These caves provide an opportunity for experienced cavers to delve deeper into Missouri’s underground world. However, it is essential to note that many wild caves used by bats in the state park system are temporarily closed to help prevent the spread of a fungus that harms bats, but does not affect humans.
Missouri: The Cave State
Karst Landscape and Geology
Missouri is known as “the Cave State” because it is home to over 7,000 recorded caves, making it a significant location for cave enthusiasts and researchers alike. The prevalence of caves in Missouri is due to its karst landscape, which is characterized by porous limestone and dolomite formations. This geology creates features like caves, springs, sinkholes, and natural bridges, providing unique habitats for a variety of plant and animal species.
Many of Missouri’s caves are found in the Ozarks region, particularly in Shannon County, which holds the title for the most caves in a single county with over 730 recorded examples. These caves can range in length from 20 feet to more than 30 miles of mapped passages.
Types of Caves: Show Caves vs Wild Caves
There are two main categories of caves in Missouri: show caves and wild caves. Show caves are open to the public for guided tours, providing visitors the opportunity to experience the state’s underground beauty firsthand. Currently, there are 20 show caves in Missouri, including popular attractions like Onondaga Cave and Cathedral Cave at Onondaga Cave State Park, Fisher Cave at Meramec State Park, and Ozark Caverns at Lake of the Ozarks State Park.
Alternatively, wild caves are not open to the public and remain largely undisturbed by human activity. Wild caves in Missouri are often inhabited by bats. In order to protect these animals from the spread of a fungus that harms bats but does not affect humans, many wild caves have been temporarily closed to the public.
Conservation and Research
Missouri’s caves are not only geological treasures but also essential habitats for various plants and animals, including threatened and endangered species. As a result, conservation efforts are crucial to ensure the continued protection and preservation of these unique underground ecosystems.
Organizations like the Missouri Department of Conservation and the Missouri Department of Natural Resources are responsible for managing and protecting the state’s cave resources. Alongside these management efforts, scientific research is conducted to expand our understanding of cave-dwelling species, such as bats, and the geological processes that have shaped the Missouri landscape.

Cave Formations and Unique Features
Missouri is home to over 7,000 caves, earning it the nickname “the Cave State.” Many of these caves contain fascinating and diverse formations, thanks to the state’s karst landscape of porous limestone and dolomite.
Stalactites, Stalagmites, and Columns
Stalactites are icicle-shaped formations that hang from a cave’s ceiling, while stalagmites are cone-shaped formations that rise from the floor. Both form due to the slow dripping of mineral-rich water. When stalactites and stalagmites eventually meet and grow together, they create columns that serve as natural pillars within the cave system.
Soda Straws and Helictites
Soda straws are a type of delicate, hollow stalactite. They form as mineral-rich water drips from the cave’s ceiling and leaves behind thin, tube-like structures. Over time, the tubes can become blocked with minerals, leading to the growth of solid stalactites.
Helictites are twisted, curving formations that can grow in any direction within a cave. Their unusual shapes are a result of capillary forces and hydrostatic pressure causing the mineral-rich water to flow in unexpected paths, creating these distinctive features.
Flowstones, Draperies, and Angel Showers
Flowstones are formed by the movement of water over cave walls and floors, allowing thin layers of minerals to be deposited over time. This process creates a smooth or rippled layer of stone that resembles cascading water.
Draperies, also known as cave bacon or curtain formations, are thin sheets of mineral deposits that hang from cave ceilings or walls. They form from water running down inclined surfaces, leaving behind layers of minerals resembling curtains or folded fabric.
Angel showers are a unique and rare type of cave formation found primarily in Missouri caves. They consist of clusters of stalactites suspended from a single point on the cave ceiling, resembling a collection of hanging icicles. These delicate formations take thousands of years to develop and are a breathtaking sight to behold.
The diverse and intriguing array of cave formations in Missouri attracts visitors, spelunkers, and researchers alike, showcasing the state’s geological wonders and contributing to its rich natural heritage.
