Area 45 covers the country around Glenrock and the southern Powder River Basin between Casper and Douglas—rolling sage prairie, eroded breaks along the North Platte and Big Muddy Creek, and the long benches that climb gently up toward the Laramie Range to the south. Elevations run from about 4,500 feet on the river bottoms to 6,500 feet on the higher benches. The North Platte cuts through with cottonwood-and-willow bottoms and irrigated hay meadows; the surrounding country is sage prairie with scattered ponderosa pine on the breaks where coal-bearing formations have eroded. The region's coal-bed methane and oil and gas activity is everywhere—pumpjacks, gas plants, gravel pads, and the network of lease roads that come with extraction. The wildlife adapts; the country is still good country. BLM, state trust, and significant private with extensive HMA and Walk-In access. I-25 frames the south; US-20/26 cuts east-west; county and lease roads thread the basin. Glenrock has gas and a grocery store; Casper is the full-service hub 25 miles west. Cell service is fair on I-25 and reasonable through the developed gas fields. Antelope rifle in October is the headline—the open sage holds strong pronghorn numbers and the broken creek-side country is where the mature bucks live. Mule deer use the breaks and pine-edge country; whitetail are in the river bottoms. Wind is constant, energy traffic is constant, and the country is bigger than it looks driving I-25.
