Shown above is El Capitan. This is the feature from Albert B. Dickas'  book  101 American Geo-Sites You've Gotta See  (Mountain Press) . We did a one day drive through of Yosemite and, just by luck, I photographed El Capitan. This place requires days to see. Needless to say, this was only a first trip.

GRANITE OUTCROP, ROUTE 120

We stopped at an overlook near the entrance to Yosemite. The rock was a pale grey, and had black streaks like water marks running down it. On closer examination the rock was granite! I thought it was some type of sedimentary. I was wrong. The only accurate reflectance spectrum could possibly come from the flat fragment (see below) I collected.  All of the sand grain fragments were too irregular for an accurate reading.
