Pillow Ridge is a ridge of the Tahltan Highland in northern British Columbia, Canada, located southeast of Telegraph Creek. It extends northwest from Mount Edziza in Mount Edziza Provincial Park.[1]

History

As its name suggests, Pillow Ridge was named on January 2, 1980 by the Geological Survey of Canada for the classic exposures of subaqueous pillow lava that form the ridge.[1]

Geology

Pillow Ridge is a volcanic feature associated with the Mount Edziza volcanic complex which in turn form part of the Northern Cordilleran Volcanic Province. It is a subglacial mound that formed in the Pleistocene period when this area was buried beneath glacial ice during the last ice age.[2]
