Mount Edziza volcanic complex
The Mount Edziza volcanic complex is a large and potentially active north-south trending complex volcano in Stikine Country, northwestern British Columbia, Canada, located 38 kilometres (24 mi) southeast of the small community of Telegraph Creek. It occupies the southeastern portion of the Tahltan Highland, an upland area of plateau and lower mountain ranges, lying east of the Boundary Ranges and south of the Inklin River, which is the east fork of the Taku River. As a volcanic complex, it consists of many types of volcanoes, including shield volcanoes, calderas, lava domes, stratovolcanoes, and cinder cones.Most of the Mount Edziza volcanic complex is encompassed within a large provincial park called Mount Edziza Provincial Park. Named after Mount Edziza, this 2,660.95 km2 (1,027.40 sq mi) park was established in 1972 to preserve the volcanic and cultural treasures unique to the northern British Columbia area. The Mount Edziza volcanic complex is remote, and, without roads, accessible only along trails. The easiest access is from Highway 37 and a spur road from Dease Lake to Telegraph Creek. From Kinaskan Lake, on Highway 37, a poorly maintained trail extends west for 30 kilometres (19 mi) into the heart of the complex. From Telegraph Creek another trail extends east for 25 kilometres (16 mi) to the north slope of Mount Edziza.
