The park current has 2 wolf packs. Depending on your take on things this is either very coo or not so much. If you have never heard wolves howl at night, it is really amazing.
The park is also far enough north that there are black bears. This means don't be dumb in camp. If a bear gets food from you, you are indirectly signing its death warrant. If you are in a back country campsite, secure your food. And no matter how cute, don't hold the cubs...
I am pretty open with the belief that at least until recently, Minnesota has done conservation better than most states. We have a great history of giving selflessly, for the betterment of our neighbors. Jay Cooke State Park is a perfect example of this. The park was formed on land donated by a power company ad later expanded via other gifts. I'm sure money could have been made by divvying up vacation home lots, but because the gifts were made, Minnesota has a great state park.
