Zone 56 covers the country east of Pocatello in the Portneuf and Caribou ranges, including some of the most accessible elk hunting in southeastern Idaho. Elevations span from about 4,800 feet in the valleys to over 9,500 feet on the higher peaks. The country is sage and aspen-mahogany at lower elevations, transitioning into doug fir, lodgepole, and aspen at mid-slopes, with subalpine fir and meadow complexes on the upper benches. The Caribou Mountains add dramatic ridge country; the Portneuf River drainage anchors the western half. Caribou-Targhee NF and BLM cover the bulk of public ground, with significant private holdings in the valleys. I-15 and Highway 30 frame the unit; forest roads provide good access. Pocatello is the supply hub—gas, motels, restaurants, and a couple sporting goods shops. Cell service is in town and along the highways. The unit is famous among locals for its elk hunting, and the road access means pressure is real—weekend warriors descend from Pocatello and Idaho Falls. Mid-week hunts pay; hike past the first ridge from any road for solitude. Mule deer use the aspen-mahogany transitions. Late October weather brings real cold and the chance of snow.
