A beautiful beginning to the second week of July featured reduced humidity and lower temperatures in the high country, with 40s to lower 50s in mountain valleys.

Elevation 3527 feet
Average Daily MAX: 69.0 degrees
Average Daily MIN: 52.2 degrees
MEAN: 60.6 degrees
Highest Temperature: 75 degrees
Lowest Temperature: 44 degrees
The coldest nights during June occurred in high valleys of the Big Cherry Lake Basin where colder places had average minimums in the upper 40s.

Average Daily MAX: 66.2 degrees

Highest Temperature: 72 degrees
Lowest Temperature: 47 degrees
Rather striking when considering that the typical night
at the Big Cherry Wetland Valley 4 site was nearly the same as the coldest night observed up at the summit level of the massif on Eagle Knob.

*The average nightly low temperature in June observed at Big Cherry Wetland Valley 4 was 11.6 degrees colder than the average nightly low observed in the Tri-Cities, 16.1 degrees colder than in Knoxville, and a amazing 18.8 degrees colder than experienced in Chattanooga ( 66.4 degree average low ).
To no surprise, nights at Big Cherry Wetland 4 were the coldest found along the central-southern Appalachians during June for a valley site ( having a NWS calibrated sensor mounted at 6 feet above ground level inside
of a solar radiation shield ).
Cold air drainage is a dominant feature of complex terrain throughout the year, with summer being no exception, as is being well documented by a University Of Virginia's College At Wise undergraduate field research project
in the High Knob Massif.
Minimum temperature forecasts tend to poorly capture
this microclimatological aspect, that over long-time periods establish conditions which enhance biological diversity.
Coolest mean conditions during June were within the head of the Big Cherry Wetland Valley, where days were cooler and nights somewhat milder inside the woods of the swamp forest ( versus
open portions of the valley floor ).

Although days were warmer in the high valleys than on the crestlines, colder nights allowed mean June temperatures to be around or just under the 61.0 degree average observed on Eagle Knob at nearly 4200 feet above mean sea level.
Rosebay Rhododendron ( Rhododendron maximum )

While Rosebay Rhododendrons are a featured species currently in bloom, many others are blooming or poised to do so within the next few days within the high country. A few notable ones include:
Tall Milkweed
( Asclepias exaltata )
Mountain Black Cohosh
( Actaea podocarpa )

A much cooler feel to the air was experienced during July 29, with lower-middle 60s in upper elevations of the High Knob Massif. This set the stage for temperatures to drop into the chilly 40s within high valleys into morning hours of July 30.

Conditions were unseasonably warm on the hike upward to Cabin Ridge, even amid this highest terrain in Virginia, with the weather station in Grayson Highlands State Park recording a MAX temperature of 79.1 degrees ( 26.2 Celsius )
at 1820 hours on July 19.

The air was unsaturated, such that if the temperature dropped at the standard dry adiabatic lapse rate of 9.8 degrees Celsius per kilometer the maximum at the summit of Mount Rogers would have been 69.8 degrees ( based upon the 79.1 degree Grayson Highlands SP maximum ).

at the 1746 metre ( 5729 feet ) summit
level of Virginia's highest mountain.

Conditions were also unusually dry for the heart
of summer, following a very wet April-May period, with vegetation showing some stress from recent dryness experienced since June 1.

Although he would never state it, or even think
it, Phil is a brilliant ecologist-naturalist and has impacted thousands of students in a very positive manner during his extraordinary teaching career
at UVA-Wise. His many friends know him as a world-class naturalist and human being!
It is always a great privilege to be
out in the natural world with Phil.

While total biodiversity is notably less within the spruce-fir forest at highest elevations on Mount Rogers, this is a unique habitat in Virginia and possesses an assemblage of bird species which might be surprising to many given its latitude.
A few notable species include:
Hermit Thrush
( Catharus guttatus )
Swainson's Thrush
( Catharus ustulatus )
Myrtle Warbler
( Setophaga coronata )
Magnolia Warbler
( Setophaga magnolia )
Dark-eyed Junco
( Junco hyemalis )
Golden-crowned Kinglet
( Regulus satrapa )
Red-breasted Nuthatch
( Sitta canadensis )
Winter Wren
( Troglodytes hiemalis )
American Robin
( Turdus migratorius )
*An American Robin might seem out of place amid all these northern bird species; however, robins breed north to the shores of James Bay and Hudson Bay in Canada and into northern portions of Alaska.

The amount of standing dead spruce-fir is rather striking upon looking upward at the lofty crest line of Mount Rogers. The good news, as observed in previous photographs, being that many young
trees are currently growing well.

A large, sprawling Table-mountain Pine
( Pinus pungens ) might seem out of place in this high country setting dominated by spruce-fir and northern hardwoods. Upon closer inspection; however, a dry, rocky setting that is occasionally burned fits it's habitat description.
