Geology Photos, Day 2

Evelyn's continuing the geology photos, and I can't think of a reason not to follow suit.

"Hey, since when is Pismo Beach in a cave?"

I blogged about this image before - some critter was doing a little bioturbation. If this burrow fills in with sediment and we were to then view this filled burrow in a soil profile, we might use the term "krotovina," which is a Russian word for a filled-in animal burrow. What a lovely word - perhaps Evelyn could use that for the next time she comes around to K for her geo words.
