Young lizard already missing part of its tail.
Juvenile or patternless adult. I'm not to good with identifying these guys. I saw the blotch in a quick glimpse though. Didn't get a picture of it but I saw it.

The common side-blotched lizard (Uta stansburiana) is a species of side-blotched lizard found on the Pacific Coast of North America. It is notable for having a unique form of polymorphism wherein each of the three different male morphs utilizes a different strategy in acquiring mates. The three morphs compete against each other following a pattern of rock, paper, scissors, where one morph has advantages over another but is outcompeted by the third.
