Exploring Idaho’s Caves
Idaho is well known for its majestic mountains, sprawling rivers, and vast wilderness areas. However, beneath its scenic landscapes lies a hidden world waiting to be explored: its caves. These subterranean marvels offer unique opportunities for adventure, scientific discovery, and an appreciation of the natural forces that shape our planet. This article will guide you through some of Idaho’s most fascinating caves, their geological significance, and what explorers can expect to observe when they visit.
The Significance of Idaho’s Caves
Caves are natural voids in the ground, typically formed through the erosion of limestone by acidic water over thousands to millions of years. Idaho’s caves are primarily volcanic or limestone caves, resulting from different geological processes. Volcanic caves, also known as lava tubes, form from flowing lava that cools and solidifies on the surface while the molten lava beneath continues to flow, eventually draining away and leaving a hollow tube. Limestone caves form from the slow dissolution of carbonate rock by slightly acidic groundwater.
Craters of the Moon National Monument & Preserve
Craters of the Moon, located in south-central Idaho, is a vast volcanic landscape featuring lava flows, cinder cones, and, notably, a number of fascinating lava tubes. This unique area provides a glimpse into Idaho’s volcanic past and offers several caves that are open to the public.
Indian Tunnel
Indian Tunnel is one of the most accessible caves in the Craters of the Moon. It is a large, 800-foot-long lava tube that doesn’t require technical equipment to explore. The tunnel features a partially collapsed roof that allows natural light to illuminate much of the cave, making it easier to navigate. Visitors can traverse the cave and emerge at the other end, marveling at the textures and formations created by ancient lava flows.
Dewdrop Cave, Boy Scout Cave, and Beauty Cave
These three smaller caves within Craters of the Moon offer more challenging adventures. Dewdrop Cave has a small entrance and features beautiful ice formations in the winter. Boy Scout Cave is a bit more challenging, with a low entrance and rough floor, but it rewards explorers with its fascinating formations and cool interior. Beauty Cave, true to its name, showcases striking volcanic features and requires a bit of scrambling to explore fully.
Minnetonka Cave
Minnetonka Cave, located in the Cache National Forest located in southeastern Idaho, is one of the state’s largest and most spectacular limestone caves. Unlike the lava tubes of Craters of the Moon, Minnetonka Cave features impressive stalactites, stalagmites, and other speleothems (cave formations) created by the slow drip of mineral-rich water over millennia.
Visitors may choose to take guided tours of the cave, which covers nearly half a mile of passageways and descends approximately 400 feet underground. The tour includes several well-lit chambers, each with unique and awe-inspiring formations. Highlights include the Bridal Veil, a stunning drapery-like formation, and the Club Room, filled with stalactites and stalagmites that create an almost otherworldly atmosphere.
Shoshone Ice Caves
The Shoshone Ice Caves, located near the town of Shoshone in southern Idaho, are a fascinating example of a lava tube that contains year-round ice. The cave maintains a constant low temperature due to its unique airflow patterns, preserving large amounts of ice even during the hot summer months.
Visitors to the Shoshone Ice Caves can take guided tours that explain the cave’s geology and history. The tour takes you through the icy passages, where you can see impressive ice formations and learn about the early explorers and settlers who discovered and utilized the cave. The cave’s icy interior provides a stark contrast to the hot, arid landscape above, making it a unique and refreshing destination.
Kuna Caves
Kuna Caves, located near the town of Kuna in southwestern Idaho, is a lesser-known but intriguing lava tube system. The caves were formed by ancient lava flows from the nearby Black Butte Crater and offer an adventurous spelunking experience.
The entrance to Kuna Caves is a vertical shaft with a ladder that leads down into the darkness. Once inside, the cave extends for about a quarter of a mile, with passages that range from spacious to narrow and winding. The cave’s rough lava rock walls and ceilings are adorned with interesting textures and formations created by the cooling lava. While not as developed or well-known as some of Idaho’s other caves, Kuna Caves provide a more rugged and raw caving experience.
Wilson Butte Cave
Wilson Butte Cave, located near Twin Falls in southern Idaho, is both a geological wonder and an important archaeological site. The cave, formed by volcanic activity, contains evidence of human habitation dating back over 10,000 years. This makes it one of the oldest known habitation sites in North America.
The cave is situated on the Snake River Plain and features several chambers and passageways created by ancient lava flows. Archaeological excavations have uncovered a wealth of neat artifacts, including stone tools, pottery shards, and animal bones, providing valuable insights into the lives of Idaho’s early inhabitants. While the cave itself is not typically open for casual exploration, its historical significance and the surrounding landscape make it a fascinating destination for those interested in both geology and archaeology.
Darby Wind Cave
Darby Wind Cave, located in the Caribou-Targhee National Forest near the Idaho-Wyoming border, is a limestone cave known for its beautiful formations and challenging entrance. The cave is accessible via a moderately strenuous hike through the scenic Teton Mountains, adding an element of adventure to the visit.
The cave entrance is a narrow, windy passage that requires some scrambling to navigate. Inside, visitors are rewarded with stunning formations. The cool, damp interior of the cave provides a refreshing contrast to the hike, and the formations create a surreal, otherworldly atmosphere. Because of the cave’s remote location and challenging entrance, it’s less frequented, making it a great destination for those seeking a more solitary and adventurous caving experience.
Mammoth Cave
Mammoth Cave, located in the Shoshone Lava Field, is one of the longest lava tubes in Idaho. The cave stretches for over a quarter of a mile and features wide passages and interesting lava formations. Unlike some of the more rugged and technical caves, Mammoth Cave is relatively easy to explore, making it suitable for all-ages with accompanied with a guide and casual adventurers.
The cave remains at a constant cool temperature, offering a respite from the heat during the summer months. Guided tours are available, providing insights into the geological history of the area and the formation of the cave. The nearby Shoshone Bird Museum of Natural History adds an educational component to the visit, with exhibits on local wildlife and geology.
Clay Cave
Clay Cave, also located near the town of Shoshone, offers a less commercialized caving experience. This cave is part of a network of lava tubes in the area and provides a sense of exploration for those willing to venture off the beaten path. The cave is accessible via a small entrance that leads into a series of dark, winding passages.
Explorers will need to bring their own lighting and be prepared for a more challenging and adventurous experience. The cave’s name comes from its enigmatic formations and the sense of mystery that pervades the underground passages. It’s an ideal destination for experienced cavers looking for a more rugged and raw adventure.
Paris Ice Caves
Located in the southern part of Idaho, the Paris Ice Cave is a hidden gem for caving enthusiasts. These caves feature beautiful ice formations and a cool, refreshing climate. The caves are accessible via a short hike through the scenic trails, making them an ideal destination for a day trip.
Inside the dark caves, visitors can marvel at the intricate ice formations and the unique textures created by the flowing water and freezing temperatures. The caves offer a peaceful and serene environment, ideal for those searching to escape the summer heat and explore a lesser-known natural wonder.
Gooding City’s Tea Kettle Cave
Tea Kettle Cave, found in the Lost River Range, is a lava tube with a unique shape resembling a tea kettle. The cave’s entrance is a small, round hole that opens into a larger chamber with interesting lava formations. The cave’s distinctive shape and the surrounding landscape make it a popular destination for spelunkers and hikers alike.
