Based in Summit County, Colorado, Fritz Sperry has made the mountains surrounding the Colorado Front Range his playground. Released a few years ago, but still entirely relevant, Making Turns in Colorado's Front Range Volume 1 is a brilliant guidebook for ski touring that covers terrain south of Interstate 70.
To make sure you're not feeling stuck on the same routes weekend after weekend, Fritz includes 71 routes on 36 peaks with five 14ers in 5 counties.
Each route also includes access, 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!
