Mary Caperton Morton is a freelance science and travel writer specializing in geophysics, hydrology, and mountaineering. Her book, Aerial Geology: A High Altitude Tour of North America’s Spectacular Volcanoes, Canyons, Glaciers, Lakes, Craters and Peaks, was published by Timber Press in 2017. In her 13 years as a seasonally nomadic freelancer, she has hiked in all 50 states; climbed hundreds of mountains; and written for numerous publications including Eos, Earth, Science News, The Last Word on Nothing, and her blog, Travels with the Blonde Coyote. When she’s not at the keyboard, she’s outside, exploring the Sierras from her home base in the foothills of Sequoia National Forest in California.
