BLM Pinedale Closes Big Game Winter Ranges

The Bureau of Land Management (BLM) Pinedale Field Office (PFO) is notifying the public that BLM-administered big game winter ranges will be closed to all motorized vehicle travel (e.g., snowmobiles, all-terrain vehicles, pickups, sport utility vehicles) from Jan. 1 through Apr. 30.

Use of these areas by non-motorized means (e.g., walking, horseback, cross-country skiing, mountain biking) is still allowed. Highways, county, and oil and gas roads are not affected unless posted otherwise. Motorized vehicle use on public land the remainder of the year is limited to existing roads and two-track trails.

This annual closure has been in effect since 2008 and is necessary to protect elk, moose, pronghorn and mule deer from disruptive human activities which, during the difficult winter months, can increase the mortality rate for these animals.

The following BLM-administered lands are included in this closure:

  • The Ryegrass, Bench Corral, Deer Hills, Calpet and Miller Mountain winter ranges including lands north of Fontenelle Creek, east of the U.S. Forest Service Boundary, west of Highway 189 and south of Horse Creek.
  • The Mesa winter range including lands east of County Road 110 (East Green River Road), north of County Road 136 (Paradise Valley Road), west of the New Fork River and south of State Highway 191.

Exceptions to this closure include:

  • The Wyoming Game and Fish Department (WGFD), the Department of Agriculture Animal Plant Health Inspection Service (APHIS), Sublette County Sheriff’s Office and the BLM when performing official duties;
  • Operators of existing oil and gas facilities performing maintenance and pumping, as approved in their permits;
  • Livestock operators conducting permitted activities;
  • Utility companies conducting emergency maintenance after notifying the PFO; and
  • Other users who have been granted an exception by submitting a written application to the PFO for review and approval.

Signs will be posted at key locations going into the closed areas. A map is available at

For more information, please contact Rusty Kaiser at 307-367-5317 or visit the PFO at 1625 W. Pine St., Pinedale, Wyo.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
