🌋 Nanook Dome

Nanook Dome is a rounded mass of rock on the southeastern rim of Mount Edziza's summit crater in northwestern British Columbia, Canada. It has an elevation of 2,710 metres, slightly lower than the pinnacles on the southern crater rim which represent the highest points of Mount Edziza. The dome is about 750 m (2,460 ft) in diameter, almost circular in structure and contains steep, smooth convex margins that reach heights of 150–200 m (490–660 ft). Its northeastern side is truncated by the headwall of an immense cirque containing Tenchen Glacier, but the current structure of the dome is nevertheless almost identical to its original form.
