that are endemic to the southern Appalachians
( and very rare amid the Cumberland Mountains ).

Lower Elevations are Below 2000 feet
Middle Elevations are 2000 to 3000 feet
Upper Elevations are Above 3000 feet

( Elevations in feet above mean sea level )

The High Knob Massif contains more than 
100 square miles above 2400 feet and around 
50 square miles above 3000 feet.

During the 1990's The Nature Conservancy named this amazingly diverse mountain region as:

"One Of The Last Great Places On Earth."

A great summary for The Upper Tennessee River Basin section is presented in the following video by my friend and acclaimed naturalist Richard Kretz:

This is a mountain region of dramatic seasonal weather changes with amazing transformations between Autumn, Winter, Spring, and Summer that impact all aspects of its natural world.

These seasonal weather variations are enhanced in the High Knob Massif where higher elevations, atypically wide base to base widths, and excellent air flow exposures work to make it the wettest area in Virginia ( High Knob Massif - Black Mountain being the wettest in both Virginia & Kentucky over the longer term ).

A Few Specific Climate Features
of The High Knob Landform ( HKL )

*The HKL generates an orographically enhanced upslope flow on southwesterly airflow trajectories that is unique to Virginia, and the southern-central Appalachians, in its enhancement of both rainfall and snowfall ( especially strong in the orographic forcing season of November-May across the 
High Knob Massif ).

An analogous enhancement occurs on rainfall across southern portions of the Appalachian chain, and along outward projecting portions of the Virginia Blue Ridge, but rarely ever includes significant snowfall like occurs in the High Knob Massif area.

*The High Knob Massif generates a major enhancement of precipitation on southeasterly 
air flow trajectories during the cold season, under specific conditions, that appears to be indigenous to the massif ( thermally indirect mesoscale or TIM circulation ).

Thermally Indirect Mesoscale ( TIM ) Circulation:

*The City of Norton is the wettest town or city in Virginia on an annual basis ( over decades ) as verified by data scans at the UVA Climatology Office in Charlottesville, the Southeastern Regional Climate Center, and the North Carolina State Climate Office's Regional Database.

This is due to Norton's location within the orographic lifting zone of the High Knob Massif, and to the other unique weather features forced by the atypically wide base to base expanse of the massif.

Another notable cold season aspect is the number of days with 1" or more of snow depth, with a mean of 83 days observed during the 8 winter seasons from 2003-04 to 2010-11 across northern slopes of High Knob Lake Basin
( mean of 11.9 weeks per season ).

*The High Knob Massif generates distinct snow shadows that change with variations in wind direction ( unique for a mountain of its height with the major forcing of this being again related to its atypically large base to base widths and excellent exposures to air flow of varying trajectories ).

It is common for huge snow depth differences to develop during
the cold season between the remnant highcountry of the High Knob Landform and locations leeward ( downstream ) of its sprawling massif and rugged northwestern mountain flank ( this being aided by the Black mountains and Pine Mountain for NW air flow trajectories ).

This shadowing effect contributes to the Tri-Cities of NE Tennessee getting 5 to 15 FEET less snow than the High Knob Massif during any given winter season!

It is also common for large snow depth differences to develop each winter between the High Knob Massif and its calcareous heart
( e.g., Powell Valley & Powell River Valley ).

( 4"-diameter NWS rain gauge ).

*The 6.31" monthly mean for 41 consecutive months measured at Big Cherry Dam of the 
High Knob Massif is the highest ever observed 
in Virginia over such an extended period of time
( November 2008 to March 2012 ) despite up to 3.50" or more of loss per year due to evaporation between hand-measurements and falls of snow 
too deep for the rain gauge to physically hold.

For a few examples please reference the following:

*The High Knob Landform helps force an atypical decrease in annual precipitation amounts traveling UP Basin in the Clinch River watershed on air flows with mean SW components.

Annual Precipitation Difference from Norton to Lebanon

14-Year Annual Mean ( 1990-2003 )

City of Norton: 58.54"

Town of Lebanon: 42.96"
( -15.58" less per year in Lebanon )

Long-term differences are simply amazing as exemplified by Burkes Garden sitting upon the Tennessee Valley Divide at the head of the Clinch River Basin, where despite its high elevation and long record period ( 1896-Present ) there has been only one year ( January-December period ) with more than 60.00" 
of total precipitation ( 63.02" in 1972 ).

Differences verses upper elevations are even greater between 
the High Knob Massif and head of the Clinch River Basin.

While Big Cherry Dam and Burkes Garden measuring sites are close to the same elevation, 
Big Cherry Dam averaged 24.70" more per year than Burkes Garden during the 2009-2011 period 
( despite significant precipitation losses totaling up to 3.50"+ 
per year at Big Cherry Dam that were not included ).

Burkes Garden
2009-2011 Precipitation Totals

2009: 54.68"
2010: 47.73"
2011: 50.69"

3-Year Mean: 51.03" ( M )*

( M )* - Indicates 2 missing days during December 2010.

[ Precipitation is hand-measured daily in Burkes Garden with a 
8"-diameter NWS rain gauge and once every 7 days on average 
at Big Cherry Dam ( 4"-diameter NWS rain gauge ) ].


*The HKL is a verified and prolific generator of orographic cloud forms above ground, and is likely the most prolific "internal" cloud generator in Virginia ( and perhaps, the Appalachians ).

Rime deposition on trees and fog drip from trees are major secondary moisture sources in the High Knob Landform with upslope flow across its mountain flanks & remnant massif, as well as cold air drainage from its high terrain, being key to condensing moisture out of the air for extraction by vegetation.

This often gives travelers of the famed "Crooked Road" a visual treat along what is by many accounts the most scenic section of the
Country Music Highway ( U.S. Route 23 ).

Wetlands are extremely important in the 
High Knob Massif since they:

1 ).  Increase the diversity of LIFE

2 ).  Clean water before it enters 
lakes & streams

3 ).  Reduce & slow down flash flooding
plus do MANY other things important to all life
( including YOURS )!

4 ).  *Are Frost Pockets from which cold air drains into and from throughout the year.

*Cold air pools in these high valleys and eventually drains from them to generate and enhance significant cold air drainage corridors in the High Knob Massif that feature Mixed-Mesophytic Northern Hardwoods which finger downward from endemic Southern Appalachian Northern Woods ( at elevations above 3300-3600 feet ).

The southwestern end of the High Knob Massif is formed by rugged Cliff Mountain, of the Powell Mountain Block, which towers more than 2000 vertical feet above 
"The Divide" and North Fork of the Clinch River Gap.

At least a couple of ponds ( man-made or natural ) rest high upon the mountain, with one in particular being large and apparently within a natural depression that shows no signs of recent disturbances by man.
Very interesting and beautiful.

*The High Knob Massif can handle more total precipitation without flooding ( rainfall and/or rain + snow melt ) than other locations across western Virginia since most creeks draining its highcountry sink, or partially sink, into the subterranean prior to reaching regional base levels marked by the ecologically renowned Clinch and Powell rivers.

Karst Landscape of High Knob Landform

Since much of the highcountry of the massif is upheld by more resistant stratigraphy, such as quartzarenites, it hides the fact that it is largely a karst landscape with hydrologically complex conduit systems. This being especially true since the High Knob Landform possesses a form of scarp-slope karst that gives little evidence of its presence on the surface ( relative to its calcareous valleys ).

*Drainage from the High Knob Massif has been responsible for formation of the famed Natural Tunnel, amid The Natural Tunnel State Park, and the hydrologically complex conduit system of the Rye Cove Karst Basin ( the largest karst cove in Virginia ).

When combining all the photographs in this section with all the different groups of information nothing can deny that this is a great, continuous mountain landform!

Whether it be called the High Knob Landform, Powell Valley Anticline, or simply by the multitude of individial local names for different sections it is important that it be recognized as a continuous, consolidated, landscape of an ancient mountain landform.  Only then does its true greatness and significance become realized for all to see!

Follow-Up Comments By Author:
Why Is It Important To Recognize The HKL?

There are countless reasons to recognize the High Knob Landform ( HKL ) and NOT one has to do with myself being the first to ever name it in such a way ( since the name High Knob was given LONG before I was born ) or the first to document it by bringing together major natural sciences to form a single picture!


Some geologists may say that the HKL is nothing more than the great Powell Valley Anticline, which has been recognized as a geological structure since at least the 1920s and 1930s
( by famous geologists Chester Wentworth, Charles Butts,
and John Rich ).

However, the HKL is MUCH
more than just a geologic structure! 

Photographs used throughout this introduction and website are illustrating that for everyone to see with their own eyes.

To say that the High Knob Landform ( HKL ) ONLY equals the Powell Valley Anticline would be analogous to saying that the skeleton alone is equal to the human body.

The skeletal system of the body has no life, no functional use, without the brain, heart, lungs, and all the other organs, muscles, ligaments, tendons, and skin completing the human system!

In the same way, all of these organs and tissues can not function as a unit without a skeletal system to give them structural support. 

The two can not be separated.

In like manner, the Powell Valley Anticline can not be separated from the High Knob Landform since it functions as the HKL's structural support. 

The HKL would simply not exist as the incredible landform it is without the structural framework which holds it all together. 

There is no doubt about that.

However, this structural framework alone, by itself, is not the HKL.

The HKL is the combination & resultant product of an infinite, amazing, assemblege of natural forces working together over a truly great vastness of time, which encompasses more than just its structural framework as defined by geology. 

The capabilities, limited as they may be, of the natural sciences of today allow us as scientists to study the products of the intimate and very highly interconnected workings of all these grand natural forces ( allowing, at least, for the generation of a BIG picture ).

Just like the human body can not be adequately described by highlighting only it's skeleton, or heart, so the HKL can not be justly defined, understood, or described without bringing together ALL of the major natural sciences which outline its domain.

And make no mistake, when this phase of my work is done it will only be a mere OUTLINE.  Despite being way more than 1,000 pages in length, assembled over more than 20 years of time, it will only be a basic foundation upon which future studies and works will add, update, and modify as needed over time as new information and knowledge becomes available.

My hope in this process is only to make a POSITIVE contribution to the world around me, amid this precious, flicker of time which I am blessed to have in this life.

A positive contribution in this matter is bringing understanding to what the High Knob Landform is, what it contains, and what it truly represents from the foundation of the natural sciences ( generating a BIG picture ).

Not from speculation, or guessing, or fiction, but from reality of what is, documented over time for anyone to prove.

Any new terminology or concept may sound strange at first, but over time when proven to be fact it becomes commonly used and natural.  It is in this manner that I work to encourage usage and recognition of the terms "High Knob Massif" and "High Knob Landform," as they apply in scientific works, common writings, or in any usage in which they are valid.

This work is not biased toward 
anyone or group. 

Period! 

It is for the United States Forest Service, the National Park Service, the City of Norton, Towns of Appalachia, Big Stone Gap, Coeburn, Dungannon, Duffield, Pennington Gap, Jonesville, and many others, The Clinch Coalition, The Nature Conservancy, ALL private citizens, students, and teachers that live on or adjacent to the HKL, and for all counties and states into which it extends.

This work is simply for EVERYONE in order that all may learn about this great landform for a better, more postive future for it and everything impacted by it.

This work is NOT associated with any environmental group, and has not been funded by any groups.

It is also done to stimulate and encourage future scientific studies, which up until the past decade or two have been blatantly lacking across this great landscape ( ** ). 

**That is, outside of the endless search for hydrocarbon resources and extractive entities.

How could a great landform like the HKL
go unrecognized for so long?

The answer to that question rest's largely upon the former, since no one expected to find, or went looking for, a great natural landform amid the Appalachian Coalfields.

My father was a coal miner for 40 long years, and this is no rebuke of that profession, but merely a part of the reality.

How could the deepest cave system east of the Rockies, and north of Mexico, on the entire North American continent go unrecognized for so long? 

It's been here all along ( i.e., for a very long time )!

The answer is again part of the reality, that the focus of attention had previously been placed upon other better known karst regions across Virginia and the United States prior to the 1990's.

Such has been the case with EVERY major branch of the natural sciences except for geology, since detailed geological studies were necessary from a hydrocarbon perspective.

And just what was discovered when
the geology was studied in detail?

Only a little thing named the Cumberland Mountain Overthrust Block ( called Pine Mountain Thrust Sheet by some ), a recognized world-class example of "thin-skinned" tectonics, which has been cited in more scientific works, books, and papers than anyone has time to list.

It only revolutionized world-wide thinking about how thrust belts form and function in the creation of mountains!

With such a unique and fascinating structural framework, should it really be so shocking that such a great natural landform has developed upon it, down within it, and across a large portion of it's 3125 square mile expanse? 

No, it really should not.

But there is so much more!

Like the human body has a soul which can not be seen with the naked eye, or explained by the natural sciences, the High Knob Landform ( HKL ) possesses an ability to alter and change invisible properties.

As I have written many times in the past, occasionally some of these "invisible" forces become visible to our eyes as the HKL, and it's remnant massif, alters the fluid atmosphere such that gravity waves appear ( given sufficient moisture for condensation processes ).

This has been important in my research, and I want to highlight this bit below from a former writing:

"The greatness of the HKL reaches far beyond what can be seen with the naked eye. From a climate perspective, this mountain landform is a force to be reckoned with, and is like a massive boulder in a river, that deforms the water and forces it to change course.

In this case, the High Knob Massif deforms the very air. If it were removed from the landscape, the regional climate would change, natural entities of untold significance would be lost, and lives near and far would forever be different, regardless of whether or not they ever laid eyes upon this massif.

Like many of the taller mountains of the Appalachians, the High Knob Massif excites gravity waves in the atmosphere.

However, unlike typically narrow crested Appalachian ridges, the unusually wide base to base width of the High Knob Massif, coupled with its good airflow exposure, forces much greater orographic impacts than would otherwise be expected from a mountain whose summit stands 1500 vertical feet lower than the highest in Virginia.

[ Analogy:  A tall, narrow rock sticking up out of a river will alter the flow, but a wide rock; although lower in height, will deform the flow of the river in a much greater manner ].

The High Knob Massif generates, dissipates, and transfers enormous amounts of energy to places far removed from where it stands, with traces of this energy transfer being followed by the trails of gravity waves that ripple outward away from the massif through the fluid atmosphere in all directions."

That bit of writing hints at some of the great forces at work which we occasionally see revealed, like this incredible NASA visible image above illustrates.  A great flowing river of deformed air, orginating amid the High Knob Massif, which transfers energy outward through the fluid atmosphere to places as far away as western North Carolina or beyond.

Remember, a WIDE rock in a river!

There are other things emitted by the High Knob Landform which may not be readily seen or realized, until something "tragic" happens like the burning of the grand old Lookout Tower. 

A rash of emotions were then revealed, even though what was really causing them was MUCH MORE than a mere pile of wood.  Yes, it was indeed a grand ole tower, but it was the HKL that made it so beloved.

And, of course, there is the great cultural apsect of the HKL which has not even been mentioned.  The famous Wilderness Road, grand Cumberland Gap, are only the most famous parts of a long legacy of national history made within this great landform.

One would think that Tourism Authorities would be JUMPing
at the chance to tie all this together into one grand package. 

Are you listening out there? 

It's called the High Knob Landform ( HKL ), or Powell Valley Anticline ( if you are strictly pushing geology ).

And now, as I also often like to say,
here is the BOTTOM LINE:

I did not wake up one glorious morning with the great realization of the High Knob Landform.  I did not go in search of defining the HKL.  I stumbled across it more than 20 years ago on the road to discovering some incredible climatic features unique to Virginia.

That is where this scientific study all began for me ( it really started when I was just a kid, the first time I looked upward in amazement at the 2000+ feet of vertical drop off Grindstone Ridge Dome in the Head of Powell Valley )!

But, as I was well taught at the University of Virginia's College in Wise, one can not truly define something without first stepping back to see the BIG PICTURE.

Like a large puzzle that begins as an unsorted pile, pieces were scattered from here to there, and only slowly, over time did they begin to emerge into this GREAT, GRAND picture that is the HKL.

Many greater ones than I have added pieces to this puzzle in years and decades past, and many greater than I will do so in the years and decades to come ( MY HOPE ). 

It really does not bother me if my contribution passes away with time, IF the HKL becomes recognized by scientific studies, local, state, and national agencies responsible for it's care, and generally loved and appreciated for what it contains and represents.

A BIG dream? 

Not really.

I think the majority who see High Knob sprawled across the great horizon with its lofty basins, gorges, lakes, wetlands, and plunging whitewater creeks, the awesome view of Powell Valley nestled deeply amid its towering mountain walls, tumbling Roaring Branch Gorge, Keokee Lake, the beautifully rolling Clinch & Powell River valleys which finally unite like passionate lovers at its southwestern end, the great Cumberland Gap National Historical Park with its looming "White Rocks," can sense in their hearts that this is no ordinary landscape! 

When they learn of all the incredible things not so readily visible and talked about, which have been discovered far above, upon, and far beneath its surface, and that ALL of these are connected to ALL of those above which are so readily visible, amid a SINGLE great landform, there will be no possible way to deny what it is. 

They will simply KNOW!
