HD 350 covers the Yellowstone River corridor and surrounding prairie breaks between Forsyth and Miles City—classic eastern Montana cattle and breaks country, with the Yellowstone winding through and the ponderosa-pine breaks rising on both sides. Elevations run from about 2,400 feet on the Yellowstone bottom to 4,000 feet on the higher prairie ridges. The river bottom is cottonwood gallery forest, willow thickets, irrigated hay, and ag fields—prime whitetail. The breaks immediately above the river are sandstone outcrops, badlands, and timbered ponderosa-and-juniper draws that hold mule deer. Beyond the breaks the country opens into rolling sage prairie, native bunchgrass, and CRP grass. The Tongue River dumps into the Yellowstone at Miles City, the Powder a little further east. Whitetail are dense in the bottoms; mule deer use the timbered breaks and the rocky outcrops; pronghorn work the prairie flats; some elk move through the breaks in late season. BLM and DNRC state trust sections checkerboard the breaks and the surrounding prairie, with significant private ranch ground covering most of the river bottom and the dryland flats. Block Management is essential and the BMAs along the lower Yellowstone fill up. I-94 follows the river; US-12 hits Forsyth; secondary highways and a county road grid handle the rest. Forsyth and Miles City both have gas, groceries, motels; Miles City is the bigger of the two with a hospital and the historic Range Riders Hotel. Cell service holds along I-94 and weakens on the back roads. The breaks roads gumbo up when wet—the rule applies. The lower Yellowstone produces more big mule deer than the magazines admit, especially on BMA tracts where landowners limit pressure.
