The coordinates take you to the historical Marker on the historical XIT Ranch General Office building where you can get the info for the final location and walk/roll over to the cache. Stealth could be required,
Please be stealthy. Stealth: a cautious, unobtrusive, and secretive way of moving or proceeding intended to avoid detection. This area can be busy at times.
The XIT Ranch was a cattle ranch in the Texas Panhandle which operated from 1885 to 1912. Comprising over 3,000,000 acres (12,000 km2) of land, it ran for 200 miles (300 km) along the border with New Mexico, varying in width from 20 to 30 miles (30 to 50 km). The massive ranch stretched through ten counties in Texas and at its peak regularly handled 150,000 head of cattle. The brand "XIT" was chosen for its difficulty to alter thus thwarting rustlers.

No one from the pages of Indian history carries more clout or mystique than the name of Quanah Parker, last chief of the Comanches. In war, his equal was never seen, but when the inevitable “taming of the west” ensued in the late 1870s, he transferred that war chief ability into a positive force that would shape his Comanche people and the entire future of Indian law and religion.

The Comanche Indians once dominated vast areas of North America—and yet, forced onto reservations, they left little record of their own story. Today a network of 22-foot-tall steel arrows by artist Charles A. Smith marks sites where the Comanches, and their last chief, Quanah Parker, hunted, traded, lived, traveled, and fought. Retrace the footsteps and hoofbeats of the “Lords of the Plains” as you honor their rich culture and history, and learn about a past that is written on the land.
What started out as a group of enthusiastic regional citizens interested in telling the fascinating story of Cynthia Ann and Quanah Parker turned into a public art and commemorative project to mark the sites of Native history in the former Comancheria. Since 2011, the Texas Plains Trail Region's Quanah Parker Trail Steering Committee has facilitated the research about these sites, and overseen installation of more than 70 arrows marking the nearly forgotten-to-public-memory history of the Native American Comanche presence in the Texas Panhandle, predating the arrival of Anglo ranchers and settlers.
