Dawson County

Dawson County is an administrative division in eastern Montana covering about 2,383 square miles with varied terrain. Rolling hills, river valleys, and prairie grasslands make up the landscape across the region.

The county was established in 1865 and named after Colonel William C. Dawson, a rancher and politician of the 1800s. His influence shaped the early settlement and development of the area.

The Glendive Historical Society displays artifacts that reflect how farming and industry shaped the community over generations. These collections reveal the daily lives of the people who built this region.

Administrative services are handled at the Glendive Administrative Center, located centrally within the county. Visitors can find general information and get oriented to the region there.

One of the largest Triceratops skulls ever found was discovered in the Hell Creek Formation here, dating back over 65 million years. This fossil discovery makes the county a significant location for paleontology.
