It occurs in at least four geological formations of the volcanic complex and was widely used by indigenous peoples during the pre-Columbian era.
[189] [190] It occurs over an area of more than 2,200,000 km 2 (850,000 sq mi), making MEVC obsidian the most widely distributed obsidian in western North America. [ 189 ] [ 191 ] Obsidian from the Hidden Falls archaeological site in Alaska has yielded a hydration date of 10,000 years; this suggests the MEVC was being exploited as an obsidian ...

Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
Obsidian from the Mount Edziza volcanic complex found in coastal areas of southeast Alaska. The MEVC lies within the traditional territory of the Tahltan people which covers an area of more than 93,500 square kilometres (36,100 square miles). [167] Historically, the MEVC was a significant source of obsidian for the Tahltan people.
Obsidian has also been found in Gilat, a site in the western Negev in Israel. Eight obsidian artifacts dating to the Chalcolithic Age found at this site were traced to obsidian sources in Anatolia. Neutron activation analysis (NAA) on the obsidian found at this site helped to reveal trade routes and exchange networks previously unknown. [52]

The Swan Point Archeological Site is located in eastern central Alaska, in the Tanana River watershed. It is one of a collection of sites in the area that have yielded the oldest evidence of human habitation in the state, in addition to megafauna no longer found in Alaska, such as wapiti (elk), bison, and woolly mammoth.
