Area 13 takes in the western flank of the Bighorn Mountains between Ten Sleep and Hyattville, climbing from the Bighorn Basin floor up over the high crest of the range. Elevations run from about 4,500 feet in Ten Sleep Canyon's mouth to over 12,000 feet on the high Bighorn peaks. Ten Sleep Canyon itself is one of the most dramatic mountain-front canyons in Wyoming—5,000 feet of vertical between the basin and the crest, layered limestone walls, and US-16 winding up past climbing routes that bring international visitors. Vegetation stratifies hard with elevation: sage, juniper, and mountain mahogany on the foothills; ponderosa, Douglas fir, and aspen at mid-slope; lodgepole and spruce-fir in the timber band; and alpine meadow and rock above 10,000 feet. Paint Rock Creek, Tensleep Creek, and Medicine Lodge Creek drain the country and hold reliable water. Bighorn National Forest covers the upper country, with BLM, state trust, and private ranch land filling in the lower foothills. US-16 over Powder River Pass is the paved spine; forest roads off it climb into the timber. Ten Sleep, Worland, and Hyattville are local; Worland has the most services. Cell service drops past Ten Sleep and stays gone. Quality elk in the timber, mule deer in the foothill mahogany breaks and the high parks, antelope on the basin sage. Moderate pressure during rifle—nothing like the east slope crowds out of Buffalo. The Cloud Peak Wilderness boundary skirts the high country up north. October weather can swing from t-shirt warm in the canyon to a foot of snow on top in 12 hours; bring chains for the dirt and a real sleeping bag.
