This is a variant of the myth that a cave runs under the river from the bluffs on the south side of the river to Chilhowee Park. There are caves under all of Knoxville, since the city is built on karst, but there is no known cave that runs from UT to Chilhowee Park or from UT to anywhere else, for that matter. There are caves on the river side of the university—some are covered with underbrush along the railroad tracks to the west of the main campus, and some are relatively visible.
