Zone 66 covers the Teton Range and Teton Valley on the west side of the Tetons in eastern Idaho. This is breathtaking country — the western slope of the Teton Range rises steeply from the valley floor around 6,000 feet to craggy peaks exceeding 12,000 feet, with the Grand Teton itself just across the state line in Wyoming. The valley floor (Teton Basin) is a mix of agricultural land, sagebrush flats, and cottonwood-lined creek bottoms. Mountain slopes carry aspen groves, Douglas fir, lodgepole pine, and Engelmann spruce, transitioning to subalpine meadows and alpine rock. The Jedediah Smith Wilderness encompasses much of the western Teton slope. The town of Driggs is the main service center — fuel, lodging, grocery stores, and several outfitter shops catering to hunters and outdoor recreationists. Forest roads on the Caribou-Targhee National Forest provide access to the lower and mid-elevation hunting areas, but the wilderness boundary limits motorized travel higher up. Highway 33 runs through Teton Valley and connects to Victor and Tetonia. Private land is concentrated on the valley floor, with national forest and wilderness making up the mountain slopes. Elk migrate through this zone seasonally, moving between summer range in the high Tetons and winter range in the valley. Early-season hunts catch elk higher, while late-season opportunities increase as snow pushes animals down. Cell service is good in Driggs and Victor but unreliable in the mountains. Weather can be harsh — snow accumulation at elevation is common by early October. Zone 66 in Teton Valley on the west slope of the Tetons operates under controlled hunt only for elk, and tags are competitive — the Yellowstone-area elk herds that migrate through make this a desirable destination. Wolf packs are established in the Teton Range and have impacted elk calf survival, contributing to IDFG management adjustments. The Jedediah Smith Wilderness covers much of the western Teton slope, prohibiting motorized access in the high country. Controlled hunt tags specify season and weapon type; there is no general-season elk opportunity. The zone is known for intercepting elk that migrate between summer range in the high Tetons (including animals that summer in Grand Teton National Park) and winter range in Teton Valley and beyond. The migration timing is weather-dependent — early snow pushes elk down from the high country into huntable terrain on the national forest and valley-edge private land. Mule deer are available under general season in the sage-and-aspen foothills. The proximity to Driggs and the Jackson Hole area provides excellent staging and services.
