State Park: Birding, Hike, History, Picnic, Walk, Water Sports
One of Nebraska’s most intriguing and unusual park areas. Relics of bygone ages mingle with more recent yesterdays to present a kaleidoscope of time found in few places in the High Plains. Here have been found the bones of prehistoric rhinoceros, mammoths, and mastodons, all ancient mammals that once roamed the Great Plains.
