state park in Rock County, Minnesota, United States
Blue Mounds State Park, in southwestern Minnesota, consists of more than 2,000 acres (810 hectares), mostly tallgrass prairie, but also including a small man-made lake and some woods.
The most exceptional characteristic of this park is the mound for which it is named.
Blue Mound is not a mound; it's a cliff, and a manifestation of the Coteau des Prairies, an enormous plateau in the Northern Plains of the United States. The Coteau has maximum dimensions of approximately 200 miles by 100 miles, and extends from eastern South Dakota through the southwest corner of Minnesota, and into northern Iowa. Locally the Coteau is known as Buffalo Ridge.
Blue Mound isn't actually blue, either, although it does appear to be when viewed from a distance on a dusty or hazy day. The rock is actually a pink or reddish hue.
The park is home to about 40 species of mammals and no fewer than 200 varieties of birds. The park's 2000 acres represent the largest segment of preserved tallgrass prairie in the Minnesota State Parks system. Common varieties of tall prairie grass that occur in Blue Mounds include Big Bluestem, Indian Grass, Sawgrass, Prairie Smoke, and others. In addition, prickly pear cactus thrive in the park's dry and rocky soil. The cactus typically bloom in June and July. Wildflowers bloom all spring and summer. The Western Fringed Orchid is believed to be present here as well, but due to its rarity and fragility, its location is a well-kept secret.
Temperature extremes in excess of 105 °F (41 °C) may be observed in July and August, and temperatures of −25 °F (−32 °C) or colder may occur in January and February. Annual precipitation runs just short of 30 in (760 mm) on average.
Blue Mounds State Park is three miles north of Luverne on US Highway 75.
The park has 73 drive-in campsites, of which at least 40 have electrical hookups. Showers and toilets are available on site as well.
