( Gnomes Too! )


Spring brings the first dazzling color burst as life regenerates for another year with wildly varying shades of wondrous new growth.




Summer produces a continuous display of tones amid many, many life forms as the growing season matures to perpetuate incredible biodiversity!




Autumn, like the final breathe of life itself, generates a sudden explosion of energy that over runs nature's color palette before the onset of winter dormancy.

Autumn 2011 
Color Season History
( High Knob Massif )

During autumn 2011 its a early-mid October peak for the High Knob Massif and upper elevations in Cumberland Gap National Historical Park.

Colorations began developing during mid-late September in upper elevations of the High Knob Massif, above 2700 feet, as they typically do each autumn season ( actual peaking varying with weather ).

Some of these early changing trees amid the cold air drainage of the lake shore lost their leaves by the time Roddy captured the setting on October 12.

If you wish to catch the first vivid colors of the season in the High Knob Massif its important to begin in mid-late September, as this website has now illustrated live for 3 consecutive autumns.

Despite wetness, early colors were advanced by numerous September nights in the 30s & 40s amid upper elevations in the High Knob Massif.

Widespread colorations developed by October 7 to make for many scenic drives along mountain roads in the massif, with just spectacular views reported from overlooks in Flag Rock Recreation Area of the City of Norton.

By the October 15-16 weekend colors were still nice but tending to fade from those brightest hues observed previous days in the High Knob Massif, since mid-late September, with the number of trees mostly bare of leaves at higher elevations about matching those still sporting green upon lower slopes below 2700 feet.

[ Colors viewed from Overlooks in Flag Rock Recreation Area, for example, went from being "spectacular" as described by Michele Knox, City of Norton Parks & Recreation Director, on October 7, to less brilliant but still nice as documented on October 16 by award winning photographer Roddy Addington ].

Comments On General Peak
During Autumn 2011

For the 3rd consecutive autumn season colorations across the area in general have again been sub-par, with more muted tones and less widespread vivid colors than historically observed.

More vivid colors in the High Knob Massif and upper elevations in Cumberland Gap NHP are attributed to a higher concentration of northern species, at least in part, within these mesic, rich forests ruled by abundant moisture ( where color tends to be good to exceptional every autumn as this website documents ).

While pockets of vivid color have been seen across the area, at least for part of the peak, mile after mile of spectacular vistas observed in many past seasons did not develop for many places ( especially those outside the best color locations just noted ).

Yellow Poplar Leaf-mining Weevils ( Odontopus calceatus ) were implicated last autumn as being a factor in that species; however, it now appears that something more significant and widespread may be impacting general forest conditions.

I noted the Shady Dolomite above specifically to ponder if a higher Magnesium component could have supported the Lick Mountain color flare, amid what is a much drier environment, since a lack of Mg and other such nutrients have been implicated in general forest declines by some studies.

[ The above does not explain, however, the lack of color in parts of the Powell & Clinch River basins which have soils weathered from calcareous stratigraphy ( * ) ].

Autumn 2011 color will be recorded as good to locally great in places like the High Knob Massif, and some other higher elevations, but again less spectacular than historically observed for most of the region ( especially lower elevations ).

[ The above being based upon several decades of recorded fall color observations by this researcher ].

With the above noted, its just hard to beat color in the High Knob Landform as both pro and public photographers illustrate very well. Thanks to all!

Major Autumn Storm Brings 
Second High Elevation Snow of Season

October 20, 2011

Snowflakes began swirling during evening hours of October 19 as the second wintry event of this young 2011-12 season coated upper elevations in the High Knob Massif.

[ The first snow began sticking to above ground objects around 2200 hours ( 10 PM ) on October 19 as air temperatures dipped to freezing above 4000 feet ].

NAM Model Initialization At 8:00 PM October 19, 2011

This big storm which dropped 1.50" to 2.00" of total precipitation upon much of the High Knob Landform, was accompanied by strong W-SW winds and a rapid temperature drop. 

NAM Model Initialization At 8:00 AM October 20, 2011

[ Note above that mean 850 mb winds ended up being more W in nature, above a SW low-level flow at the surface ( where 30 to 40+ mph gusts were common ) ].

My friend Denver Garrett measured 1.47" of rain at the northern edge of The Cedars, southwest of Jonesville, where no snowflakes ever fell amid lowlands of the Powell River Valley.

[ While most roofs were blown clean by strong winds, note that the awning seen above the door across this road managed somehow to collect a good bit of snow ].

Snow levels remained higher than I expected given past climatology of cold SW flows into the massif, with sticking mostly amid the main crest zone above 3400 feet in heads of the following:

Benges Basin
Big Cherry Lake Basin
Clear Creek Basin
High Knob Lake Basin
Hoot Owl Hollow Basin

Around 1" of snow was also reported on the ground below the FAA Radar Dome on Black Mountain, some 15 air miles west of the High Knob peak, on the Virginia-Kentucky border.

[ While this event will pale in comparison to most upcoming this season its significance rests in the fact of this being the second one of OCTOBER ( the first snowflakes typically fall amid the High Knob highcountry during October ) with perhaps, DARE I say, one more event before this month ends??? ].

Reference the following link on this website to see how my friend & photographer Roddy Addington captured the first wintry event of October 2011:


NASA Visible At 1831 UTC ( 2:31 PM ) October 20, 2011

It should be noted that the SW flow did its thing during this event across far southwestern Virginia, despite a lack of lower elevation snowflakes, with temperatures that held in the 30s all day in the City of Norton on October 20 ( and around 30 to 32 degrees at the summit level of the High Knob Massif ).

Temperatures in Norton did not rise above the 30s until this gusty SW upslope flow veered W to N into evening hours and diminished in strength, in contrast to places such as Pound, Clintwood, and Haysi where afternoon MAXS reached upper 40s to around 50 degrees on downsloping leeward of the High Knob Landform and Tennessee Valley Divide ( forecasters take note! ).

[ Moderate to strong SW flow events tend to generate cloudier, cooler, and wetter conditions as air is funneled upward through the High Knob Landform of Lee, Wise, Scott counties to the Tennessee Valley Divide VERSES adjacent locations.

Many cases have been documented during the cold season of what some call "freak" snow events within this corridor, that actually are not freaks at all! ].

Mountain valleys experienced their lowest temps of this very young cold season when clouds finally broke, with sub-freezing MINS observed during October 21-23.

Specific Minimums Included ( * ):

October 21
City of Norton: 31 degrees
Jonesville 3.1 WSW: 33 degrees
Clintwood 1 W: 34 degrees

October 22
City of Norton: 27 degrees ( 11 hours sub-freezing )
Jonesville 3.1 WSW: 28 degrees
Clintwood 1 W: 30 degrees

October 23
City of Norton: 27 degrees
Jonesville 3.1 WSW: 29 degrees
Clintwood 1 W: 29 degrees 


( * ) - MINS in mid-upper elevation valleys of the High Knob Massif typically run several degrees lower than those observed within the City of Norton and Clintwood ( the High Knob Massif contains an array of valleys resting between 2400 and 3600 feet above sea level ).

My Mother that just passed believed that the land is what sustains us as a people and nation, with a critical balance being necessary in order to benefit all the people.

Before my High Knob Landform research began in the late 1980s I had not thought much about this balance.  Now I can understand and see it clearly, partly due to the influences of my Mother and my own research, and partly due to responses from many of you ( including, yes, loggers ) that have expessed  your own opinions.

This is the USA and its my hope and prayer that everyone will always be allowed to freely express their own thoughts and opinions on all issues.

With that said, it is critical for everyone to understand that there will always be plenty of opportunities for logging and mining in the counties lying along the Virginia-Kentucky border since the majority of this land is in private and commerical ownership.

Publics lands, YOUR land, in this area offer us all a chance to have at least some degree of critical balance where this smaller proportion of the total landscape can be managed solely for recreation, tourism, and vital water supplies. 

While you are always free on this website to make up your own mind, it should be noted anyone can prove Federal Timber Cuts on Public Lands produce a NET Loss and are an economic drain on both local & regional communities.

While some management of YOUR public lands is good, it should be made crystal clear that the greatest forest on the entire continental expanse of North America ( of which this was at one time ) developed WITHOUT the aid of any MAN!

[ NOTE that the above should read "Forest Ecosystem" since it was complex and interconnected in many ways that we still do not fully understand.  And that truly is KEY.  A forest is more, MUCH more, than just trees! ].

It should also be made crystal clear that local employees for our US Forest Service are some of the finest folks you'll ever meet, and that they are often subjected to orders from "higher up" their chain of command!

Please speak out and express your opinion on this issue to the United States Forest Service and your local & national governments.

On a very personal note, since dealing with the constant sickness and suffering endured by my Mother I now know, no longer just believe, that in order for us to survive as individuals and a society we must have places left free from major impacts of mankind in order to endure what can otherwise be a harsh, cruel world.

The peaceful power of a natural place is vital to the SOUL within us all and contains forces hard to explain which have been inspiration for essentially every religion devised since the initial creation of mankind and development of Life on Earth!

[ The VAST majority of loggers in this area have expressed that they WOULD PREFER that the High Knob Massif area, of which Keokee Lake may be included, not be managed for timber.  They too, believe it or not, are hard working people which like to hunt, fish, and have remote places free from significant impacts of mankind ( * ) ].

*I belong to NO environmental group and this website and research displayed is NOT funded by any groups.  This website is for ALL people and strives to present WHAT IS in a way that anyone can prove and see, the ultimate goal being that a positive difference can be made by showing this landscape ( The High Knob Landform ) in a way never before seen or understood.

[ The first snowflakes of the upcoming 2011-12 cold season began falling at highest elevations in the High Knob Massif as final hours of September waned.

While that is atypically early, such local cold blasts can not be used as a guide to what the upcoming winter will be like here.

High latitude snow cover, especially in the critical Siberian sector, can be used during October as a guide to what the upcoming winter may be like across the eastern USA ].

In the High Knob highcountry September temp means varied from low-mid 60s at highest elevations by day to around 50 degrees in cooler basins by night ( low-mid 50s on exposed ridges ).

September rain amounts were abundant with 7.00" to 9.00"+ totals common from Big Cherry Dam to Bark Camp Lake Basin and the City of Norton.

Thanks to the major early September rain event previously highlighted, local totals for the month approached or exceeded 10.00" in portions of the High Knob Landform.


My friend & photographer Harold Jerrell, for example, measured 9.66" of September rainfall in the Silver Leaf community of Lee County some 14 miles southwest of Jonesville.

Portions of the northern slopes of the High Knob Massif also had totals in the 9.00"-10.00" range, with my friend Andrew Greear reporting 9.21" at the Norton Water Plant.

These rain totals were much greater than amounts measured across adjacent portions of the Great Valley in northeastern Tennessee, with an official September tally of 3.14" in the Tri-Cities.

[ Observe how moisture extraction by windward facing slopes in combination with sinking, or subsidence, of air between wave crests generates sunshine in portions of the Great Valley of Tennessee and leeward of the Appalachians in North Carolina ].

Counterclockwise circulation around a spinning vortex cut-off from main jet stream winds was responsible for the above clouds, which just barely reached the southern Appalachians to limit total precipitation amounts.

[ September 30-October 2 precipitation totals reached 0.26" in the City of Norton, at the northern base of High Knob ( the bulk of what fell on the summit being snow ).  My friends Otis & Nancy Ward measured 0.40" in the Robinson Knob community of High Knob.  A total of 0.27" fell at Nora 4 SSE on Long Ridge of Sandy Ridge ( mostly liquid with some wet snow at 2650 feet ) ].
