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!

Badlands erosion, Death Valley National Park, California. Furnace Creek Formation (ID # WE-07)
Download ImageArch eroded from fins, SE Utah
Arch and fins in background, Arches NP, Utah. (ID # WE-03)
Download ImageButtress Unconformity, northern Arizona
In buttress unconformities, the younger material
is deposited against the older material, resulting in the apparent truncation of the younger rock. On closer inspection, however, one can see erosional features along the contact to indicate its depositional
origin. (ID SrU-25)
Sandstone Arch, SE Utah
Arch (Wilson Arch) of Jurassic Navajo Sandstone, SE Utah. (ID WE-04)
Download ImageSandstone Fins
Sandstone fins–from erosion along joint surfaces, Arches NP, Utah (ID WE-02)

Delicate Arch, made of Jurassic Navajo Sandstone. Arches National Park, Utah. (ID # WE-01)
Download ImageAngular unconformity, Death Valley, CA.
This unconformity shows 4 Ma Funeral basalt overlying Artist Drive Fm (left) faulted against tilted Furnace Creek Fm (right). The 1920’s era mining camp of Ryan sits on the hills just below the unconformity. This area has been the site of underground and strip mining of borate minerals. (Image ID# SrU-23)
