The area around Palo Pinto Mountains State Park, with its rugged terrain and scenic views, was part of the North Texas frontier patrolled by Buffalo Soldiers in the late 19th century. Units like the 9th and 10th Cavalry from Fort Richardson and Fort Griffin were responsible for securing this region, protecting settlers, and maintaining order against various threats. While the park is still under development, its future visitors can envision the troopers who once traversed these hills, contributing to the eventual settlement and safety of the area.
