Indigenous Agave Use in the Ocampo Caves Vicinity, Tamaulipas, Mexico.

The symbiotic relationship between people and the genus Agave spans millennia and a vast geographical area encompassing Mexico, the southwestern United States, and the Texas borderlands. In the early 1950s, Richard MacNeish's investigations in Tamaulipas yielded evidence of past agave use in the mountains of northeastern Mexico. Excavations in the Ocampo Caves revealed 9,000 years of sporadic occupations by hunter-gatherers, mixed forager-farmers, and finally, periodic visits by residents of nearby agricultural villages. Although these discoveries are incompletely published--and existing publications largely underemphasize the range of utilized wild resources in favor of domesticated maize, beans, and squash--agave is among the wild plant taxa most often mentioned in use throughout the Holocene. Unpublished field notes, curated plant assemblages recovered during MacNeish's excavations, and data from recent archaeological survey complement the published literature to explore the role of this prominent plant in this important archaeological region.
