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)

Basaltic dikes intruding previously erupted Pliocene basalt flows, Kauai, Hawaii. These dikes are feeder dikes for younger flows. (110323-53)

Sandy beach, Kauai.
Sandy beach at north end of Na Pali Coast, Kauai, Hawaii. (110323-26)
Download ImageErosion of Pliocene basalt flows, Kauai
Erosion of Pliocene basalt flows of the Na Pali sea cliffs, Kauai. These lavas belong to the 5.1 Ma (lower Pliocene) Napali Member of the Waimea Basalt, the oldest lavas of the Hawaiian Islands. (110322-60)
Download ImageRed soil (laterite), Kauai (vertical)
Red soil (laterite) that has formed from chemical weathering of basaltic lava flows, Kauai, Hawaii. Basaltic bedrock crops out over the bottom half of the photo. (110322-19)
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)

Wailua Falls plunges over basalt flows, Kauai, Hawaii (110321-70)

Download ImageSand flows on sand dune, Oregon. (vertical).
Sand flows on steep side of sand dune. Note that some flows consist of multiple deposits. These flows are driven purely by gravity (mass wasting) and exhibit the same morphology as unconfined debris flows and mudflows. (110306-37)
Download ImageOregon Coast and headlands
Surf and headlands on Oregon Coast, between Florence and Newport. (110312-55hdr)
Download ImageMagmatic flow foliation in granitic rock
Magmatic flow foliation defined by large orthoclase crystals in granitic rock. Photo is about 50cm across. (110131-11)
