Zone 57 covers the country southeast of Idaho Falls in the Caribou Mountains and the Snake River Range foothills. Elevations span from about 5,000 feet in the valleys to over 9,800 feet on the higher peaks. The country is sage and aspen-mahogany at lower elevations, transitioning into doug fir, aspen, and lodgepole at mid-slopes, with subalpine fir on the high country. The Caribou Mountains and the Webster Range produce some of the most underrated elk hunting in southeastern Idaho. Caribou-Targhee NF, BLM, and state ground cover the bulk of public land. Highway 26 and various county and forest roads provide access. Idaho Falls is the metro hub; Swan Valley, Palisades, and Soda Springs are smaller supply options. Cell service is in towns. Elk hunting is the headline—the unit produces quality bulls in the high timber. Mule deer use the aspen-mahogany. The country is moderate-difficulty with good road access on the main drainages, but the side drainages get steep fast. Pressure is real because of Idaho Falls proximity; mid-week hunts and willingness to climb is how you find space. Late September can already feel like winter at elevation.
