General W(H)MA Information:

Spence & Moriarity Wildlife Management Area and Inberg/Roy Wildlife Habitat Management Area are contiguous and located north east of Dubois.  Access to the Human Presence Closure Area will be through the Bear Creek gate located milepost 9.6 on the East Fork Road. 

Each of the twenty-five (25) persons randomly drawn for early access must possess an appropriate permission slip prior to entering the Human Presence Closure Area.

It is the permission slip holder's responsibility to know, understand, and comply with the early access rules in order to access the Human Presence Closure Area. Failure to comply is a violation of Game and Fish Commission Regulations and may result in fines, the termination of access privileges, and/or other legal penalties. Permission slip holders should abide by the early access rules and respect the land for continued access opportunities.

Other Information:
This wildlife habitat management area is in the beautiful Absaroka Mountains.  This is crucial winter range for the Wiggins Fork elk herd and many other species of wildlife.  Besides providing crucial habitat, the area has archaeological sites, good fishing, other recreational activities and a tragic namesake.

Mule deer, pronghorn antelope, moose and bighorn sheep herds also winter here.  If you like to fish, you can try your skills at catching brook trout, brown trout, cutthroat trout and whitefish.  An impressive cottonwood forest and riparian shrubland borders much of the Wiggins Fork River, which runs through the area north to south.  Rough, broken country lies above the river to the east.  Sagebrush grassland and mountain shrublands cover the hills and bench lands.

Relatively mild winters and historic abundance of big game made this area a favorite wintering site for various Indian tribes, the Sheepeater Clan of the Shoshone tribe was the most common.  A trap used by the Sheepeaters to catch bighorn sheep is located on adjacent U.S. Forest Service lands.  A permit is required for collection of any fossil or artifact.  Please help to protect these archaeological treasures.

The area was previously known as the East Fork Wildlife Habitat Management Area, but it is now named for two Wyoming Game & Fish Department employees.  Kirk Inberg, Kevin Roy and pilot Ray Austin were attempting to locate a wounded grizzly bear when their plane went down in a storm on October 16, 1991.

This WHMA lies within bear country, please visit our bear wise page for information on recreating in bear country -

Camping is permitted in designated camping areas with a 14-day camping limit.

The area is closed each year from December 1 through May 15 to prevent interference with wintering wildlife.
