As a SoCal resident, I visit Anza-Borrego at least once a year to explore the sandstone Slot canyon and surrounding desert, keeping an eye out for animals like chuckwalla lizards and bighorn sheep. Despite its incredibly dry environment (the park averages just four to eight inches of rain a year, and summertime temps routinely hit the hundreds), Anza-Borrego teems with life and opportunities to explore one of the nation's most unique ecosystems.
