Fleeting beauty: Apostle Islands Ice Caves opened for one spectacular day

More rare than Yosemite’s annual Firefall, less predictable than the synchronized fireflies of Great Smoky Mountains National Park, the Ice Caves of the Apostle Islands are a truly ephemeral phenomena. Temperatures must plummet and stay down for weeks to freeze this corner of Lake Superior tight as a drum. Winds must be light to keep that ice from cracking and lay it down thick enough for people to walk more than two miles each way over deep, space-black water. In Alaska’s Katmia National Park, the brown bears return for the salmon run like clockwork every year. In the Apostle Islands National Lakeshore, the right conditions for the words “the Ice Caves are open” have not happened since 2015. They did this year.

For a day.

The word spread like lightning, flashing at the speed of social media and by the time I got to the shuttle bus pick up location on Monday morning, the line had already formed hundreds deep. The Ice Caves were open and the whole world, it seems, was going. They would be closed the next day because of an approaching storm but no one knew that at the time. They only knew “the Ice Caves are open.”

By mid-morning, there were some 1,250 people registered on the National Park Service system (that number would surpass 2,500 by afternoon). They came in blue jeans and carrying babies in backpacks, breaking out winter gear they hadn’t worn in years. They came from Washington D.C. and Chicago and Minneapolis. And they came in a hurry. One woman I spoke with got pulled over for speeding on her way up from Madison, but the officer let her off when she told him “I need to get to the Ice Caves before they close!”

It was a mass migration of human beings seeking a rare connection with beauty, with magic, with the power of nature. It wasn’t on a IMAX screen. It wasn’t Artificial Intelligence or a simulation. It was wet socks and sore legs and real effort. All to see the frozen fireworks of ice cascading off solid rock. They came here for the beauty.

To stand inside a sandstone cave carved by the almost unfathomable power of waves and time and bring your face inches away from the intricate beauty of a piece of ice so fragile it seems even the warmth of your breath will send it toppling, is to understand the fleeting nature of beauty, maybe even of life.

It all passes – beauty, art, these words might as well be written in ice. That is not even in question. What is in question, perhaps, is will we take the time to see it before it does, to let it sink into our souls before it is gone? Because if the artistry of ice that is the Apostle Islands Ice Caves teach us anything, it is that it is all fleeting. It will all disappear. The best we can do is to be there before it does and stand there in awe while we can.

Due to an approaching storm the national park service closed the ice caves on February 17th, until further notice. Strong wind and waves from an incoming storm wiped out the ice in front of the mainland caves overnight on February 17 and 18th. Always check the NPS website for current closures and safety conditions.
