First two photos are of High Falls, a 120 foot falls, on the Pigeon River in Minnesota. The river is the border between the US and Canada. Left side of Falls is US and the right side Canada.
Third photo is also in Minnesota, and is the Falls on I believe on the Beaver River, but it's at Beaver Bay, MN. These and a lot of other falls can be found in the North Shore area of Minnesota.
Uuugh, your last shot is severely over exosed.
