Temporal and Spatial Distribution of Concave Base Projectile Points from the North Coast Ranges, California


Our study found that the Small point type has a distribution to the north and west of the Clear Lake basin; however, there is conflicting and limited evidence on the temporal position of this type. In the Northwest Coast Region, specimens similar to this type have been associated with the late prehistoric period (Milburn 1977), while in the North Coast Ranges Region, there are preliminary indications that the type was in use during an earlier period. If the Small type was contemporaneous with the Shallow Base and Shallow Base Shouldered types, then this assemblage appears to be restricted to the western portion of the North Coast Ranges. On the other hand, while numerous Small type specimens were found north of Clear Lake, only a few of the Shallow Base or Shallow Base Shouldered point specimens were found in this area.
