霍利克山脉俄亥俄州范围内七叶树冰碛岩之下和之内的条纹和相关构造表明二叠纪（？）冰川向西南偏西移动。霍力克山脉威斯康星州的条纹显示出类似的方向，但运动的感觉无法确定。海王星山脉和彭萨科拉山脉的科迪纳峰的古冰川向西南偏南方向移动，但有些分散。在俄亥俄州山脉和彭萨科拉山脉，古水流与冰的运动平行，但在彭萨科拉山脉，古水流也向东北偏北方向流动。
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.
