The University of Arizona Cooperative Extension, SAHRA, and Arizona State Parks jointly created this program on the key role of water in the history and evolution of Kartchner Caverns and the San Pedro River Basin.

This program introduces the hydrology of Kartchner Caverns: how water created the cave spaces and formations; how it continues to shape the caverns today; and the water cycle of the Upper San Pedro Basin. Please select a viewing preference below to begin, or click here to purchase the DVD
