The diamond hole is located in Kentucky, the most attractive part of which is the calcite hanging structure. Because its appearance is similar to Bacon, people vividly call them "cave Bacon". The diamond cave was discovered in 1859. It was formed by the continuous deposition of layered flowstones by water-borne minerals along a repeated route.
Changes in surface rainfall, mineral content balance, and other hydrological and cave phenomena can all affect the water movement speed and mineral content above the flowstone, eventually creating a layered structure reminiscent of bacon. These calcites like bacon give people a sense of appetite, when enjoying the beautiful landscape, you will feel your stomach cooing. Thousands of stalactites, stalagmites, and flowing stones dazzle people. Due to the effect of lighting, the cave is more dazzling.
