Geo 365: April 24, Day 114: Sand-Rock Interface

Water running off the tidepool platform combines with water from a small stream and more seeping out of the hillside to carve a moat around the rock. This area is not as heavily colonized by sea life; it's frequently buried in sand. They can survive a little of that, for short period of time, but burial will eventually kill them off.
