VASQUEZ ROCKS STATE PARK 34.49N, 118.32W
The link is to a website describing the
park. It is very nicely done.
All photographs by C. or
F. Lindgren
You usually have to check before going
into the park to see if any filming is being done there that
day. What famous science fiction character was killed on
this rock outcrop while trying to save the world?

The Vasquez rocks are a fanglomerate. I'd never heard of
this rock before. It's a sedimentary rock formed from the
deposits in an alluvial fan. As water comes off of a
mountain and empties into a valley in the desert, it drops
whatever it is carrying in a "dry" delta. As a result, the
layers can be composed of fine sand, sand with some rocks,
or huge boulders. Imagine the speed and amount of water that
must have been required to carry the boulder I am
photographing in the image above! |
This image shows a quieter flow! |
