The San Gabriel back country retains much of the natural beauty, if not the primitive wilderness of yesteryear… Thanks largely to the foresight and capable supervision of
the U.S. Forest Service and hundreds of volunteers. Picnic areas and campgrounds
have been constructed with minimum displacement of the natural setting.
