Section 2301 of the Omnibus Public Lands Management Act of 2009, section 2301 renamed the area as the Nelson Snake River Birds of Prey National Conservation Area in recognition of the contributions of Morley Nelson, a raptor expert and advocate and a leading proponent of the original creation of the National Conservation Area.
About 14,000 years ago, as glaciers receded from the last ice age, the 20000sqmi Lake Bonneville crested at Red Rock Pass, Idaho, creating what is known as the Bonneville Flood. As soft soils eroded at the pass, the lake poured into the volcanic plain of the Snake River and its canyons. Today, visitors to the Snake River area can explore the house-size boulders, box canyons, and other evidence left behind by the tremendous flood. At Swan Falls (now Swan Falls Dam), peak discharge of the flood was an astounding 33 million cubic feet/second.
