Before Great Basin was designated as a national park, there was Lehman Caves National Monument, which is now part of Great Basin National Park.
Absalom Lehman, who discovered the limestone cave with its intriguing formations, conducted private tours for hundreds of visitors in the 1880s. You can still tour the caves today. Location: Lehman Caves may be accessed on the northeastern side of Great Basin National Park. Lehman Caves may only be entered with a guided tour.
