Yes, there are caves in the Arctic. Some notable examples include:

1. Tartu Cave: Located on the Canadian Arctic Archipelago's Ellesmere Island, Tartu Cave is the world's longest gypsum cave. It stretches over 100 kilometers and contains impressive gypsum formations.

2. Nenio Cave: Also situated on Ellesmere Island, Nenio Cave is known for its diverse ice formations. It was formed by meltwater streams and boasts spectacular ice stalactites, stalagmites, and pillars.

3. Nipisat Cave System: Located in northwestern Greenland, the Nipisat Cave System is a network of caves formed by glacial meltwater. It is known for its extensive labyrinthine passages and underground waterfalls.
