Obsidian

Obsidian is commonly known as volcanic glass. It forms when a volcano erupts and the lava is cooled extremely quickly, such as when it flows into a water body. In Alberta obsidian is considered to be an “exotic material” because it does not occur here naturally. When we find it here it tells us that people in the past engaged in long distance trade, usually with people in British Columbia or the Yukon. In 2016 Teresa found this lovely obsidian flake at site FaPr-6 located near the community of Caroline.
