Description of Green Trails Map Mt. Hood, OR Climbing Quarter Fold The essential map if you are attempting to summit Mt. Hood. Green Trails, Inc founded in 1973, publishes over 125 topographic recreation map titles for the most spectacular mountain and beach areas of Washington and Oregon's Cascade Mountains and Washington's Olympic Peninsula. Green Trails maps show the most current trail, road, and access information to national forests, national parks, state and local parks, and other public lands in the most clear, compact, and convenient format and scale available. Green Trails maps have been the Northwest's first choice for hiking, backpacking, walking, climbing, mountaineering, cross-country skiing, mountain biking, fishing, horseback riding, and hunting for 30 years. Green Trails Maps are used by Cascade Mountain Rescue because they show trails that other maps don't. Special MapPacks covering the Seattle Mountaineer's "Hikes with Children" guide books make them a valuable source for parents. Smaller and easier to manage than the USGS maps that they are based on, they are indispensable for Boy Scouts, Girl Scouts, birdwatchers, wildlife students, orienteerers and Global Positioning System (GPS) enthusiasts.
