California Sea Lion

This California Sea Lion was basking solo on the beach at South Jetty in Fort Stevens State Park on Saturday morning. At first my we thought it may be injured or dead, but then we saw it looking around and acting alright.
We approached it slowly making sure not to get too close. When we got a little too close for its comfort, it raised up on its front flippers and held its head up to the sky. I assume this was an attempt to look threatening. It convinced me. We took a few pictures and then backed off.
