Jay Point

This stemmed point exhibits a distinctive morphology, characterized by an elliptical cross-sectional profile and a medium to large size. The blade's curvature is predominantly excurvate, although some specimens may display a straight configuration. The shoulders are subdued or, in some cases, virtually nonexistent, and are marked by an upward inclination. The stem's orientation can vary from straight to slightly flared, and its length is notably longer than that of most comparable points, often rivaling the blade's length. The base of the point presents a range of forms, from straight to convex, and features evidence of grinding in the basal and hafting regions. The flaking pattern observed on this point is random, lacking a discernible order or organization.

The dimensions of the arrowheads are as follows: they range in overall length from 31 to 65 mm, with a mean length of 47 mm. The stem length varies between 14 and 35 mm, averaging 25 mm. The width of the blade spans 15 to 42 mm, with an average of 23 mm. At the shoulders, the stem width measures between 13 and 38 mm, averaging 22 mm. The basal width ranges from 9 to 17 mm, with a mean of 13 mm. In terms of thickness, the arrowheads measure between 5 and 14 mm.

Specimen occurs from Mexico to southern Arizona and into the central Rio Grande Valley in New Mexico and into Texas. This variety was discovered at the la Paya site in northern Sonora, Mexico
