This map is very familiar to hikers and travelers of the San Gabriel Mountains, since is the identical map that is sold with every volume of
Trails of the Angeles - 100 Hike in the San Gabriels
by John W Robinson and Doug Christiansen (now on its 9th edition).
Includes;
Cucamonga Wilderness, San Gabriel Wilderness, Sheep Mountain Wilderness, Pleasant View Ridge and Magic Mountain Wilderness.
It shows Hiking Trails, mountain biking trails, cross Country Routes, all Ranger Stations, campgrounds and wilderness campsites, plus picnic areas. Many springs and streams (some good for trout fishing).
