Commonly Utilized Material:
The most commonly used material is obsidian followed by chalcedony, rhyolite, and ,local and exotic cherts
Additional Comments:

This point shares the same characteristics as the Northern Side Notch and the Bitterroot Side Notch (in the northern Great Basin) with all three having overlapping attributes. Homer (1980), argues that these three types are confusing and have inconstant application. Many differentiate the three types based on region with the Cold Springs found on the Columbia Plateau, the Bitterroot on the Northern Plains and into the Northern Great Basin. Homer did a battery of measurements on the three types and found that there were no significant distinguishing characteristics between the three types.
