This is a picture of the main emergence wave of bats flying up out of Bracken Cave off into the night sky, as the light begins to fade into darkness. This was taken from the lower area down the trail from the cave, near the guano hut. Photo taken with a Canon Elan IIe camera on a Manfrotto Wilderness tripod with a 50mm f/1.8 lens, Kodak Royal Gold 400 film.
