Can You Dig It?
Between 1934 and 1940, the Civilian Conservation Corps (CCC) removed more than 3,000 dump truck loads of rock and debris from Longhorn Cavern. The CCC discovered beautiful calcite crystals, prehistoric fossils, and Native American artifacts.
Imagine you were here with the CCC. What will you discover?
How to Sluice
A sluice box uses running water to help separate rocks and minerals from the dirt around them. Here's how it works:
- Cut open your bag of mining rough.
- Pour the mining rough into the sluice basket.
- Place the basket into the water and move it side-to-side to sift away the sand and other small particles.
- Collect your treasures in the empty bag.
