New Mexico, Arizona, southwestern Colorado, and southeastern Utah in the Southwest; morphological and temporal correlates extend up through the Great Basin as far north as Oregon and southern Washington, and throughout Texas to the southeast.
Date Range: 11,000 – 8000 B.P.
Size: Average: 50.2 mm long, 25.3 mm wide, and 8.4 mm thick; stem length: 23.4 mm (Dello-Russo et al. n.d.: Table 1, for Jay points from New Mexico).
Shape: Stemmed-lanceolate, with excurvate to straight sides and weak, sloping shoulders; stem may be as long as the blade.
Cross-section: Lenticular to biconvex.
Base: Convex to nearly straight.
Flaking: Percussion for initial reduction, followed by random and selective pressure flaking.
Grinding: Heavy on lateral and basal stem margins.
Materials: Predominately basalt; less frequently chert, quartzite, obsidian, and other materials.
Other Names: Lake Mojave, Great Basin Stemmed, Western Stemmed, Cougar Mountain, Rio Grande, San Dieguito, Ventana-Amargosa I.
Comparisons: Early Bajada points are similar to Jay points, but have a basal indentation and basal thinning. Large Jay points are similar in size to Agate Basin and Hell Gap points, but generally 1-2 mm thicker.
