Striae and associated structures beneath and within the Buckeye Tillite in the Ohio Range of the Horlick Mountains show that Permian(?) glaciers moved toward the west-southwest. Striae in the Wisconsin Range of the Horlicks display similar orientation, but the sense of movement could not be determined. Paleoglaciers in the Neptune Range and the Cordiner Peaks of the Pensacola Mountains moved toward the south-southwest with some dispersion. Paleocurrents flowed parallel to ice motion in the Ohio Range and in the Pensacolas, but they also flowed toward the north-northeast in the Pensacolas.
