In a layer above that containing Folsom points at Blackwater Draw, several varieties of unfluted lanceolate points were found to be associated with the bones of fossil bison. These points have been identified by various specific names such as Plainview, Milnesand, Eden, and Scottsbluff from excavated sites elsewhere in the High Plains region, and probably range in age from 8000 to 10,000 years. Although the giant bison still survived into this level of stratigraphy and time, the elephant, camel, and horse of the Clovis level had disappeared from the area. [Illustration: Figure 1.

Below cave deposits containing Folsom points was an earlier type of point among the bones of mammoth, horse, camel, and other large Pleistocene mammals. Now identified as Sandia points, these projectile tips are distinguished by an asymmetric stemmed form with a shoulder on one side. The age of the Sandia points has been a subject of some controversy, but the latest available data from charcoal in Sandia Cave indicates an age of nearly 12,000 years, which is within the accepted range of the Clovis points.
