Ten thousand years ago, the California condoras shadow raced across the rock faces of canyon walls throughout the Southwest, but, over time, the majestic condor disappeared from this landaseemingly forever. Last seen in northern Arizona in 1924, the California condor was on the brink of extinction. In the early 1980s, scientists documented only twenty-two condors remaining in the wild, all in California. Thanks to a successful captive-breeding program, their numbers have increased dramatically, and dozens now fly free over northern Arizona and southern Utah.
