Riverbluff Cave facts for kids
The Riverbluff Cave is an amazing place where scientists study ancient life. It was found in the United States, near Springfield, Missouri. This cave is like a time capsule, holding secrets from hundreds of thousands of years ago!
The entrance to the cave is beautiful, filled with natural rock formations called stalactites (which hang from the ceiling) and stalagmites (which grow from the floor). Sometimes, these even join together to form tall columns.
Scientists believe Riverbluff Cave is about 830,000 years old. This makes it the oldest known cave in the U.S. that contains fossils! The cave itself is about 2,000 feet long.

Riverbluff Cave was found by accident on September 11, 2001. Engineers were using explosives to clear land for a new road when they uncovered the hidden entrance. It was a huge surprise and an exciting discovery for scientists!
What Makes Riverbluff Cave Special?
This cave is incredibly important because it contains many Pleistocene fossils. The Pleistocene is often called the "Ice Age." During this time, huge animals roamed the Earth.
Ancient Animals and Fossils
One of the most famous fossils found here is from the short-faced bear. This bear, known as Arctodus simus, was one of the largest bear species ever. It could stand about 5 to 6 feet tall at the shoulder and weigh around 2,000 pounds! Imagine seeing a bear that big!
The Cave's Formation
Riverbluff Cave is located in a special type of landscape called karst. This means the ground is made of soft rock, like limestone, that water can easily dissolve. The cave formed over many years as water slowly carved out tunnels and rooms in the ancient Mississippian limestone of the Ozarks region.
Visiting the Cave (Virtually!)
Even though Riverbluff Cave is not open to the public to protect its precious fossils, you can still explore it! There are virtual tours available on YouTube that let you see inside this incredible ancient world.
Close to the cave, there is also a museum. This museum displays many interesting rocks and fossils found in the area, giving you a closer look at the history of the Earth.
