Zone 64 covers the country between I-15 and the Wyoming border in extreme eastern Idaho, the country east of Henrys Lake including the western fringe of Yellowstone's neighbors. Elevations span from about 6,000 feet in the valleys to over 9,500 feet on the higher peaks. The country is lodgepole-dominated forest with aspen, subalpine fir, and meadow complexes—classic Yellowstone-edge habitat. The Henrys Lake Mountains anchor the western portion. Caribou-Targhee National Forest covers nearly all of the unit. Highway 20 and Highway 87 provide access; forest roads off them reach the high country. Island Park is the closest service town; West Yellowstone is just over the Montana line. Cell service is in towns. Elk hunting is the calling card—the Yellowstone-area herd uses this country, and the rut can produce quality bulls. Moose tags exist for the lucky few. The country is moderate-difficulty and reasonably accessible. Snow comes early at this elevation; October storms can lock the high country fast. Late-season hunts can be exceptional as elk concentrate on lower winter range.
