Ranges

* Wisconsin Range (), is a major mountain range of the Horlick Mountains, comprising the Wisconsin Plateau and numerous glaciers, ridges and peaks bounded by the Reedy Glacier, Shimizu Ice Stream, Horlick Ice Stream and the interior ice plateau. * Long Hills (), a group of hills and rock outcroppings about in extent, located midway between the Wisconsin Range and the Ohio Range. * Ohio Range (), a range about long and wide, extending west-southwest – east-northeast from Eldridge Peak to Mirsky Ledge. The range forms the northeast end of the Horlick Mountains and consists primarily of a large snow-topped plateau with steep northern cliffs and several flat-topped ridges and mountains. The highest point, , is the summit of Mount Schopf.
