Spectrum Range

The Spectrum Range is a small mountain range in Cassiar Land District of northwestern British Columbia, Canada. Located on the Tahltan Highland, it borders the Skeena Mountains in the east and the Boundary Ranges of the Coast Mountains in the west. The range reaches an elevation of 2,430 metres (7, 970 feet) at Kitsu Peak and is surrounded by the Arctic Lake Plateau in the southwest and the Kitsu Plateau in the northwest. It lies at the southern end of the Mount Edziza volcanic complex, which includes the two neighbouring plateaus and the Big Raven Plateau to the north. The range contains glaciers and is drained on all sides by streams within the Stikine River watershed. It is characterized by multi-coloured rocks, after which the range is named. Mount Edziza Provincial Park is the only protected area surrounding the range. The Spectrum Range is the eroded remains of a large lava dome whose original surface is only preserved as a few small remnants on the summits of the higher peaks. This dome, originally more than 25 kilometres (16 miles) wide, formed between 3.5 and 2.5 million years ago during the second magmatic cycle of the Mount Edziza volcanic complex. Much of the dome consists of massive rhyolite and trachyte lava flows, but relatively minor basalt flows erupted later during the dome's formation. These lava flows form the nearly circular group of pyramidal peaks and long, narrow-crested ridges comprising the range; the basalt flows mainly cap the higher peaks. Volcanis
