Morphology of Projectile Point Types Body Shape (the main outline), Blade Edge Outline, Shoulder Type, and Base Type

Paleoindian Period13,000-11,000 BP

Kitsap County Clovis

Thrusting spears are the primary hunting tool

For a period of about 8,000 years there is little change in the archaeological record of stone tools

There is some regional and possible time variations, but they are still poorly understood

The atlatl is the primary hunting weapon in this period

Hartstene

The Mud Bay Site and some of the projectile points found there.
