	Overview
	Designated on August 22, 2016, River Warren Outcrops SNA is one of Minnesota’s two newest SNAs. Its 89 acres include a prairie restoration, densely wooded bedrock outcrop, and floodplain forest along the east bank of the Minnesota River. Plains prickly pear and Kentucky coffee tree, two species of special concern in Minnesota, are found here. Future management plans include the removal of buckthorn and redcedar from about 85% of the site, and continued restoration of a former agricultural field to prairie. An unusual feature of this SNA is 1.6 miles of horse trails. These trails were on the site when the land was purchased by the DNR, and they will continue to be maintained by the seller.

	History
	This SNA was designated August 22, 2016.

	About Jun 11, 2020 Talk about some ancient history! The Morton Gneiss rock outcrops at this site are some of the oldest bedrock in the world (over 3 billion years old). The glacial River Warren, an outlet of Glacial Lake Agassiz, exposed this bedrock on the surface, (about 9 thousand years ago). Though you may not visit this SNA in person, it is rewarding to know that we, as Minnesotans, have together protected this important habitat for the rare and wild in Minnesota. mndnr.gov/snas/sna00001
