Linear terrain in the Appalachians.jpg

Long low ridge-lines in the middle Appalachians, likely somewhere near the long line of Interstate 81, which follows these parallel folds of land all the way from Knoxville, on the eastern edge of Tennessee, up the western border of Virginia and through the narrow neck of West Virginia into Harrisburg, Pennsylvania.  We drove this line once a few years ago, and the countryside is beautiful from the ground as well.
