Located in Minnesota, the waterfalls freeze at Minneopa in the pattern in which they fall. While it is always dangerous to get up close and personal to a frozen waterfall, this is a great place to do so. Note that there is always a risk of falling ice chunks, as the majority of the ice is just hanging off the top of the river bed above. Always be careful and never venture onto frozen ice if there is any doubt of safety or its thickness. Make sure to explore the limestone rock surrounding the falls and read the names and messages carved in there.
