In 1908, two biologists from UC Berkeley's Museum of Vertebrate Zoology — Harry Swarth and Joseph Grinnell — became the first scientists to formally document what they found in a canyon cutting into the north face of the Santa Rosa Mountains above the Coachella Valley. The canyon dropped nearly a mile and a half in a little over eight miles, compressing multiple ecological zones into a vertical space that functioned like a biological elevator. More than a century later, researchers are still finding things in Deep Canyon that exist nowhere else on earth.

In 2010, a study of 35 wasp species at Deep Canyon's Agave Hill revealed four new species, two of which — Odontophotopsis hammetti and Sphaeropthalma mankelli — are known to exist nowhere else on earth. The canyon hosts ongoing studies of endemic and rare species across multiple ...
