Based in Summit County, Colorado, Fritz Sperry has made the mountains surrounding the Colorado Front Range his playground. Making Turns in the Ten Mile & Mosquito Range is a brilliant guidebook for ski touring that covers terrain between Interstate 70 and Highway 285.
This terrain is chock-full of great lines and big peaks, including six 14ers such as Lincoln, Quandary, Democrat and Sherman, and Fritz includes over 300 pages of details including the Breckenridge Ski Resort sidecountry.
Each route also includes topo maps, access information, directions, aspect and best season to ski.
Disclaimer: no guide book will tell you when it's safe to ski these rad lines, so be smart, take an avy course, hire a guide, and pay attention to all the signs in the backcountry that will ultimately keep you alive!
