The Grey Cloud Dunes Scientific and Natural Area was acquired by the Minnesota Department of Natural Resource in 1998.
Grey Cloud Dunes Scientific and Natural Area is a rare prairie with dunes rising in waves cresting 10 to 20 feet.
Distinct plant communities are present throughout the area, including little bluestem, penstemon, prairie dropseed, sand reed grass, gramma grass, and silky prairie clover plants. Tree species consist of elm, silver maple, cottonwood, and box elder. Blue racers, an uncommon Minnesota snake, and prairie skinks are also present.
