About Ray Watts

Raymond D Watts, PhD, is a geophysicist and geographer who retired in 2010 after a 40 year research career. He has worked on lunar exploration, glaciology, nuclear waste management, climate change, distribution of roads of the U.S., and ecological effects of roads. Most of his research career was at the U.S. Geological Survey in Colorado. While studying road distribution, he developed ways to measure the amount of space between roads and became concerned about the inexorable loss of this American resource.
