Big Stone National Wildlife Refuge: Nature Rocks!
U.S. Fish and Wildlife Service - Midwest Region


Sept. 25, 2010, Big Stone National Wildlife Refuge hosted a Nature Rocks Day (Public Lands Day) event for families and youth naturalists.

Activities featured a visiting geologist from the University of Minnesota-Morris who taught visitors about the granite outcrops found on the Refuge and in the Minnesota River Valley. The Refuge biologist also talked about the plants found in association with the outcrops.

Other interactive activities for kids and families included scavenger hunts, 'rock' trivia and trail walks. Big Stone NWR is one of 14 FWS locations in the country hosting an event.

Nature Rocks is a program developed by the Children & Nature Network and ecoAmerica to inspire and empower families to play and explore in nature for healthier, happier and smarter children. The website and all related materials are updated frequently to provide families with the most current tools and information to connect with nature, including nature and event finders, community tools, over 100 activity ideas, and seasonal activity guides. Current partners are The Nature Conservancy, REI, the American Heart Association, the American Camp Association and The U.S. Fish and Wildlife Service.

I came across this video while cleaning out my hard drive. It was recorded in Aug 2010. Every time I go back home, I make it a point to drive through the Big Stone Wildlife Refuge that is located in Minnesota between Ortonville and Odessa (at the bottom of the bump on western side of the state). The auto tour is about 6 miles long. It may be nothing special to some people, but it is to me for at least 3 reasons. I have edited a little to keep it under 10 min. Soundtrack is provided by Eric Lindell which I happened to be listening to at the time. If you don't like it, it doesn't matter ~ because the driver gets to choose :)
