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!
Effects of flash flood
In 2004, a flash flood swept down Furnace Creek Wash in Death Valley National Park, tearing up the state highway and destroying the structures in and around the Zabriskie Point area. Such flash floods are relatively common, as most rainfall tends to run off into channels instead of soak into the ground. This particular flood was especially severe though because the rain fell in small area over a short amount of time.
