Bohemia Ecological Preserve

This big Chert boulder is on the trail to Top-of-the-World about 50' above 4 Corners. Chert is a sedimentary rock that is brick red here, but can be many colors. It is often formed under the ocean from layers of fossilized radiolarian organisms. High pressure can create green and other colored minerals. (Chlorite, epidote and serpentine are green.)
