Stone Tornadoes in Sipsey Alabama

Stone Tornadoes (lithified vortices) are revealed in this ridge road-cut that skirts a rural highway near Sipsey, Alabama. The ridge rises some 300 feet above the Mulberry Fork of the Black Warrior river to its south, and 45 feet above the highway roadbed. The features were exposed when highway engineers excavated the eastern tip of the ridge during the project to widen Alabama state Hwy 78 to a 4-lane divided highway.
