It takes awhile for the morning haze to burn off on top of the Smokies as is evident from this photo of Derek's Knob Shelter.
Chainsaws are not allowed on the trail due to noise and air pollution. All the trees are felled with crosscut saws.
A good book, a fire in the fireplace makes for a semi-comfortable day in the shelter. The Smokies receive an average annual rainfall of 82".
"Pulaski's" are the workhorse of the tools used. Every member of the S.W.E.A.T. Crew carries in one or two tools in addition to what's in their backpacks bringing the total weight carried by each crew member into the 60- to 80-pound range.

S.W.E.A.T. stands for "Smokies Wildnerness Elite Appalachian Trail" Crew. The "Delta Force" of trail maintenance.
The tools are hung and stored each evening before everyone relaxes over dinner.
In many places the AT is 12 - 18 inches wide and follows along a "knife edge ridge". Fall to one side and you're in Tennessee. Fall to the other and you're in Virginia.
