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!

Death Valley National Park sometimes has terrific spring wildflower displays if the conditions are right. That is, if there is plenty of rainfall in the winter months and then it warms up quickly in the spring. Notice how the flowers congregate in the channels on the alluvial fan. (M-13)

Download ImagePlaya scraper, Racetrack Playa, CA.
At Racetrack Playa, in the northern part of Death Valley National Park, numerous large rocks, such as this one, lie at the end of long trails, obviously carved out by the rock. The trails form very unusual patterns in some places. Most researchers now agree that the tracks form when sheets of ice on the playa begin to melt and drift, pushing the rocks in the process. M-05.

Aerial view of playa and tilted fault block, Nevada. Numerous dry lake beds, or playas, occupy the basins of the Basin and Range Province; they used to be substantial lakes during the wetter climates of the Pleistocene. These playas contain a record of the lakes’ highstands as a series of concentric rings, marking the ancient shorelines, called “strandlines”. (ID: M-07)
