Charcos

GENERAL DESCRIPTION : A small to medium sized point that has base to corner notches. After some use or re-sharpening, it has a squared to pointed barb on one side and a notch in the edge of the blade on the other side. The stem may be straight to slightly expanding and has straight to slightly convex basal edge. Basal corners are usually rounded. This type has been divided into three varieties : Charcos un-notched, Charcos single notched { in the blade edge } and Charcos double notched. The Charcos point was named by Lorraine Heartfield { 1975 : 136 } for the Desierto de Charcos de risa in Mexico.

AGE AND CULTURE : Thought to be a late Archaic type, possibly extending into later times, having a probable date of 500 B.C. to A.D. 250.

DISTRIBUTION : Full range of distribution not determined. The Charcos has been found in numbers in Northern Mexico south of Big bend of the Rio Grande and sparsely on the Texas side of the river
