Hiking the San Diego and Arizona Eastern Railway Fan Palm Oasis near Agua Caliente Dos Cabezas Junction and Dolomite Mine First view of Corrizo Gorge Hiking along the tracks of the San Diego and Arizona Eastern - the “Impossible Railway” Some really stunning mica deposits along the railway line. The first tunnel Redwood beams support the tunnel walls - each one the size of a tree. A large California Fan Palm grove at the bottom of the gorge. Smoke and soot on the ceiling from countless passing trains. Spotted along the way: Huell Howser's lunch spot from his trip to the Corrizo Gorge trestle. A young rattlesnake hiding beneath the rails. A strange succulent we spotted in several places along the route.
