Area 21 covers the foothills and broken country north of Cody between the Shoshone River and the Montana line, including the Polecat Bench, the Heart Mountain area, and the country running up toward Clark and the South Fork of the Clark's Fork. Elevations run from about 4,500 feet along the Shoshone River to 9,000 feet on the higher timbered ridges where the country starts to climb toward the Beartooth Plateau. The terrain is classic Bighorn Basin foothill: red and yellow sandstone breaks eroded into hoodoos and benches, sage and bunchgrass flats, mountain mahogany and limber pine in the rocky draws, and Douglas fir holding the cooler aspects. Heart Mountain itself is a famous geologic anomaly—a slab of older Paleozoic rock sitting on top of younger formations, the largest known landslide on Earth. The country glasses for miles. BLM, state trust, and private ranch share the country. WY-120 and county roads provide the access. Cody is the full-service town right there—gas, hotels, the Buffalo Bill Center, real grocery. Cell service is fair on WY-120 and degrades fast in the breaks. Mule deer dominate—this is classic broken-country mule deer habitat where the bucks live in the mahogany and juniper breaks year-round. Antelope work the open sage flats. Whitetail show up in the Shoshone River bottoms and irrigated fields. October archery is productive; rifle in November can produce mature bucks during the rut. Watch for the wind on Heart Mountain and the breaks above the Shoshone—it gets brutal, especially in late season.
