Large numbers of Hereford and other cattle are raised on ranches in Yellowstone Country. Cities, such as Glendive, Miles City, and Billings, have prospered because of the presence of the river. Glendive I-94 is the southern route into Montana and Yellowstone Country. Visitors entering Montana from the east usually stop in Glendive. Makoshika State Park, an area of rugged badlands located east of the city, is a popular attraction.
Tourists often go hunting for Montana moss agates in the nearby Yellowstone River Valley.
The moss agate is a type of quartz gemstone. Amateurs and rockhounds dig through gravel deposits along the river to find the agates. When cut and polished, moss agates make beautiful jewelry. Moss agate jewelry is sold at the Jordan Inn gift shop in downtown Glendive. The Comfort Inn in Glendive offers good lodging.
