If anyone is from minnesota and don't mind a little bit of a drive there is an old mining quarry filled with water up in Nashwauk. Go into town coming from Hibbing on highway 37...take a right at the dairy queen and then take a left on Pearson street. Go to the end and park in the alley. Follow the road with the gates across it until you see a part of a fence knocked down on the right side. Follow the trail down to the water. there are 3 jumps from about 30-50 feet and a few spots that are extremely high (over 110 feet) but you must walk about 45 minutes to get to them.
