**Tenchen Glacier** is located on the eastern flank of [Mount Edziza](/source/Mount_Edziza) in northwestern [British Columbia](/source/British_Columbia), Canada. It lies within an immense [cirque](/source/Cirque) whose [headwall](/source/Headwall) has breached the eastern side of Mount Edziza's summit [crater](/source/Volcanic_crater). At the head of Tenchen Glacier are [icefalls](/source/Icefall) that drape down shear, 300-metre-high (980-foot) cliffs from the breached eastern crater rim; permanent ice fills the summit crater.[2] Meltwater from Tenchen Glacier feeds [Tenchen Creek](/source/Tenchen_Creek) which eventually merges with [Kakiddi Creek](/source/Kakiddi_Creek).[3]

The name of the glacier was suggested by the [Geological Survey of Canada](/source/Geological_Survey_of_Canada) on November 19, 1979, and eventually became official on November 24, 1980. *Tenchen* is derived from the [Tahltan](/source/Tahltan) words *ten* and *chen*, which mean *ice* and *dirty* respectively. The name of this glacier is a reference to its debris-covered surface.[1]

## Geology

The Tenchen cirque is the product of erosion that gradually enlarged an initial scar formed by an [explosive eruption](/source/Explosive_eruption) that blew away part of the eastern summit crater rim. [Hydrothermally altered](/source/Hydrothermally_altered) rocks of the central volcanic conduit as well as [lava lakes](/source/Lava_lake) that once filled the summit crater are exposed in the headwall of Tenchen cirque. These rocks are part of the [Edziza Formation](/source/Edziza_Formation) which comprises the central [stratovolcano](/source/Stratovolcano) of Mount Edziza.[2] Landsliding of the steep headwall and bounding spurs of Tenchen cirque has resulted in Tenchen Glacier being completely covered by rock debris.[1]
