        We believe that it is important to support those who maintain trail infrastructure, those who foster a positive community and the human spirit, and those who protect our public land.



        The Arizona Trail is a few hundred yards from our Flagstaff office. The Arizona Trail Association is a fast-growing organization that has done an outstanding job with its volunteer program, Arizona Trail Stewards program, Seeds of Stewardship outreach program for children, and community involvement through it’s Gateway Communities program. We are proud to be a Business Parter of the ATA and to create the official app of the Arizona Trail.


        The Center for Biological Diversity has many program areas, including Public Lands. The CBD’s public lands program has protected countless species on millions of acres of federal land, and in the process protects our delicate ecosystems. The side benefits of protecting species habitat are tremendous. We joined the CBD’s Leadership Circle to support its mission.

        TRAIL CLUB

        The Maine Appalachian Trail Club maintains the northernmost 280 miles of the Appalachian Trail, from Grafton Notch to Katahdin. Guthook is a proud member of the Club, as well as a volunteer trail maintainer for about 8 miles of trail over Mt Abraham. The work done by MATC is, in Guthook’s opinion, some of the finest along the entire Appalachian Trail — a high bar, indeed!


        The Green Mountain Club is the 100+-year old organization that maintains and protects the Long Trail throughout Vermont, and works to “make the Vermont mountains play a larger part in the life of the people”. The GMC also maintains the Appalachian Trail and many other trails in the state, and is exemplary of fine work in protecting the recreational and natural resources of the Green Mountains. Guthook worked in the office of the Green Mountain Club for some of his formative years of getting to know how trail stewardship works, and Atlas Guides is now a proud Business Member of the Club.


        The Natural Resources Council of Maine is a nonprofit environmental advocacy group focusing on protecting Maine’s environment and public lands through sustainable use. Guthook has lived in Maine almost his entire life, and it was the state’s public lands and vast forests that originally made him a lover of the outdoors. We are proud to be supporting members of NRCM and to help the organization spread the word about some of their initiatives, including the recent success in achieving National Monument designation for the Katahdin Woods & Waters of Maine’s north woods.


        Warrior Expeditions supports combat veterans transitioning from their military service by participating in long distance outdoor expeditions. Warrior Hike participants thru-hike long trails in the U.S., such as the Pacific Crest Trail, Appalachian Trail, and Continental Divide Trail, among others. We have supported the Warrior Expeditions program by donating apps to Warrior Hike participants since the program began.

        People often ask me advice about what I use for navigation. Obviously that varies depending on where I’m going, but I typically start with downloading the Guthook app for the route I’m doing to my phone… These folks get it and they do a great job of helping the rest of us out. Thank you guys!

        I have been using Guthook’s Guides for thousands and thousands of miles and I am always amazed at what a powerful punch this tiny little app in my smart phone packs. What a fantastic tool to have in the backcountry or to help with planning purposes for future long distance hikes! It has been a go-to of mine for years now…and will continue to be as they update and expand!

        Thomas 'The Real Hiking Viking' Gathman

        I’ve been using New England Hiker this past year to follow obscure White Mountain trails and it’s saved my bacon more than once. While it doesn’t make the Appalachian Mountain Club’s Waterproof Map Set obsolete (batteries do die), it also includes lots of information that’s not on their maps. I always bring the New England Hiker App on my phone when I hike in the Whites, it’s really that useful.
