Palm Canyon ~ Kofa National Wildlife Refuge - Yuma, AZ

An area of rugged beauty, Palm Canyon is the only place in Arizona where native palm trees, California Fan Palms, can be found. These unique plants are probably the descendants of palms growing in this region during the last periods of North American glaciation. Some botanists theorize that the trees gradually spread into these canyons and other protected niches as the climate warmed to desert conditions. Other researchers have suggested that the trees may have been spread from other palm groves by birds or coyotes carrying seeds in their digestive tracts. Recorded January 17, 2021.
