Photograph of a group of more than 100 pelicans roosting on a rocky shore 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." Hundreds of pelicans in the background on the water or shore.
