High Knob Massif
Looking at High Knob Lookout
A beautiful array of rime and snow blanketed the high country as the first widespread snowfall of 2023 finally arrived.
A general 3" to 8" of snow fell across the mountain area, with heaviest amounts at upper elevations across the High Knob Massif.
This occurred despite the best moisture plume from the Great Lakes passing to the southwest of the Cumberland Mountains into the Great Smokies.

(M): Some missing moisture in undercatch and frozen precipitation, with corrections applied for the 24.4 meter (80 feet) tall dam structure where rain gauges are located. Corrections are based upon 86-months of direct comparisons between NWS and IFLOWS at Big Cherry Dam (including occasional snow core-water content data).

Local snow drifts were much deeper as suggested above by areas of wind blown snow along the road up to the
High Knob Lookout.
A distinct temperature inversion was once again visible following clearing into 24 January above river valleys (Clinch, Holston) downstream of the High Knob Massif and Cumberland Front.

Highlights of January 2023
Calcareous Heart of High Knob Massif
An idea for the great beauty and diverse climate of this area can be obtained by viewing highlights of conditions captured from a camera at Mountain Empire Community College in Big Stone Gap.
*Scroll through the picture viewer with keyboard arrows or other means to put these scenes into a time-lapse type of motion for interesting viewing.
This is looking northeast along Powell Valley in Wise County, Virginia nestled within the breached, calcareous heart of the great High Knob Massif.
This Appalachian karst valley has been opened up (eroded or breached) along the axis of the geologic Powell Valley Anticline, what I have also defined as the High Knob Landform.
My research views the High Knob Landform as being analogous to the human body, while the Powell Valley Anticline is analogous to the structural support or skeleton for that body.
Neither the Powell Valley Anticline nor the
High Knob Landform exist alone, they are
complementary and part of an incredibly
complex system.
A system whose beauty is
rivaled only by its diversity.
