About This Home
This expansive and contiguous shortgrass prairie ranch offers low overhead and the capacity to support over 1,000 cattle year-round. An exceptional property, featuring a convenient location, productive land, and breathtaking scenery, along with robust infrastructure, working facilities, and reliable water sources. The Wild Horse Basin Ranch is enhanced by its state and BLM leases, as well as a unique long-term lease with PacifiCorp and several other private leases on the property. Spanning nearly 93,000 acres, this offering is incredibly rare, especially just 25 miles from the growing city of Casper. Centrally located between the Granite Mountains to the north and the Bighorn Mountains to the south, this ranch has a storied history of cattle ranching.
