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
[edit]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
[edit]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 glacial period.[2]
