Dagmar is near the North Dakota line and the Canadian border. It is the trade center for a community of Danish-Americans who have for a long time successfully conducted various cooperative enterprises. The original name of the town, Dronning Dagmar's Minde, was chosen by E. F. Madsen to honor Queen Dagmar of Denmark. Madsen was appointed postmaster when the office opened in 1907 under the shortened name of Dagmar. (from Cheney's
Names on the Face of Montana, Mountain Press Publishing Company) Dagmar is near
Brush Lake State Park. Brush Lake is a deep, clear lake with white, sandy beaches surrounded by grass fields and linear stands of spring wheat. The site offers public access for swimming on the northern portion of the 280-acre lake. The
Medicine Lake National Wildlife Refuge is also nearby. Thousands of migrating waterfowl make their summer home at Medicine Lake National Wildlife Refuge. Great blue herons, white pelicans, sandhill cranes, grebes and 12 different species of ducks share the prairie lake ecosystem. Self-guided hiking and an 14-mile driving tour around the wildlife refuge are some popular options. One tour stop is the site of teepee rings of stone, perhaps 4,000 years old, which mark areas where Indian lodges were built. Another highlight of the refuge is a 100-foot observation tower which offers a panoramic view of the area, and an observation platform with telescopes that provide a view if the largest white pelican colony in Montana, over 10,000 birds.
