Save Our Snow, by Dr. Mark Williams

Water security is critical to the economy of Colorado and other western states. Snowmelt runoff from high-elevation mountains provides most of the usable water in Colorado. Mark Williams, professor of geography and INSTAAR Fellow, explains why mountains are "water towers” while focusing on how our water security is threatened by a variety of factors, including climate change, the mountain pine beetle epidemic, and hydraulic fracturing for natural gas.
