AB: Ancient Maya structures and the ambient spaces around them are under-used barometers of soil development. The Piedras Negras region in northwestern Guatemala is uniquely suited to such research because unlike many other parts of the Maya Lowlands it was abandoned after about AD 850-900, and never substantially disturbed by humans thereafter. Recently excavated rural sites near Piedras Negras show that upland soils developed over the last 1100-1200 years are quite thin, and raise the issue of how deep the original upland soils were that were encountered by the first farmers.
