HD 670 covers the country in the Custer Gallatin Sioux Ranger District around the Beaver Creek and Boxelder Creek drainages in Carter County—isolated ponderosa-pine ridges, sandstone outcrops, sage parks, and creek-bottom corridors in the country between Ekalaka and the South Dakota border. Elevations run from about 3,000 feet on the surrounding prairie to 4,500 feet on the higher pine-covered ridges. The country is the same striking SE MT pine-island landscape as the Long Pines and Chalk Buttes country: scattered ponderosa pine ridges rising abruptly out of sage prairie, with juniper-and-mountain mahogany draws, badlands-style sandstone outcrops, big sage parks, and cottonwood-and-willow corridors along the seasonal creek drainages. The pine ridges hold a real elk population in country no one would expect to support elk; mule deer use the timber-sage interface; whitetail in the bottoms; pronghorn on the prairie; turkeys (Merriam's) in the pines. Custer Gallatin NF (Sioux Ranger District) covers the principal public timber tracts, with BLM scattered through and the bulk of the surrounding country private ranchland. Block Management is essential. Limited road access—the county and forest dirt road grid handles everything, gumbo when wet. Ekalaka is the supply outpost with gas, basics, the Carter County Museum (worth a stop). Baker is north, Belle Fourche SD southeast. Cell service is essentially gone. Roads turn lethal when wet. The Sioux District country is a real public-ground sleeper for hunters who can plan around weather and put in the boot leather.
