Mummy Cave

6300–4300 BCE, Plains Archaic

Mummy Cave is named for the deeply stratified Mummy Cave on the North Fork of the Shoshone River in Park County, Wyoming, excavated by Wedel, Husted and Moss, whose Early Archaic levels produced this form. It defines the Early Plains Archaic side-notched horizon across Wyoming, Montana and the Rocky Mountain front. Local cherts, quartzite and obsidian are used.

Diagnostic traits

Side-notched dart point with notches set low on the blade, a straight or slightly concave base that may be ground, and a triangular blade with a lenticular section.

Identification

Mummy Cave is separated from Bitterroot and Northern Side-notched, its Plateau and Great Basin contemporaries, largely by region; Hawken is slightly later with wider, shallower notches. Oxbow has a deeply concave eared base.
