'''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]].<ref name="SI"/>

==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.<ref name="SI">{{BCGNIS|16786|Pillow Ridge}}</ref>

==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 glacial period]].<ref>{{Cite web |url=http://gsc.nrcan.gc.ca/volcanoes/cat/volcano_e.php?id=svb_prg_082 |title=Catalogue of Canadian volcanoes: Pillow Ridge |access-date=2008-05-02 |archive-url=https://web.archive.org/web/20071110044032/http://gsc.nrcan.gc.ca/volcanoes/cat/volcano_e.php?id=svb_prg_082 |archive-date=2007-11-10 |url-status=dead }}</ref>
