"Icy Sea Stack at Tettegouche State Park"<br />
<br />
Spray from Lake Superior's big waves on subzero days freeze on everything they touch, creating fantastic ice sculptures. It's amazing that the trees atop the sea stack and along the shore can endure the harsh conditions. This sea stack used to be connected to the mainland with the iconic stone arch until the arch crumbled into the lake in 2010. Tettegouche State Park, Minnesota, Lake Superior.
