The High Knob Landform

Wayne Riner Photograph Thoughts...
"It was the first spring morning, and it came with a welcomed blast of color.  As I studied the colors with my eyes, my ears listened to the long and beautiful mating call of the Robin from the orchard below."

March 21 marked the first full day of Astronomical Spring in the Northern Hemisphere, known as the Vernal Equinox, when the sun on its northward "march" ( no pun intended ) crosses above the Equator to generate nearly equal lengths of day & night
in both hemispheres.

For climatological record keeping, however, the three month period of March through May is considered to be the season of spring.


 A Glorious Early Spring Renewal
           
Following in the wake of a long winter slumber, spring is a time of rebirth and renewal.  A time of glorious awakening!

Perhaps no where on earth is the majesty of this special season as evident as in the Appalachians, where the richly varied landscapes of these ancient mountains are renewed by the interconnected rhythms of life ( astronomical, terrestrial & subterranean ).

For many humans the process of spring renewal is exemplified by the appearance of wildflowers and the melodious singing of song birds.  In such a manner the interconnected rhythms of the natural world merge, and reach forth to touch the invisible realm of the human spirit itself ( soul within )!

It has been said, and much scientific evidence supports, that "modern age" humans become increasingly troubled when they lose contact with the natural world around them, disrupting the interconnected rhythms which make us all part of this wondrous and complex array of Life on Earth.

A natural world of life which, as this website strives to illustrate, includes SO VERY, VERY MUCH MORE than merely wildflowers and birds ( as grand as they truly are )!

Wayne Riner Photograph Thoughts...
"The warmer days have brought sure signs of spring.  Along with hearing the Robin’s song in early morning and late evening, Coltsfoot can be seen growing in dry, sunny spots along roadways on Long Ridge.

Eastern Bluebirds are looking for nest boxes, but most notable is the return of Tree Swallows from Central America. Their return being about two weeks later this year because of colder weather."

My nature journal records that the first Coltsfoot bloomed last year during early March, within the Clintwood to Long Ridge corridor of the Russell Fork Basin, with March 21 being the date observed along the High Knob Mountain Road ( Rt. 619 ).

Tree Swallows were observed flying above Long Ridge by March 10th in 2009.  All dates being around 2 weeks earlier than this year as my friend Wayne Riner noted.  

Spring in the southern Appalachians is like few places on planet Earth, as a truly vast and magnificent diversity of life forms emerge from winter slumber to join migrating multitudes amid this most wondrous season of change!

Scarlet Cup Fungi ( Sarcoscypha austriaca )

The beautiful Scarlet Cup mushroom is one of the first to appear in spring. It is of the Ascomycota phylum, and is a saprobic fungi which does a great service by helping to decompose already dead wood ( i.e., it does not attack living wood and is therefore not parasitic like MANY fungi ).

Life on Earth would simply NOT be 
possible without decomposing organisms!

A great summary of this is presented by my friend
Dr. Paul Marek, within the blog section of his website:

Millipedia Blog - January 24, 2010 - All Life Decomposes

Trout Lily ( Erythronium americanum ssp. americanum
Photograph by Richard Kretz - © All Rights Reserved.

Yellow Trout Lilies are among the very first woodland wildflowers to bloom in spring.  My nature journal records that lower elevations can expect blooming to begin during mid March to 
early April on average ( during the past decade ).

I have always found it difficult to take a good photograph of these early bloomers, unlike my talented friend Richard Kretz!

Sharp-lobed Hepatica ( Hepatica acutiloba )
Photograph by Richard Kretz - © All Rights Reserved.

Hepaticas begin blooming during March within lower elevations, and late March or April across middle to upper elevations.  My friend & naturalist Richard Kretz captured the above beauty blooming on March 18, within calcareous soils of majestic Pinnacle Natural Area Preserve ( NAP
of the Clinch River Valley.

Sharp-lobed Hepaticas are most common in soils weathered from calcareous rock stratas, while the Round-lobed Hepatica
( Hepatica americana ) tends to be more typical of soils derived from acid based stratigraphy ( the most widespread species in Virginia since acid based rocks are most common ).

They are also called Liverworts, and may not bloom until late April or early May amid higher, colder sections of the High Knob Massif ( especially during cooler springs ).

In the High Knob Landform where calcareous and acid-based stratigraphy are well mixed, these preferences will often dictate which species of hepatica grows where.

In the High Knob Massif, in particular, where many slopes contain both rock types, it is not uncommon to find both species of hepatica growing at different elevations.

A rather ironic twist, since in this case the variation in species type is being controlled more by stratigraphy than by influences of sheer elevation itself.  

The ability of light to pass unfiltered through the forest canopy is simply vital to the emergence of the kind of magnificent, woodland wildflowers for which the Appalachians are most famous.

These wildflowers are often referred 
to as spring ephemerals.

Ephemeral meaning short-lived, or transitory.

Bloodroot ( Sanguinaria canadensis )

Bloodroot is a nice example of a spring ephemeral that possesses a relatively short blooming time for individual plants.

They typically bloom during late March and especially April within the High Knob Landform, while cold weather and snow is still observed.  The distinctive leaf above often wrapping around young plants like a little blanket.

In a sense the term ephemeral is correct in that the flowers or blooms of each plant do last for only a short time.  However, most of the herbaceous wildflowers of spring are actually perennials.

A perennial plant being one that persists from year to year.  Most of these hardy beauties ride out the cold season underground, invisible to the above ground observer as bulbs, corms, and rhizomes.

These are all just storage organs where complex carbohydrates, like starch, wait anxiously for the right astronomical & atmospheric signals that flowering time is at hand.

It is really quite ingenious!

Bird's-eye Speedwell ( Veronica persica )

Bird's-eye Speedwell is not a native wildflower.  It is one of many introduced species of Veronica which have spread across the landscape.

The American Speedwell ( Veronica americana ) is one of only a few which are native in this genus.  However as busy ants above illustrate, whether for good or bad, it fills ecological niches that are exploited by many species.

The longer days and warmer temperatures of spring are the signals desired.  As they light and warm the forest floor chemical messages are transferred underground to storage organs 
of the slumbering beauties to be!

Storage organs rich with hidden energy that is locked away in the chemical chains of multitudes of complex carbohydrate molecules.

With one final added ingredient, water, the assault begins and complex carbohydrates in storage are broken down into usable forms of energy.

Growth begins and a precession of spring ephemerals magically break through the leaf litter across a light filled forest floor to transform the landscape from muted to magnificent!

A really big WOW!

However, it actually is even more wondrous!

Spring Beauty ( Claytonia caroliniana )

Spring Beauty is a true harbinger of the new season and ideal example of a native ephemeral with rich, tuber-like storage organs from which they renew themselves.

Each comes in its own time, according to its own unique genetic programming!

Like the combination of a safe, a precise mixture of light, temperature, and moisture is required by each species before the genetic program embedded within will recognize that its time to open the doorway to growth & flowering.

Trailing Arbutus ( Epigaea repens )

Trailing Arbutus actually falls into the classification of a low growing evergreen sub-shrub, but it is also one of the first lovely wildflowers to bloom in spring.  Blooming times varying with elevation and exposure ( of course ).

In this way, flowering times for individuals of the same species vary across the mountains as light, temperature, and moisture varies across the complex terrain itself.

It is also in this way that species favoring less light, more light, lower temperatures, higher temps, less moisture, more moisture, and specific chemicals weathered from specific soil types are ultimately constrained by an intimate mix of environmental parameters and genetics to favored sites across the landscape.

From this BIG picture perspective,
is it not truly just wondrous!

Blue Violet ( Viola spp. )

More than two dozen species of violets grow within the area, with identification of specific species often made more difficult by their tendency to hybridize. 

The ultimate source for rebirth of glorious spring ephemerals, of course, being photosynthesis 
( essentially the only mechanism of energy input into the living world ).

While this is no classroom, it is important to summarize as follows:

Photosynthesis is simply an oxidation-reduction reaction with the big picture of the process featuring an oxidation of water 
( with removal of electrons & release of oxygen as a by-product ) and a reduction of carbon dioxide ( yielding formation of organic compounds such as carbohydrates ).

Photosynthesis produces the carbohydrates that make up the storage organs which are then used later to renew the process all over again!

By this process, in the BIG picture, planet Earth literally breathes IN and OUT with incredible synchrony!


Upward spikes in this chart being due to winter respiration of the Northern Hemisphere, with it literally letting out an enormous breath enriched with carbon dioxide as its ecosystems go dormant and photosynthesis diminishes.

The downward spikes in the chart above, by contrast, being caused by summer photosynthesis of the Northern Hemisphere as its ecosystems come alive and breathe in more carbon dioxide than they respire ( breathe out ).

The problem, of course, with the above charts being the steady, well documented rise of mean CO2 concentration over time since recording first began during the 1950s ( a subject for another day ).

Is this steady CO2 rise truly a problem given its small mass per unit volume in the total atmospheric mixture of gases?  In reality, it is only a trace gas amid any given volumne.  You are free to make up your own mind!

Black-and-White Warbler ( Mniotilta varia )

Black-and-White Warblers will be among the first of our beloved warbler troop to return, and should be listened and watched for into early April.

UPDATE: I heard the first Black-and-White Warbler on March 29 ( of 2010 ) in the Clintwood area of the Russell Fork Basin.  Expect an increase in neotropical migration as winds turn S to SSW from the Gulf of Mexico & Caribbean during early April.

The main purpose for showing the above charts now being to illustrate that the Rhythms of Life associated with our simply wondrous Appalachian rebirth can literally be seen by the breathing of planet Earth herself!

What may seem as only happening in your backyard, across the High Knob Landform, the Upper Tennessee River Basin, or the Appalachians is ALL connected in ways which are only beginning to be understood.

But make no mistake, everything in the natural world is intimately connected and interconnected, from above, on, and below the surfaces of planet Earth outward into the cosmos itself ( even though we still do not yet fully understand how its all linked, to be absolutely honest and sincere from a scientific perspective ).   


More Diverse Species Of Current Interest

Mallard Duck ( Anas platyrhynchos )

Mallards are spring and fall migrants into the area, and according to Dr. Richard Peake can be both summer and winter visitors that occasionally breed ( the status of this species in the wild, being complicated by feral local ducks ).

Eastern Screech Owl ( Otus asio )

This sleepy little Screech Owl is a fairly common resident of the mountain area, with its eerie calls being a treat to hear on dark and gloomy nights ( as well as starry ones too )!!

I just love these little fellows!

The Screech Owl is the only small owl
in the eastern United States with ear tufts.

Striped Skunk Tracks ( Mephitis mephitis )

Some nights this little owl may be looking down at one of the two common skunk species in the area, whose tracks Richard captured above.

The other species being the Eastern Spotted Skunk ( Spilogale putorius ). 

Spring Stonefly ( Prostoia completa )

Spring Stonefly is of the order of insects named Plecoptera and, like Mayflies, its presence in a stream, pond, or lake is typically an indicator of good water quality.

Stream monitoring is very important.  To find out more, and how you can help, please reference The Stream Monitoring Program for the High Knob Massif area:


Endemic Millipede ( Brachoria cedra )

The Cedars Millipede ( Brachoria cedra ) is endemic to the High Knob Landform and known only from Lee County and the High Knob Massif area of Wise County.

Field research by Dr. Paul Marek has been so significant that a revision of the genus Brachoria has now been made, with much of the research centered within the High Knob Landform.

Much more will be presented about these amazing creatures and Dr. Marek's research in future editions of this website.
Stay tuned!

Earthstar Mushroom ( Geastrum sp. )

It is about time for Earthstar Fungi to begin appearing within mountain forests of the great High Knob Landform.  These mushrooms are named for the unique way in which their outer spore body wall splits into an amazing star shape.

Fancy Fern is also called Intermediate Wood Fern but in both cases retains, as do all species, its universally given scientific name of 
Dryopteris intermedia ( * ).

*This is why its so important to always list the scientific name when introducing a species of flora or fauna, since common names often vary greatly between regions!

Spring Snow - High Knob Massif

Snow depths in the view above vary from more than 4" on the left side of the steps to less than 1" within wind exposed sections via air blowing from right to left across this scene.

Snow accumulations across the High Knob Massif were most significant, with ground depths varying from less than 1" over some graveled and wind swept surfaces to more than 6" in drifts.

Melted water contents suggesting between
3" and 4" of total snowfall at higher elevations.

Darlene & Joe Fields measured 2" of ground depth in High Chaparral, at 3300 feet elevation, to make 10.0" of snowfall during March and 124.0" during the 2009-10 season.

March snowfall totals reached approximately 15" 
in snowier sections of the High Knob Massif where 
winter tallies reached the 150-200" range.

Low clouds held tough through much of March 23 which featured unseasonably cold conditions.  Solid snow continued to blanket highest elevations into March 24.

As clouds finally began to give way to clearing
an array of orographic gravity wave clouds were
seen on NASA Imagery during March 23.

Frosty cold beauty greeted a magnificent dawn 
on March 24 as blue mountain walls of the high country surrounding High Knob towered above Powell Valley in Wise County.

The above foreshadowing the next weather system which spread rain and wind across the mountains by late on March 25.

Another blast of unseasonable, winter cold followed during March 26 when ICY clouds and even more snowflakes engulfed the High Knob Massif. 

In fact, afternoon temperatures plunged into upper 20s all the way downward to elevations of Norton & Wise.

This set the stage for temps to bottom out in the 10s to lower 20s by dawn on March 27 in colder mountain valleys ( above 1500 feet ).

March Madness!


Special Addition - March 27: 
RIME & Hoar Frost

The unseasonable cold of March 26 generated an array of simply gorgeous rime formations across the High Knob Massif with an icy fog and temps in the 20s during the afternoon.  Bitter temperatures into morning hours of March 27, with clearing skies, added hoar frost to the display!

Rime has been covered hard on this website since October 2009 in order to visually illustrate to everyone what a significant aspect of the climate this is to the High Knob highcountry. 

RIME desposition on TREES is a major secondary moisture source for the High Knob Massif, with subsequent rime drop from the trees supplying moisture to snowpacks and bare ground alike.  A key point, being that massive capture of this cloud vapor would not occur without trees!

Before I began writing about RIME and highlighting aspects of my past research in the High Knob Massif on it, and Roddy began to document its nature with stunning photography, most folks in this region were unaware of rime and its significance ( as well as fog drip, hoar frost, and aspects associated with orographic forcing & condensation processes ).

I would like to thank everyone for their interest in this truly amazing climatic aspect of the High Knob Landform!

Past information featuring awesome RIME displays
can be found at the following locations on my website:

( Introduction to RIME )







Remember, rime represents the visual extraction of frozen clouds of water vapor from the air as it is forced to rise across the great High Knob Massif, with deposition upon trees & vegetation.

Its subsequent drop onto snowpacks and soils 
enriches their water contents, further supporting the vast diversity of life forms present in and downstream of this remnant high country of the High Knob Landform and Upper Tennessee River Basin.

Rime is one of the important links supporting the chain of life and its interconnected rhythms, highlighted during this update and throughout this website ( * ).

*Benefits of RIME would be impossible without TREES.
