Pawnee National Grassland is located in Ault, CO. Even though the Pawnee Buttes are the main attraction at the grassland, there are numerous other opportunities for nature photography. For instance, several species of wildlife are found here. Cattle, broad-tailed hummingbirds, and pronghorn are just a few animals that call this grassland home. In addition to animals, dozens of types of wildflowers and plants are found at Pawnee National Grassland throughout the year.
