Tide pooling

This morning, we headed to a nearby salt-and-pepper beach to poke around the lava-rock tide pools.

The beach is lovely, not too crowded, and has several large shade trees to sit under when the dark sand gets too hot.


Inside the tide pools, we found a variety of small fish species, invertebrates, and even a turtle or two.

In one pool, I found a little moray eel.


I found a couple of small freshwater springs feeding into the tide pools.  The fresh water is less dense than salt water, and so it stays near the surface and swirls around.  It also has different optical properties than salt water.  You can see the difference below.


Turnstones were foraging on the rocks as well.  Free divers were spearfishing just beyond the surf.  It was a great day to be on the beach.
