Blunt-nosed Leopard Lizard (Gambelia sila)
Blunt-nosed Leopard Lizards are an endangered species, primarily due to habitat destruction. They used to range far and wide across the grasslands of California's San Joaquin Valley, but nearly all of their original habitat has been converted to agriculture or rangeland and made inhospitable for these lizards.

I had searched for this species unsuccessfully at least six times, before finally coming across this beautiful specimen.
