Photograph of a group of more than 50 pelicans roosting on a dry desolate butte of the Salton Sea, California, ca.1910. This is "one of the dry desolate buttes of the Salton Basin, now [ca.1910] converted into an island by the waters of the overflow [from heavy runoff breaking the levee of the then under-construction Imperial Canal at the Colorado River]. In a few weeks after its being surrounded by water it became the nesting grounds of tens of thousands of pelicans." Dozens of pelicans are flying over the butte (blurred). The lake is visible at right and in the background.
