SOME POINTERS:
Photos typically include their locations, so you can use locations as keywords too. You get more hits with shorter words, and fewer hits as you become increasingly specific with increasing numbers of keywords. It’s best to use singular rather than plural (eg “volcano” instead of “volcanoes”).
As some words are included in others (“salt” within “basalt,” for example) you might want to be more specific to avoid getting a bunch of irrelevant photos.
Or you can just scroll down and see the most recently added photos… Enjoy!

Download ImageTilted fault block, Nevada
Aerial view of Bare Mountain, a tilted fault block in western Nevada. Bare Mountain, just south of Beatty Nevada illustrates the defining structural style of Basin and Range extension: a tilted fault block. Its southern part consists of faulted Precambrian and Cambrian sedimentary rock. In this photo, one can see a large normal fault separating brown-colored Precambrian-Cambrian Wood Canyon Formation (below) faulted against lighter-colored Cambrian Carrara and Bonanza King Formations. The Carrara and Bonanza King formations show numerous smaller normal faults within them. (ID: IMG_5133)

Deflection of stream along San Andreas Fault
San Andreas fault at Wallace Creek in the Carrizo Plain, California, view towards the northeast. Note how the stream gully is abruptly deflected to the right about 150 meters. That deflection is caused by repeated right-lateral slip events (earthquakes) along the fault. (IMG_1404)

Download ImageBoulders on alluvial fan, California
Boulders on alluvial fan, Death Valley National Park, California. The canyon, at the apex of the fan, can be seen in the background. It is a wineglass canyon, formed by erosion of an actively rising mountain next to a fault zone. (IMG_1345)

Deflection of stream along San Andreas Fault
San Andreas fault at Wallace Creek in the Carrizo Plain, California, view towards the northeast. Note how the stream gully is abruptly deflected to the right about 10 meters. That deflection was caused by right-lateral slip events (earthquakes) on the fault. The deflection is not particularly great, because the stream gully is young. (IMG_1396)
