About this property

Split Rock, also known as Twin Peaks, is a mountain in the Granite Mountains of central Wyoming. The peak has an elevation of 7,305 feet (2,227 m), and is located about 10 miles (16 km) north of the Muddy Gap junction between Casper and Rawlins. The mountain is distinctive for a deep V-shaped cleft dividing its summit. The mountain was a prominent landmark on the Oregon Trail and other early settlement routes in the region, which crossed a low rise at the eastern end of the range between Casper and the North Platte River valley and the Sweetwater River. The mountain summit was listed on the National Register of Historic Places in 1976 for its historic significance.
