Area 37 covers the country around Lusk and along the upper Niobrara River drainage—rolling prairie, the Niobrara River bottoms, and scattered breaks and ridges that pop up out of the grass. Elevations run from about 4,000 to 5,500 feet. The Niobrara is a thin ribbon of cottonwood and willow cutting east through this country toward the Nebraska sandhills, and it carries water and game movement through what would otherwise be dry, open grassland. Sage prairie and bunchgrass dominate the uplands, with eroded breaks of white clay and red sandstone breaking up the horizon and providing the sort of cover deer and antelope use to stay out of sight from the road. Almost entirely private ranch with thin scatters of BLM and state trust. The Walk-In and HMA programs are the difference between a productive hunt and a frustrating drive—the regs booklet matters and so does calling ranches in advance for season-of-permission. US-20 and US-85 frame the country; county roads thread the rest. Lusk is the supply town and Manville is barely there—gas pump, post office, and not much else. Cell service is fair on the highways. Antelope rifle in October is the headline; the open prairie holds quality pronghorn and the mature bucks live in the broken creek-side country. Mule deer use the breaks. Whitetail concentrate hard along the Niobrara cottonwoods. Wind is the constant, and so is the empty horizon.
