The Wyoming Game and Fish Department reminds antler hunters that gathering horns or shed antlers is prohibited from January 1 through April 30 on public lands west of the Continental Divide in Wyoming. This regulation has been in effect since 2009. Many big game winter ranges in both Teton and Sublette counties have further restrictions to either human presence or motor vehicles during the winter months. However, the shed antler regulation does apply to all other federal or public lands not covered under such winter range closures. Similarly, Wildlife Habitat Management Areas (WHMAs) managed by the Wyoming Game and Fish Department in the Jackson and Pinedale Regions are closed to human presence December 1 through April 30. That includes the area from Snow King south, south of the town of Jackson and the South Park feed grounds.
