Pacific Crest Trail
The route was first explored in the 1930s by teams from the YMCA. Clinton Clarke and Warren Rogers lobbied the federal government to provide a corridor. The PCT was eventually designated one of the first scenic trails in the National Trails System authorized by Congress in 1968, and was dedicated in 1993.
