Minnesota DNR

The Nature Conservancy


This small prairie has never been cultivated. It is a mosaic of mesic prairie and wet prairie with small pockets of cattail marsh. In August of 2011, a drought year, both the wet prairie and the cattail marsh were dry.

The Minnesota DNR Web page for this site recommends parking on the south shoulder of 300th Street SW at the northeast corner of the site. However, the road is narrow, the shoulder nonexistent, and the drop-off steep. The only parking spot for this SNA is the field approach on the south side of 300th Street SW near the northwest corner of the site. However, it is deeply rutted. Once on, a vehicle without four-wheel drive may have difficulty backing off.





Four-wheel drive recommended
