The aphid was accidentally introduced to this area in the 1950s and has wreaked havoc on fir trees ever since. Once infested, most firs die, leaving behind only bare, gray snags as a grim reminder of the aphid's presence. Some scientists are encouraged, however, that the firs will be able to stage a comeback, as each new generation grows increasingly resistant to the menace. The 360-degree view from the top presents very little sign of civilization, and the scene is majestic. Hawks, ravens, vultures, and occasionally eagles and peregrine falcons ride the hot air currents that rise from the valley.
Rock climbing is also popular here.
Research into the size, weight, and numbers of the northern flying squirrel is regularly conducted in the higher elevations surrounding Devil's Courthouse. The endangered species, which averages 10 inches in length and 5 ounces in weight, lives on seeds, lichens, and mushrooms. Active mostly at night, the northern flying squirrel is rarely seen gliding through the air, using folds of skin running from its front to back legs much like a parachute with its tail as rudder. The trail begins by running north along the Blue Ridge Parkway and then ascends into the woods. They plan to open a larger retail store near the Asheville area, but for now, they have dived into the world of the 'net.
