Obsidian is a naturally occurring volcanic glass that is formed when lava cools rapidly with minimal crystal growth. It is usually black in color but can also appear in shades of brown, green, or even red. Obsidian has a smooth and glassy texture and can be easily fractured to create sharp edges.

2. Why is obsidian found in Colorado?
Colorado has a rich geological history and is home to several volcanic regions. These volcanic areas, such as the San Juan Mountains and the Raton-Clayton volcanic field, have provided the necessary conditions for the formation of obsidian. The volcanic activity in these regions occurred millions of years ago, leaving behind deposits of obsidian.
