There is a large colony of Elephant Seals that live at the park. It's a bit of a trek through the sand dunes to get to the area where the seals are, but it is worth it. (It's also worth doing the walk in sandals, unless of course you enjoy pouring half the beach out of your shoes when you are done.)
While we were watching these guys, there were a whole bunch of them flipping sand onto themselves.
I also noticed a pattern in how they itched themselves. Every time any of them had an itch, they would first lift their flipper into the air, where it would stand for a little while. Then they would do the Queen's wave, followed by a good scratch.
But my favorite bit was seeing their tracks. It kind of looked like giant lizard tracks.
Right now there are only juvenile seals out there. But come winter, the large males (with giant, silly noses) will be out there battling for a harem of ladies. I'm hoping we can go out and watch.
Bonus: Elephant Seals fast while they are on land, so they don't foul up their living area. They smell a-ok. The California Seal Lions are another story....
