Abstract In northeastern Bolivia, on savanna lands subject to seasonal inundation, there are many thousands of pre-Spanish earthworks including drained fields, causeways, mounds, canals, and circular ditches. Additional information is presented here on the nature, quantity, distribution, purposes, and antiquity of these only recently described earthworks, along with a brief review of similar features in South America and elsewhere.
