Margaret and daughter Leslie, looking for fish, 1961

Her first hiking guide to trails in Idaho was inspired by difficulties finding good hikes for her children near the family cabin.  Margaret and her husband, young children and friends built the cabin themselves by hand. But hiking in the area proved a challenge because if the access road wasn’t full of boulders and deep ruts, the trailhead could not be found, or the trail was hard to follow. When Margaret saw a guidebook to trails in the Washington Cascades she realized a trail guide was needed for the Sawtooth National Recreation Area (SNRA) and decided to write one.  From Frostline kits, she sewed the tents, down jackets and sleeping bags she and her family needed for the hiking and backpacking trips they took to gather details for the book. In writing her hiking guidebooks she has had many adventures, from encountering rapids under an overhang on the Middle Fork of the Salmon River trail to coming face to face with a bear with frosted fur in the Lemhis.  

Margaret began hiking at about the age of three from her grandfather’s cabin in the Sierras.  She earned her BA in biology in 1956 from Stanford University, and earned an Idaho teaching credential in 1973 after taking classes at the College of Idaho. She then did temporary and substitute teaching and wrote hiking guidebooks until she got a contract to write a book on mountains. Mountains: a Natural History and Hiking Guide was published by John Wiley & Sons in 1989. Two years later Wiley published Forest Fires: An Introduction to Fire Behavior, Fire Management, Firefighting and Prevention. That book won first place in the Northwest Outdoor Writer's Association annual contest.

“I guess I’ve always loved being out in the mountains and I kind of felt like I wanted to give back what the mountains had given me to give others in a broader way.” -- Margaret Fuller’s comment about receiving the award which is the highest distinction given by the Idaho Conservation League for dedicated passion and efforts to preserve the environment." – Brigid Leake,  “Margaret Fuller, One Who Gives Back”, Idaho Conservation League newsletter, July 2010
