Encino Point

This projectile point exhibits a triangular morphology with a stemmed to expanding stem configuration, characterized by an elliptical cross-sectional profile. The blade displays an excurvate shape, where the edges curve inward toward the apex, occasionally approaching a parallel alignment at the blade's widest point, distinguishing it as a Type I variant. In contrast, Type II points typically do not exhibit this parallelism. The shoulders are notable for their barbed morphology, often oriented downward or inward. The stem's shape varies from nearly parallel to slightly expanding, while the base ranges from straight to subtly concave, with basal corners that are consistently rounded. The flaking pattern observed on this point is random, lacking a discernible order or orientation.

The arrowhead's dimensions are as follows: it measures between 27 and 48 mm in length, with a stem that ranges from 12 to 17 mm in length. The blade's width spans 18 to 28 mm, while the stem's narrowest point is between 12 and 15 mm wide. At its widest, the stem measures 12 to 16 mm, and the overall thickness of the arrowhead varies from 5 to 9 mm.

This variant is documented in Cueva de la Nopalera, Hidalgo, Mexico. Such artifacts are believed to occur extensively across the Valley of Mexico.
