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!

Permian Coral from Tethys Ocean
This coral, and others like it, came from the ancient Tethys Ocean, which existed in the far western Pacific during the Permian. It is now found in limestones of Oregon’s accreted terranes. (110428-9)

Download ImageRed soil (laterite), Kauai
Laterite soil that has formed from tropical chemical weathering of basaltic lava flows, Kauai. These basalt flows are some of the oldest flows of the Hawaiian Islands.
Download ImagePliocene basaltic lava flows and lateritic soil
Pliocene basaltic lava flows exposed in the sides of Waimea Canyon, Kauai. These basalt flows are some of the oldest flows of the Hawaiian Islands. The red soil is laterite formed by tropical chemical weathering of the basalt bedrock. (110322-58)
