Overview
Area 111 spreads north and east of Rawlins across open sage flats, sagebrush steppe, and the rugged Seminoe and Ferris Mountains, bounded by Interstate 80, U.S. 287, and the North Platte River drainage below Seminoe and Pathfinder reservoirs. It is classic south-central Wyoming pronghorn ground — vast public BLM broken up by private ranch and the notorious Union Pacific checkerboard along the I-80/railroad corridor. Mule deer hold in the rougher breaks and mountain foothills, and a scattering of elk uses the Seminoe and Ferris high country.
Terrain
Rolling sage basins and high-desert flats rise into the isolated Seminoe Mountains and the steep, timbered Ferris Mountains, dropping to the North Platte River and its chain of reservoirs.
Cover: Big sagebrush and greasewood steppe on the flats, grassy parks and scattered juniper in the breaks, with limber pine, aspen, and Douglas-fir on the higher Ferris and Seminoe slopes.
Landmarks: Seminoe Reservoir · Ferris Mountains · Seminoe Mountains · North Platte River / Miracle Mile · Pathfinder Reservoir · Great Divide Basin edge
Access
Roughly two-thirds public (about 51% BLM, 12% state, plus small USFS/other) but heavily interrupted by private ranch and the Union Pacific land-grant checkerboard along the I-80 and railroad corridor near Rawlins, where odd-numbered sections alternate public and private. Corner-crossing between diagonal public sections is a live legal issue here — know section lines before stepping across. Some private is enrolled in WGFD Hunter Management / walk-in access.
Managers: BLM, private ranch, WY state trust, USFS
Access points: Rawlins (I-80 / U.S. 287 junction) · Seminoe Road / County Road 351 to Seminoe State Park · BLM two-tracks off U.S. 287 north of Rawlins · Ferris Mountains WSA access roads · Miracle Mile / North Platte river access
Species notes
Pronghorn
abundant qualityThe marquee species — dense pronghorn herds range the sage basins across the unit, a popular limited-quota antelope area with generally good draw odds and solid public access.
- →Glass from high sage benches at first and last light and cover country by truck between glassing points
- →Use the BLM checkerboard map to plan legal stalks and avoid trespass on interlocked private sections
- →Waterholes, stock tanks, and reservoir margins concentrate bucks in warm early-season weather
- →Spot-and-stalk with terrain — use cuts, draws, and rises to close on bedded bucks in open country
Mule Deer
common opportunityMule deer inhabit the rougher breaks, draws, and the Seminoe/Ferris foothills; bucks take scouting to find but the country holds mature deer in pockets away from roads.
- →Hunt the timbered and brushy edges of the Seminoe and Ferris Mountains where deer escape open-country pressure
- →Work river-bottom and reservoir-edge cover along the North Platte drainage
- →Glass sage-and-juniper breaks at dawn before deer bed in shade
Rocky Mountain Elk
limited opportunitySmall numbers of elk use the higher Seminoe and Ferris Mountains and adjacent timbered country; elk here are localized and pressure-sensitive.
- →Focus on the Ferris and Seminoe high timber and hidden parks
- →Hunt away from roads and reservoirs where elk are displaced by human activity
- →Be prepared to cover ground — elk are scattered and not evenly distributed
Pro tips
- →Download BLM surface-management / land-status layers before you go — the checkerboard here makes on-the-ground legality non-obvious
- →Glass from the sage rises rather than driving through herds; pronghorn eyesight beats you in the open
- →Hit stock tanks and the reservoir shorelines in warm early-season weather
- →Scout the Ferris and Seminoe foothills for the better mule deer bucks
- →Fill your fuel tank in Rawlins — services are sparse once you leave the highway
Watch out for
- !Union Pacific checkerboard and corner-crossing legality along the I-80/railroad corridor
- !Private ranch inholdings interlocked with public land — verify boundaries
- !Clay/gumbo two-tracks impassable when wet
- !Limited cell coverage away from I-80 and U.S. 287
- !Fall fire restrictions on BLM land in dry years
Logistics
Rawlins on I-80 is the practical base with fuel, lodging, and supplies; Seminoe State Park has campgrounds at the reservoir. Cell service drops quickly off the highway corridors — carry paper/BLM land-status maps or an offline mapping app with land ownership. Roads are mostly two-track and gumbo clay that turns impassable when wet.
