The Pacific Crest Trail, like its better-known eastern cousin the i Trail, is a narrow corridor of wilderness set aside by an act of Congress (The National Trails System Act, to preserve a place where hikers can commune with nature.
I really like this picture for many reasons. The train in the background is a nice interesting background to look at. I like seeing the train from down below (a new perspective). The creek is a leading line to look above at the train.
