Mount Edziza

Mount Edziza is a 2793 m high volcano in northwestern British Columbia, Canada and is part of the Boundary Range, as part of the Coast Mountains. It consists of a thin layer of basalt with a central dome of andesite, dacite and rhyolite. To the mountain was of 2660.95 km ² Mount Edziza Provincial Park, which is also the second largest volcanic complex of Canada, the Mount Edziza volcanic complex.

The volcanic area is about 7.5 million years old, the second phase of activity is back about 3.5 million years, the third about 1.6 million years. Only in the fourth phase before about a million years, the Mount Edziza arose. The fifth and so far last phase of activity took place around 10,000 years ago. It ended around 700 AD

Since the last outbreak he is a dormant volcano, but found some minor eruptions around him and so there are now more than 30 conical elevations in the vicinity of the volcano. Examples are the perfectly symmetrical volcanic cone Eve Cone, as the volcanic cones Coffee and Cocoa. Also indicate some hot springs on the western flank activity, as well as seismic measurements.

In addition, the volcano contains archaeological sites, demonstrate the trade in obsidian over long distances as early as about 8000 BC.

History

The obsidian mining in British Columbia since at least back to 8000 BC and was based on the deposit on Edziza, whose core area is about 1800 to 1900 m altitude. The tree line is around 1200 m.

For the Tahltan, the First Nation, who lives in the region, there are two sacred sites, the Tahltan Eagle at the point where the Stikine and Tahltan River flow together, and the 2251 m high Pipe Organ Mountain.

During the gold rush in the Klondike, a Yukon telegraph connection was in the vicinity of the mountain, which still shows up in the form of broken cable connections or some masts.

1981 first archaeological investigations were made under the direction of Knut R. Fladmark. He speculated that the mythological character named E'dista, a supernatural toad that breathed through holes in the mountains, back to the name of the mountain.
