Niobrara County, WY was created in 1911 from the eastern part of Converse County, WY. It was organized in 1913 and
named by Harry S. Snyder after the Niobrara River which rises west of Lusk, Niobrara County seat.
The name "Niobrara" is taken from the Omaha-Ponca Indian name Ni (water) obthatha (spreading) ke (horizontally). It was called "Running Water" by early settlers. The Cheyenne Indian name for the Niobrara was Hisse yovi yoe, which means unexpected or surprise river. They came upon it suddenly on the prairie, as it is marked with few trees.
The Niobrara County seat, is located in Eastern Wyoming in the tall grass country and is served by highways
connecting in all four directions. Only 3,200 people live in rural Niobrara County, averaging out to almost 524
acres per person. As a ranching community, Lusk has a relatively stable economic base. Lusk was named for Frank
Lusk, an early rancher who donated land for the town site. Today, it is a trading center for a ranching and

which Native Americans obtained material for paint. Through this area ran the Cheyenne and Black Hills Stage Line,
