HD 403 covers the rolling prairie and creek-break country south and east of Miles City—classic eastern Montana cattle and dryland-wheat ranching country with timbered creek drainages cutting through. Elevations run from about 2,400 feet on the Yellowstone and Tongue River bottoms up to 4,000 feet on the higher prairie ridges and the Pumpkin Creek divide. The country is mostly open: native bunchgrass and sage on the rolling prairie, dryland wheat and CRP on the cropland, ponderosa-pine and juniper stringers in the deeper coulees, and cottonwood-and-willow corridors along Pumpkin Creek, the Tongue River, and the smaller seasonal drainages. The lower Tongue River breaks make for some genuinely scenic country with badland-style outcrops. Mule deer use the timbered creek breaks; whitetail concentrate in the Tongue and creek bottoms; pronghorn work the open prairie and CRP; some elk filter through the breaks. BLM and DNRC state sections checkerboard through the prairie, with the bulk of the land private ranches—old SE MT cattle outfits. Block Management is essential and the BMAs around Miles City have generally good participation. I-94 cuts the unit east-west, US-212 hits the south part, MT-59 and the county road grid handle the rest. Miles City has full services—gas, motels, the historic Olive Hotel, the Bucking Horse Sale grounds, a hospital. Cell service holds along the highways and weakens off them. Section roads gumbo when wet; give them time. The whitetail rut along the Tongue and the late-season pronghorn opportunities on Block Management ground are the headline opportunities.
