Zone 73 sits in the extreme northeast corner of Idaho around Henry's Lake and the Continental Divide, where Idaho, Montana, and Yellowstone National Park converge. The terrain is a mix of high-elevation plateaus, rolling timbered hills, and open meadows between roughly 6,400 and 9,500 feet. Henry's Lake itself is a shallow, natural lake surrounded by sagebrush flats and wet meadows. The surrounding mountains — the Henrys Lake Mountains and Centennial Mountains — carry lodgepole pine, Douglas fir, and aspen on their slopes, with open parks and meadows on ridgetops. The Continental Divide forms the Montana border and the northern boundary. This zone benefits from Yellowstone-area elk herds that move seasonally across the landscape. Caribou-Targhee National Forest and BLM make up most of the public land, with private ranches in the valley bottoms. Highway 87 and Highway 20 provide the main access; forest roads branch into the surrounding hills. Island Park, about 20 minutes south, offers lodging, fuel, and restaurants; West Yellowstone (Montana) is close and has more options. Cell service is available along the highways but spotty in the timber. At this elevation, winter arrives early — expect freezing nights by mid-September and real snowstorms by October. The high plateau can be brutally windy and cold, so dress for it. Late-season hunts here can be outstanding as elk concentrate on lower-elevation winter range, but road conditions can deteriorate rapidly. Zone 73 sits at the north end of the Henry's Lake drainage near the Continental Divide where Idaho, Montana, and Yellowstone National Park converge — a small, high-altitude zone defined by its border-country position and the management headaches that come with it. Elevations range from about 6,400 feet on Henry's Lake to 9,500 feet on the surrounding peaks of the Henry's Lake Mountains and the Centennial Range. The terrain is a mix of sagebrush flats, willow-choked creek bottoms, and timbered mountain slopes of Douglas fir, lodgepole, and spruce-fir. Henry's Lake itself is a shallow, highly productive lake famous for trophy trout, and the surrounding wetlands and sage flats create a wildlife crossroads. The zone's proximity to Yellowstone National Park is the defining management issue: elk, moose, and other wildlife cross freely between the park, Montana, and Idaho, creating a jurisdictional puzzle that frustrates biologists and hunters alike. US-20 and US-87 provide highway access along the Continental Divide corridor between West Yellowstone and Idaho Falls. The town of Island Park, strung along US-20, offers gas, lodging, and restaurants oriented toward the tourist and angling trade. West Yellowstone is just across the Montana border with full services. Cell service works along the highways. The Yellowstone border issue shapes everything about hunting here: animals that summer in the park migrate into huntable Idaho ground in fall, but the timing is weather-dependent and the park boundary is a hard line. Hunters need to know exactly where the state and park boundaries fall — GPS is essential, not optional. Moose, once abundant in this zone, have declined significantly due to a combination of predation, habitat changes, and disease, and permit availability reflects that decline. Elk opportunity depends on the specific controlled hunt drawn and the migration timing. The high altitude means winter arrives early — snow by October is normal, and temperatures drop sharply once the sun sets. The combination of border-zone politics, controlled hunts, and weather variability makes Zone 73 a complex hunt to plan, but the country is beautiful and the proximity to Yellowstone's wildlife reservoir means the animals are there if the timing cooperates.
