Nature
Tenchen Glacier lies on the eastern flank of Mount Edziza in northwestern British Columbia, within a large cirque cut into the volcano’s summit crater. Icefalls drop about 300 metres over cliffs from the breached crater rim, and meltwater drains through Tenchen Creek to Kakiddi Creek. The glacier is completely mantled in rock debris from ongoing landsliding, matching a Tahltan-derived name meaning dirty ice. Its setting records both erosion and an earlier explosive eruption that removed part of the eastern crater rim, exposing hydrothermally altered rocks and lava lakes of the Edziza Formation. Tenchen Glacier is notable for the rugged meeting of volcanic landforms, erosion, and ice.
