Geology, the Prairie Dog Town Fork, and the Lighthouse
Palo Duro Canyon was carved by the Prairie Dog Town Fork of the Red River into the southern High Plains over approximately one million years. The canyon exposes four distinct geological formations representing about 240 million years of Earth's history, including the red Quartermaster Formation of the late Permian period (responsible for the canyon's signature red coloring), the white Tecovas Formation, and the colorful Trujillo Formation. The result is a layered, colorful canyon system that geologically resembles a smaller, more compact version of the Grand Canyon, though the rock types and time periods exposed are different.
The canyon's most famous landmark is the Lighthouse — a 310-foot freestanding rock pillar near the southern end of the park, the official symbol of Palo Duro and one of the most photographed features in West Texas. The Lighthouse is reached only by foot via the 5.75-mile round-trip Lighthouse Trail, a moderate hike that crosses canyon floor before climbing to the base of the pillar. The trail is the single most popular hike in the park and a near-required experience for visitors with the time and fitness to complete it.
The canyon's ecology spans a remarkable range for a place embedded in the dry Panhandle. The canyon floor supports cottonwoods, juniper, and mesquite woodlands; the slopes host yucca, prickly pear cactus, and grasses; the rim returns to short-grass prairie. Wildlife includes mule deer, wild turkeys, roadrunners, the rare Palo Duro mouse (found nowhere else), and the herd of Texas Longhorns kept at the park as a living link to the canyon's nineteenth-century ranching history.
