Ann Marie Brown made her first solo trip to Yosemite at age 22. Like many first-time visitors, she was immediately inspired by the Valley’s sheer granite walls and shimmering waterfalls. Parking her car at the first trailhead she saw, she set off on the Four-Mile Trail. Carrying nothing but a water bottle, she intended to hike only a short distance but was so wowed by the scenery that she kept on walking. Two hours later she found herself at Glacier Point, considered by many to be the grandest viewpoint in the West. Scanning the scene, she noticed tourists dressed in everything from high heels to a nun’s habit, and realized that she could have driven to Glacier Point instead of walking. Ann Marie vowed she’d never again go hiking without a map.More than two decades later, Ann Marie has gained substantially more outdoor savvy and is a dedicated California outdoorswoman. She hikes, camps, and bikes more than 150 days each year. She is the author of 13 Moon guides, including several outdoors titles, like 101 Great Hikes San Francisco Bay Area, and is the co-author of Moon California Hiking with Tom Stienstra. Her work has also appeared in Sunset, VIA, and California magazines.
