Located on the San Augustin Plain, Bat Cave is one of several rock shelters that overlook the southwestern edge of the plain. It was originally excavated by Herbert W. Dick in 1948 and 1950, and then again in 1981 and 1983 by Wirt Wills. The cave has a long occupation well into the early Holocene and abundant evidence of many activities and well-preserved artifacts. Famous for its well-preserved organic remains and stone tools, the site has directly dated maize samples that range from perhaps as old as 3700 b.p. to 2300 b.p. (Wills 1988).
