Post Park

The reason there is anything here at all is the water. In a region where reliable springs are rare, this one, at the foot of a bluff the early Spanish speakers called Pena Colorada, meaning red rock, was valuable enough that the U.S. Army built a post beside it. Troops arrived in 1879 and 1880, and the camp, first called Cantonment Pena Colorado and later Camp Pena Colorado, guarded the region during the last years of conflict on the Texas frontier.

Among the soldiers stationed here were troops of the 10th Cavalry, the Black regiment widely known as the buffalo soldiers, who served across the West Texas frontier in this era. The camp was never a grand fort, more a working outpost at a dependable spring, and the army abandoned it in 1893 once the frontier had quieted. A historical marker at the park tells the story on the very ground where the post once stood.

What the soldiers valued for survival, travelers now value for its beauty. The spring still feeds a small pond, and the old cottonwoods have grown tall and broad, throwing deep shade over a lawn set with picnic tables and grills. On a hot West Texas afternoon, the difference between the sunbaked plain and the cool green under these trees is striking, and it is easy to see why the park has been a local gathering place for generations.

Because water and trees are scarce out here, the park is a magnet for wildlife, and it is especially loved by birdwatchers. Songbirds, waterbirds, and migrants passing through the region all funnel into this green pocket, so a patient hour with binoculars near the pond can turn up birds you would never spot on the open grassland. Anglers drop a line in the pond, families spread out on the lawn, and quiet visitors simply sit and enjoy the rare sound of water in the desert.

Post Park lies about five miles south of Marathon by local road. The way in is straightforward but rural, so drive slowly on the final stretch and watch for livestock, cattle guards, and rough patches. It is a simple day-use park with basic facilities and no services, so bring your own water, food, shade if you want extra, and anything else you might need for a picnic or a morning of birding.

The best times to come are early morning and the hour before sunset, when the birds are active and the desert heat lets up. Give yourself an unhurried visit: walk the pond, read the historical marker, listen for birds in the cottonwoods, and let the shade do its work. Then it is only a short drive back into Marathon for a meal and a room. For a free stop so close to town, Post Park delivers a lot, history, wildlife, and a green oasis all at once.
