When Kenneth Wright went hiking through Mesa Verde National Park with his wife, he didn't expect to be pulled into a research project on ancient waterworks. But he was. It started with a structure called the Morefield Mound. The use of this structure had been debated by scientists all over the world. Using the science of paleohydrology--the study of water use and water handling by ancient people--Wright and his researchers were able to prove that this and other similar sights in the park were in fact reservoirs for ancient peoples who lived in Mesa Verde. This enthralling book meticulously recounts the intelligence, the ingenuity, and the forethought of our ancestors.
