Tennena Cone

Tennena Cone, or Icebridge Cone, is a small volcanic cone on the upper western flank of Ice Peak, the south peak of Mount Edziza in northwestern British Columbia. Rising 2,390 metres within the Snowshoe Lava Field and largely encircled by the Mount Edziza ice cap, it is a visually striking, dark, pyramid-like landform. Part of the long-lived Mount Edziza volcanic complex, it formed much more recently, probably within the last 33,000 years, when basaltic magma erupted beneath thick glacial ice. That subglacial eruption produced distinctive volcanic deposits and lava features shaped by meltwater and ice, making the cone an unusually clear example of volcano formation under heavy glaciation.
