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!
Wave breaking on sandstone berm, Oregon (vertical)
Wave breaking on sandstone berm, at Shoreacres State Park, Oregon. Cross-bedded sandstone in foreground and seacliffs behind is part of the Eocene Coaledo Formation. Note the angular unconformity between those tilted rocks and the uplifted marine terrace. (5D-8922)

Seastacks, which mark former positions of the coastline, stand up out of the surf near Bandon, Oregon. (5D-9218)

Ash Flow tuff, Crater Lake, (vertical)
Ash flow tuff from caldera-forming eruption of Mt. Mazama to form Crater Lake about 7700 years ago, Crater Lake National Park, Oregon. The ash flow deposits erode into Pinnacles. The pinnacles are more resistant to erosion than the surrounding rock because of precipitation of minerals from gas escaping from the ash flow. (5D-8664)
