Swatches of marine algae on a rocky bed look like abstract art. The featured image for this post is unique because the algal patches that give it the abstract quality live on a roadbed carved into a rocky headland. The bed is exposed only at low tide. Being smooth, flat, and nearly level, it’s a rare surface in the rocky intertidal.
The gallery below gives intertidal sand a chance to show off its abstract side next to its sister, the rocky intertidal.
These images are all from spring 2016 on a mile-long reach of northern Oregon shore.
