Golondrina points are of broad lanceolate shape. Upper lateral edges are usually markedly rounded. Lower lateral edges are characteristically recurved, resulting in out-flaring basal corners of ears. The base is quite deeply concave. The broadest part is at mid-section or a little beyond, towards the tip. Average dimensions are: length 6.0 to 8.0 cm., maximum body width 2.3 to 3.2 cm., and base width 2.2 to 2.9 cm. Workmanship is fine. Initial and secondary shaping and thinning was by direct percussion. Initial flake scars are irregular. Pressure retouch of edges is not obvious. Essentially, vertical basal thinning was accomplished by the removal of either one or a series of irregular flakes. It should be noted that thinning scars on occasional specimens may be quite narrow and parallel to the point long-axis. Both the lower lateral edges and the basal concavity have been smoothed. [Illustration: _Golondrina_] At the type site, Golondrina points have been dated to about 8,000 years ago. Plainview points may be associated with them. Golondrina points have been found in north central, central, and southwest Texas and northeast Mexico. It is likely they will be identified in other parts of the broader Southwest. GYPSUM CAVE POINTS Gypsum Cave points were discovered together with the remains of extinct ground sloth in a cave near Las Vegas, Nevada. The over-all shape of Gypsum Cave points is elongate triangular. The straight upper lateral edges comprise virtually the entire length of specimens. The lower portion is characterized by a short stem formed by the abrupt sloping back of base edges from marked shoulders; the base is rounded. They are broadest from shoulder to shoulder. Average length of Gypsum Cave points is 5.0 to about 6.5 cm., and width about 3.0 cm. Flaking seems to have been produced by direct percussion. Initial flake scars are irregular. Secondary thinning of lateral edges is apparently absent. Stem edges were produced by multi-directional flaking. They are not smoothed. [Illustration: _Gypsum Cave_] The estimated age of Gypsum Cave points at the type site is from about 8,000 to 10,000 years. Points similar to these were found in a cave in the Manzano Mountains near Albuquerque and south of the Sandias. A specimen was recovered from the Lindenmeier Site in Colorado above the Folsom layer. LAKE MOHAVE POINTS Lake Mohave points were originally described from the Lake Mohave district of southeastern California. They were recovered from the surface and from ancient fossil beaches and terraces. [Illustration: _Lake Mohave_]
