Dismals Canyon is a sandstone gorge near Phil Campbell in Franklin County, Alabama. It was declared a National Natural Landmark in May 1974. Dismals Canyon is one of only a few places where insects called dismalites can be found. The larval forms of these flies emit a bright blue-green light to attract food and mates.
