    Oregon Caves

    National Monument Oregon

Discover the Marble Halls of Oregon

Nestled deep inside the Siskiyou Mountains, the caves formed as rainwater from the ancient forest above dissolved the surrounding marble and created one of the world's few marble caves. The highly complex geology found on the Monument contributes to the unusual and rare plants and animals found nowhere else but here. Experience the extensively decorated and adventurous "Marble Halls of Oregon."

Did You Know?

This snail was named after an employee of Oregon Cave, not because he was slow but because he wrote the technical description of the snail.

There is a snail that lives on the marble rock outcrops of Oregon Caves that has adapted to use the calcium from the rock to make its shell.
