Obsidian is a naturally occurring volcanic glass that is extremely sharp and durable. It was highly prized by these indigenous cultures for its versatility:
* Weapons: Obsidian's sharp edges made it perfect for creating arrowheads, spear points, knives, and other weapons.
* Tools: The material was also used for making scrapers, cutting tools, and other everyday implements.
* Jewelry: Obsidian's dark, glassy appearance made it attractive for crafting beads, pendants, and other forms of jewelry.
* Trade: Obsidian was a valuable commodity that was traded widely throughout the region, connecting different tribes and cultures.
The most famous source of obsidian in northeastern California is the Glass Mountain obsidian flow in Modoc County, which provided a high-quality material sought after by many groups.
