HD 339 covers the Moccasin Mountains and the surrounding prairie north of Lewistown—a pair of small island ranges (the North and South Moccasins) rising out of the rolling Judith Basin grassland. Elevations run from about 4,000 feet on the surrounding prairie to roughly 6,400 feet on Big Snowies-feel summits like Big Beaver Mountain in the South Moccasins. The ranges themselves are limestone-and-dolomite cored with rolling Douglas fir and ponderosa pine forest, big grassy parks, and aspen draws on the creek-cut sides. The surrounding prairie is dryland wheat, CRP, native bunchgrass with sage, and creek-bottom cottonwood corridors. Mule deer use the timbered foothills and the limestone reef country at mid-elevation; pronghorn work the open dryland; whitetail concentrate in the creek bottoms; some elk filter down off the higher Big Snowys to the south. A mosaic of BLM, DNRC state sections, and private ranch ground—the BLM tracts in the North Moccasins are real and walkable, but a fair share of the South Moccasins is private. US-191 climbs north out of Lewistown along the east edge; county roads grid the prairie around. Lewistown has full services and is 20 minutes south. Cell service holds along US-191 and gets thin on the back roads. Many of the prairie roads turn to gumbo when wet—give it a day to dry. Block Management is helpful for the private ranch ground; the public timber on the Moccasins is yours to walk. This is a quiet, low-pressure unit that gets overshadowed by the Big Snowys and the Bear Paws to the north, which means a hunter willing to work the BLM tracts can find country to themselves.
