Donaldson/Bronson Cave (also known as Shawnee Cave) is located entirely within Spring Mill State Park. The cave is the downstream section of the Shawnee drainage system (Lower Twin and Upper Twin caves make up the remaining sections). For the entire length of the cave, you are in water.
Ice caves come in two forms. A cave formed entirely of ice is actually called a glacier cave and as the name implies, forms in glaciers. Water runs through or under the glacier and forms a cave. Glacier caves are very dangerous to enter and explore because of shifting and melting ice. They are a little too adventurous for the novice. The other type of ice cave can be any cave type (limestone, lava tube, etc.) that has ice in it year round. These caves trap cold air. Water entering the cave freezes and stays frozen year round.
