	title = {Two Preceramic Sites in the Highlands of Guatemala},
	year = {1973},
	address = {Burnaby},
	abstract = {Test excavations were carried out in 1969 and 1972 at two small sites each located in open meadows within a cloud forest on a mountain ridge at about 10,000 feet elevation. A quantity of flakes and a small number of artifacts including scrapers, retouched flakes, and a small biface but no projectile points were recovered from weathered colluvial deposits. At one site, La Piedra del Coyote, the lithic assemblage underlies a horizon of Late Classic pottery. At the other site, Los Tapiales, the lithic assemblage has been dated at 7550 +/- 150 years B.P. (Gak-2769).},
