Jordan and the surrounding expanse of range land is still very much cowboy country and the place retains an Old West flavor. The terrain between Jordan and Circle is famous among paleontologists for its fantastic fossil beds. Dinosaurs and prehistoric creatures once roamed here. In 1904, Tyrannosaurus Rex was discovered near Jordan in the Hell Creek Formation. Visitors can glimpse area history and fossil exhibits at the Garfield County Museum. The population is 354 and lies an hour north of Miles City, MT and an hour south of Hell Creek Recreation Area on Fort Peck Reservoir.
