Big Ice Cave is a single chamber of the ice cellar type, an entrance whcih goes steep down into a huge chamber. This morphology results in a cold trap, as cold air is heavier than warm air. In winter the cold air "flows" into the cave, in summer it stays there. This works similar to refridgerators in the supermarket, which keep their content frozen although they have no lids. This simple physical effect is the reason why this cave contains ice and icicles year round. And obviously it is the reason for its name.
The cave is not a show cave, although you could say it is developed. A short walk down an improved plank trail into the entrance portal and on a wooden platform inside the cave where visitors can see the always present ice floor of the cave. There are no guided tours, no speleothems and not much to say about the cave. Take a sweatshirt or jacket, it may be cold inside.
