Buffalo Soldiers, especially the 10th Cavalry, crossed this sea of sand in the vast, dry West Texas territory in the late 1800s. While battles didn't happen on the dunes themselves, soldiers traveling between forts like Concho, Stockton, and Davis would have faced this unique, water-scarce environment while guarding major routes like the Butterfield Overland Mail. When you explore Monahans Sandhills State Park today (maybe even try sand-surfing!), think of the incredible endurance and skills needed to navigate the dunes.
