Because I was guilted into posting a photo because it's been so long, here we go.
This is from Feb 2021. The name of the rock, fittingly, is Hollow Rock. It's just sound of Grand Portage MN, near the Canadian Border. It was a solid -25F this morning, absolutely frigid. I had all kinds of issues with my battery getting too cold and dying on me (sign, mirrorless cameras...).
There ended up being a couple photographers there this morning all there for the sunrise. Mostly from around Minnesota, but one from the Chicago area who regularly makes his way to the North Shore of Lake Superior and was building a photography community made up of folks from around the Midwest US. The camaraderie of photographers suffering together in the bitter cold really made enduring it completely worth it. (that and the photos we all left with...)
Depending on the day to day temperatures, it is common for ice shards like you see here on the right side of the foreground to form this time of year. Wave action can usually keep the lake open, but some calm, cold nights you see a layer of ice forming up to an inch thick. When the morning breeze blows that freshly frozen water into shore, it fractures into these shards and piles them up against one another. Another example of this ice can be seen
here.
