While exploring Tettegouche State Park on New Year’s weekend we hiked up to High Falls and became amazed at the many different ice formations surrounding this water fall. Just looking at this amazing water fall almost completely frozen is beautiful especially set in the winter wonderland of Northern Minnesota however closer examination of the different pieces that make up this scene makes it even more incredible.
There are different shapes, colors, and sizes of the many different icicles near the falls. It’s interesting to imagine how these were formed such as in the photo above. Water flowing over the falls has a darker color so how were these created clear at first and then coated in snow or frost? Guessing at the answer I would say these were formed during a recent rain event which was followed colder temperatures and then the spray from the water fall coated them.
This next picture has multiple colors of ice with a chimney allowing light from the sky to illuminate this natural sculpture. The darker ice which is tinted must have been created from water flowing over the falls but it could also be from water seeping through rocks picking up tannins and minerals causing the water to be tinted and freezing with dripping water from the recent rainfall. What was really interesting to me was the chimney. How was this created? Was there ice there originally that fell creating a hole or was the natural opening wide enough that it never had water running through it?
While exploring further there were these icicles made from water freezing making two different icicles that merged together leaving open space between them for a portion. Also I found the pieces of horizontal ice attached to the vertical icicles quite interesting.
This next picture is showing a zoomed out version of the vertical and horizontal icicles highlighting the horizontal ice. How do icicles get created horizontally? My best guess is going back in time to imagine these being formed over hours, days, and weeks. Initially the clear icicles were made from rainfall freezing. Next mist from the running water fall was strongly blowing towards these frozen icicles freezing almost on contact. So these could be made as a result of heavy rains mixed with strong winds after the rainfall but before the falls froze creating unique ice formations.
This is one of my favorite perspectives looking up at numerous icicles appearing as they are going to fall right on top of you. On the day of this photo these were very secure so no concerns which was confirmed as we broke off one and it did not separate from the rock above easily. In this last picture below I found several different ice formations appearing as a stairway up the falls. Even though it looks like stairs I would never climb it without proper equipment knowing this is a water fall and water is still running underneath this ice making it more unpredictable.
