Caprock Canyons State Park and Trailway is a big deal in Texas for many reasons. Mostly, it's known for having a special breed of bison. At one time, bison roamed the North American plains in vast herds. An estimated count was 30 to 60 million. But in the mid- to late- 1800s, hide hunters arrived, and what became known as "the great slaughter" reduced the number to less than 1000. Towards the end of the slaughter, individuals showed interest in increasing the herd population by forming their own herds. Leaders in the project were Mary Ann and Charles Goodnight. Today, the descendants of those bison constitute the Texas State Bison Herd. Over time, the herds were donated to Texas State Parks and Wildlife and in 1997 they were moved to Caprock Canyons. The park's population of bison is around 85, and the North American population is said to be half a million.

Another important feature of Caprock Canyons is its trailway - a hiking, biking and equestrian rail trail that meanders through the park and through three Texas counties. It was established in 1993 and covers some 64 miles of trail.

Caprocks Canyon is located about 100 miles southeast of Amarillo, in the Texas Panhandle.
