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!

The small holes in this rock are called tafoni –and they typically form through the growth of salt crystals that loosen the grains to create small pockets in the rock. Once the pocket forms, more seawater can collect to deposit more salt. It’s an example of a positive feedback loop. These rocks are part of the Eocene Coaledo Formation, Oregon. (140608-90)
