Pawnee Pioneer Trails Scenic and Historic Byway runs through the ranching and farming country of the South Platte River Valley in northeastern Colorado. This part of the high plains (known as the “Colorado Piedmont”) is much more rugged and varied than the rolling terrain that surrounds it, and its gullies, escarpments, potholes and buttes are home to a surprising abundance of wildlife. Pawnee National Grassland is one of the finest birding destinations in North America, and the geological strata exposed in its landforms contain world-class fossils from several eras. |
