Alternatively, the ridge may be an erosional remnant of an older landform, such as a former glacier bed or kame terrace. The feature studied is located approximately one km west of the Matanuska Glacier terminus, and it trends 340 . Undercutting by a river has created exposures on the southwest side of the ridge, on the opposite side from the modern glacial margin. The ridge is composed dominantly of massive, matrix-supported diamicton, with a greater concentration of clasts towards the top.
Clasts are mainly angular to subangular metasediments, reflecting probable supraglacial transport.
