On August 7, 2015 President Barack Obama signed the Sawtooth National Recreation Area and Jerry Peak Wilderness Additions Act creating the Hemingway–Boulders (), Jim McClure–Jerry Peak (), and White Clouds () wilderness areas covering a combined of Sawtooth National Forest, Salmon-Challis National Forest, and Bureau of Land Management (BLM) land after it passed Congress on August 4, 2015. The Hemingway–Boulders Wilderness is entirely within SNRA, while all but of the White Clouds Wilderness is in the SNRA, with the rest managed by the BLM. The Jim McClure–Jerry Peak wilderness is entirely outside the administered area of Sawtooth National Forest, but partially within the area designated as Sawtooth National Forest and thus managed by Salmon-Challis National Forest and the BLM. The 2015 bill and previous versions were introduced by Republican Representative Mike Simpson, while prior bills had proposed to designate of wilderness as part of the controversial Central Idaho Economic Development and Recreation Act (CIEDRA). CIEDRA would have opened over adjacent to the new wilderness areas to motorized vehicle use, given of public land to local municipalities, and established a "no net loss" policy for motorized trails.
