Phil Shelton ( professor emeritus of UVA-Wise ), Jerry Rose ( Virginia Master Naturalist ) and I hiked part of the main wetland valley on this gorgeous day in early May.


Although more freezing nights are upcoming in the high country, the second half of April found spring emergence accelerate within the upper elevations.

Big Cherry Wetland Valley 4
April 2017 Temperatures
Elevation 3187 Feet Above Sea Level

Average Daily MAX: 64.5 degrees
Average Daily MIN: 39.9 degrees
MEAN: 52.2 degrees
Highest Temperature: 84 degrees
Lowest Temperature: 25 degrees

Mean low temperatures for the month of April came in just under 40 degrees within colder portions of the wetland valleys.

These high valleys continue to generate the coldest nocturnal temperatures in western Virginia, with consistent decoupling and inversion formation supporting cold air drainage-pooling.

The April 1 to May 1 period produced around 11.00" of total precipitation within upper elevations of the High Knob Massif, including accumulating snow.

Northern Hardwoods Ecosystem

( Trillium undulatum ) and very small Anemones 
( Anemone quinquefolia ).

A few other species include:

Long-spurred Violet
( Viola rostrata )

Wild Geranium
( Geranium spp. )

Foamflower
( Tiarella cordifolia )

Mayapple

The forest understory along the valley is full of 
Vaccinium species along with American Beech 
( Fagus grandifolia ) and Striped Maple 
( Acer pensylvanicum ).

Fern Species

Large clumps of Cinnamon Fern fiddleheads are 
emerging along with many other species such as:

Bird Species

Even if it were not visible that we were within a Northern Hardwoods ecosystem, the sound of singing Magnolia Warblers ( Setophaga magnolia ) heard all along the valley would indicate a northern setting.  Dr. Phil Shelton positively identified the birds with his binocular.

Magnolia Warblers have just recently returned to the high country, as during my April 15 hike down the wetland valley I did not hear any singing.

Whitewater was gushing out of Big Cherry Lake basin following the latest significant fall of rain.

With a general 12.00" to 14.00" of rain since April 1 it is not hard to get the whitewater churning.

Drying air and bright skies during the afternoon 
set the stage for a chilly night, with temperatures dropping into the 30s up in the high country 
within Big Cherry Lake basin ( * ).

A wet spring season during 2017 has made it difficult to cut hay grass and to even keep up 
with regular mowing.

Antecedent wetness set the stage for flooding rains during May, with flash flooding recently occurring in the Town of Clintwood and within East Stone Gap & Cracker Neck of Powell Valley.

More than 3.00" of rain fell at Big Cherry Dam during May 27 to push the monthly rainfall total up to 10.00" and the April-May tally to around 16.00" ( 26.00" in Spring 2017 ).

I measured 8.15" of rain at Big Cherry Dam for the May 9-27 period ( nearly 2.00" fell prior to May 9 ).  The month of April generated around 9.00" at Big Cherry Dam, with a general 8.00" to 10.00" in the City of Norton to Big Cherry Dam corridor of the massif during April.

A general 35.00" to 40.00" of total precipitation has fallen in upper elevations of the High Knob Massif so far during 2017.  That comes on the heels of 12.00" to 16.00" which fell during the November 28-December 31 period, to make a general 47.00" to 56.00" during the past 6 months. 

( Around 51.00" to 52.00" in the past 6 months on average ).

An interesting mixture of species is typical in 
this wettest area of Virginia, with a vast carpet 
of mosses and lichens growing beneath both Mountain Laurel ( Kalmia latifolia ) & Rosebay Rhodendendron ( Rhododendron maximum ).  Ferns are prolific and widespread in this area. 

Yellow Buckeye
Aesculus flava )

Yellow Birch
Betula alleghaniensis )

Tulip-poplar
Liriodendron tulipifera )

American Beech
( Fagus grandifolia )

are common, along with many other species, near
 the Big Stone Gap Water Plant in South Fork Gorge.
