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!

This photo shows wineglass canyons and a straight and abrupt edge to the mountain front. Black Mountains, Death Valley National Park, CA.
Download ImageWineglass Canyon, Wasatch FZ ,Utah
Wineglass Canyon and rrban development along Wasatch fault zone, Salt Lake City, Utah. Wineglass Canyons indicate recent fault movement. (SrA-26)
Download ImageW edge of Colorado Plateau
Aerial view of Cedar City, Utah and Hurricane Fault. The normal fault marks the western edge of the Colorado Plateau and eastern edge of the Basin and Range. (ID: SrA-25)
Download Imagefault-controlled mtn front, Teton Range, WY
The linear and abrupt edge of the Teton Range in Wyoming indicates recent uplift along the Teton normal fault. Grand Teton National Park, Wyoming. (SrA-22).
Download ImageFault-controlled mtn front, Death Valley (vertical)
The Black Mountains of Death Valley National Park, California, are bound on their west side by the Black Mountains fault, an oblique- normal fault that has been active in the recent past. (SrA-13)
Download ImageLandslide scar and drowned trees
Landslide scar and drowned trees, Earthquake Lake, Montana. The landslide blocked the Madison River to make the lake and drown the trees (SrA-19)
Download ImageTriangular facets, SW Montana
Triangular facets on east front of Tendoy Range, SW Montana. Triangular facets indicate recent uplift on faults. (SrA-20).
Download ImageFault scarp on alluvial fan
Fault scarp on Hanaupah alluvial fan, Death Valley National Park, California. (SrA-11)
Download ImageOwens Valley fault scarp, CA.
Fault scarp: Owens Valley fault, at base of Sierra Nevada, California. Scarp has formed over several earthquakes, most recently in 1872. (SrA-16)
Download ImageOwens Valley fault scarp, CA.
Owens Valley fault and Sierra Nevada Range, California. Scarp has formed over several earthquakes, most recently in 1872. (SrA-17)
Download ImageFaulted edge of Death Valley, (vertical)
In Death Valley National Park, California, the Black Mountains rise abruptly along a fault zone, shown in this aerial photo. Note the alluvial fans that grade into the Salt pan along the front. (SrA-14)
Download ImageOwens Valley and Sierra Nevada
The Sierra Nevada rises along a series of normal and strike-slip faults in the Owens Valley of California to mark the eastern edge of the Sierra Nevada. This fault last slipped during the M7.4 Owens Valley Earthquake of 1872. Note the cinder cone–several recent basaltic lava flows have erupted along the trace of the fault. (SrA-15).
Download ImageFaulted colluvium (vertical)
Faulting in colluvium along North Branch of the San Andreas fault, San Bernardino Mtns. (ID: SrA-05)
Download ImageUplifted shorelines, SE California.
Uplifted shorelines, Panamint Valley, California. (SrA-12)
Download ImageFault scarp and alluvial fan
Fault scarp and alluvial fan, Death Valley National Park, California. (SrA-10)
Download ImageWineglass Canyon, Death Valley, CA.
Wineglass Canyon and Black Mountains frontal fault zone, Death Valley National Park, California. (SrA-08)
Download ImageWineglass Canyon, Death Valley, CA.
Aerial view of wineglass Canyons and fault-controlled mountain front, Death Valley National Park, California. Wineglass canyons, named for their steep, narrow mouths and broader, gentler upper reaches, (they look a little like wineglasses) indicate recent uplift activity on the bounding fault zone. Faulting continually uplifts the front of the canyon, so that erosion does not have time to widen it. Consequently, the canyon mouth retains a steep and narrow shape. (ID: SrA-06)
Download ImageTrench with shoring (vertical)
Geologist working in a trench across the San Andreas fault near Wrightwood, California. (SrA-04)
Download ImageShale outcrop, northern Montana
Shale of the Proterozoic Snowslip Formation (Belt Supergroup) in Glacier National Park, Montana. (Sed-57)
