Hunt Area 110, Grinnell, Wyoming

Hunt Area 110 boundaries and terrain differ by species under Wyoming's numbering system. The deer Hunt Area 110 (Park County, Cody Region) is part of the Upper Shoshone herd unit in the foothills and drainages east of Yellowstone National Park, bordering Areas 105, 106, 111, and Yellowstone NP; terrain ranges from sagebrush river bottoms along the Shoshone drainage to steep Absaroka Mountain foothills, elevations roughly 5,000–9,000 ft. The antelope Hunt Area 110 (South Greybull River, Park/Hot Springs counties) spans approximately 614 square miles (393,182 acres) with elevations in the range of approximately 6,200–9,600 ft; the western half is mountainous and largely devoid of pronghorn, while the lower eastern valleys provide prime sagebrush-grass habitat. [NOTE: An earlier draft cited a high elevation of 12,908 ft; this figure is unverified and inconsistent with GIS data for this unit — removed.] The elk Hunt Area 110 (Upper Platte River, Albany/Carbon counties, SE Wyoming) is a separate geographic unit covering approximately 456 square miles in the Snowy Range/Medicine Bow Mountains, with elevations of 6,900–10,700 ft, high plains desert at lower elevations transitioning to Medicine Bow-Routt National Forest at higher elevations.

IMPORTANT — Wyoming uses the number '110' for different hunt areas for different species in different geographic locations. Deer Hunt Area 110 is in Park County (Cody Region, Upper Shoshone herd); elk Hunt Area 110 is in Albany/Carbon counties (Snowy Range, SE Wyoming, part of EL533 herd unit); antelope Hunt Area 110 is the South Greybull River unit in Park/Hot Springs counties. These are not the same geographic area. The deer and pronghorn Area 110s are in the same general Cody/Bighorn Basin region; the elk Area 110 is roughly 200 miles southeast. CWD: Deer Hunt Area 110 (Park County) has been CWD-positive since 2016 (confirmed by WGFD Nov. 2025 news release). The area borders other CWD-positive areas (105 detected 2019, 111 detected 2016) and Yellowstone NP. Elk Hunt Area 110 (Snowy Range) is a CWD monitoring area — hunters are encouraged but not required to submit samples. Carcass transport: whole deer, elk, and moose carcasses cannot leave Wyoming; head and spinal column must be removed and disposed of properly when transporting from CWD-positive areas. The Greybull River HMA prohibits mule deer hunting; whitetail doe/fawn hunting is restricted (pivot fields closed per HMA map); 10 permission slips available per week for elk general season (confirmed from WGFD HMA page). Mule deer herds in the Upper Shoshone (deer Area 110) remain below population management objectives as of 2025, attributed to drought and elevated CWD prevalence. 2026 specific season dates are from Chapter 5, 6, and 7 drafts dated 03.16.2026.4 — consult wgfd.wyo.gov/HuntPlanner and final published regulation booklets for authoritative data. Public land percentage of 74.7% (approximately 75%) applies to the antelope Area 110 (South Greybull River) — USFS 46%, BLM 16%, State 13%, Private 24% (HuntScore/WGFD); elk Area 110 is approximately 73% public land; deer Area 110 public land percentage not confirmed from official sources.
