**Tencho Glacier** is a [mountain glacier](/source/Mountain_glacier) in northwestern [British Columbia](/source/British_Columbia), Canada. It is located inside [Mount Edziza Provincial Park](/source/Mount_Edziza_Provincial_Park) on the [Tahltan Highland](/source/Tahltan_Highland), an upland area of the [Stikine Plateau](/source/Stikine_Plateau).[2][3] Tencho Glacier is the source of several small streams that flow from the [Mount Edziza volcanic complex](/source/Mount_Edziza_volcanic_complex).

## Etymology

The name of the glacier was suggested by the [Geological Survey of Canada](/source/Geological_Survey_of_Canada) on November 15, 1979, and eventually became official on November 24, 1980. *Tencho* is derived from the [Tahltan](/source/Tahltan) words *ten* and *cho*, which mean *ice* and *big* or *great* respectively. This glacier is so-named because it is the largest glacier of the Mount Edziza volcanic complex.[1]

## Geography

Tencho Glacier originates from [Ice Peak](/source/Ice_Peak) and [Tennena Cone](/source/Tennena_Cone) on the southern flank of [Mount Edziza](/source/Mount_Edziza).[2][4] Its southern terminus is surrounded by Kaia Bluff in the southeast, [Coffee Crater](/source/Coffee_Crater) in the south and [Cocoa Crater](/source/Cocoa_Crater) in the southwest. Unnamed [tributaries](/source/Tributaries) of [Taweh Creek](/source/Taweh_Creek) originate from the southwestern side of Tencho Glacier between Cocoa Crater and Coffee Crater. [Shaman Creek](/source/Shaman_Creek) originates from the southern end of Tencho Glacier whereas the eastern side of Tencho Glacier is drained by unnamed tributaries of [Tennaya Creek](/source/Tennaya_Creek).[2] Several unnamed tributaries of [Sezill Creek](/source/Sezill_Creek) originate from the western side of Tencho Glacier by Tennena Cone.[2][4]

## Geology

Tencho Glacier overlies the [Ice Peak Formation](/source/Ice_Peak_Formation), one of several [geological formations](/source/Geological_formation) comprising the Mount Edziza volcanic complex.[5][6] [Obsidian](/source/Obsidian) of the Ice Peak Formation occurs east and west of Tencho Glacier and possibly extends under the glacier.[6] [Beds](/source/Bed_(geology)) of coarse [comenditic](/source/Comenditic) [trachyte](/source/Trachyte) [pumice](/source/Pumice) belonging to the [Sheep Track Member](/source/Sheep_Track_Member) of the [Big Raven Formation](/source/Big_Raven_Formation) are exposed along the western edge of Tencho Glacier. They are up to 2 metres (6.6 feet) thick and were deposited by an eruption that probably originated from a deep, circular depression on the surface of Tencho Glacier north of Coffee Crater. A crescent-shaped ridge at the southern terminus of Tencho Glacier might be a glacially modified [tuff ring](/source/Tuff_ring) that formed in a meltwater lake when the glacier extended onto the [Big Raven Plateau](/source/Big_Raven_Plateau).[5]
