Located within the Pacific Flyway, Sonny Bono Salton Sea National Wildlife Refuge in California is an important resting and nesting place for migrating birds. With a fascinating history and an uncertain future, the refuge takes visitors 227 feet below sea level to witness a stunning desert landscape. It can get extremely hot in August, but well prepared adventurers can still find gulls and migrating shorebirds. Photo by Sarah Chah (http://ift.tt/18oFfjl).
