Over 600 projectile points have been collected during the testing of the four archaeological sites. Many of those have been found in dated contexts, allowing archaeologists to create a sequence of major styles of points from approximately A.D. 1 to A.D. 1400. The earliest points in the assemblage are from the Archaic Period. In general the points began with large corner-notched types that were likely used on darts/spears thrown with a spear thrower or atlatl. The next style (A.D. 700-900) is a medium size corner-notched point used with the first bows and arrows. This style attained its smallest size during the Mimbres Phase (A.D. 1000-1130). By the 1100s a side-notched style was in vogue, particularly with the new arrivals of the Socorro Ceramic Tradition. After 1200, almost all the arrow points are unnotched triangulars. This is true for the latest pueblo occupations.
