The Crystal Lake Caves in Dubuque are one of Iowa’s most unique and beautiful natural attractions. The Crystal Lake geology was formed over millions of years as slow-moving groundwater carved the cave out of layers of limestone. As the water became acidic, it seeped through the ground and created the walkways that visitors can now walk to get a closer look at the unique sights within the caves.
Crystal Lake Cave was discovered in 1868 by a lead ore miner named James Rice.

Rice sank a 40-foot shaft into the limestone and discovered several hundred feet of natural passage which led to this large system of caves.

The intricate formations covering the walls and ceilings were formed due to minerals dripping from above the caverns.
