This past weekend Dudeboy and I joined Vic, Keith and a few other friends for a couple of hikes in the Big South Fork region of Kentucky/Tennessee. We saw several significant arches and many windows (several of which are undocumented).
The opening of this arch made a perfect outline of a bird . . . a crow maybe?
McCreary County, Ky. Look for the natural bridge about a third of the way down and on the left hand side.
