Sequoyah Caverns is a large cave system in northeastern Alabama. The main cave, open for commercial tours, is the object of this study. Its features, including speleothem formations, erosional wall patterning, fossilized marine creatures, and an unusual sedimentary deposit containing allogenic pebbles and disarticulated fossil mammals, all indicate the rapid and energetic development of this cave within the recent past. The cave system and its surrounding strata are easily explained by the processes of the Genesis Flood and its aftermath.
