Spectrum Range

The Spectrum Range, formerly called the Spectrum Mountains and the Rainbow Mountains, is a subrange of the Tahltan Highland in the Stikine Country of northwestern British Columbia, 20 km west of the Stewart-Cassiar Highway, south of Mount Edziza and north of the Arctic Lake Plateau. The Spectrum Range falls within Mount Edziza Provincial Park. The range is lightly glaciated, as compared to the other ranges to the west. It is accessible only by foot or via helicopter; there are no roads to the range.

The Pyramid, also called Pyramid Dome, is a young lava dome on the northeast flank of Mount Edziza in British Columbia, Canada. It is on the northeastern edge of the Tencho Glacier and represents several different styles of volcanic activity on the Mount Edziza complex. It is in the Northern Cordilleran Volcanic Province and last erupted during the Pleistocene period.

Ember Ridge is a volcanic mountain ridge associated with the Mount Cayley volcanic field in British Columbia, Canada. Ember Ridge is made of a series of steep-sided domes of glassy, complexly jointed, hornblende-phyric basalt with the most recent eruptions during the Holocene. The domes have structural similarities which indicate that the domes are similar in age and could have formed by the same foundation.

Slag Hill

Slag Hill is a subglacial volcano associated with the Mount Cayley volcanic field in British Columbia, Canada. It consists of glassy, augite-phyric basaltic andesite in steep-sided, glassy, finely jointed domes and one small, flat-topped bluff. The finely jointed domes are similar to those of Ember Ridge. There are quench features at Slag Hill, which is suggesting that the volcanic activity was subglacial. Slag Hill was formed throughout the Pleistocene period, but its most recent volcanic activity produced a lava flow on its western lobe that shows no evidence of ice-contact volcanism. This indicates the lava flow was erupted less than 10,000 years ago after the last glacial period.

Cauldron Dome is a tuya in the Mount Cayley volcanic field, British Columbia, Canada. Cauldron Dome is made of coarsely plagioclase-orthophyroxene-phyric andesite lava flows and last erupted during the Holocene. It is in the Garibaldi Volcanic Belt, a portion of the Canadian Cascade Arc.

Yeda Peak is a volcano and the highest peak of the Spectrum Range in the Boundary Ranges of northwestern British Columbia, Canada, located 57 km (35 mi) southwest of Tatogga and 5 km (3 mi) south of Kitsu Peak. It is believed Yeda Peak last erupted during the Pliocene period.

Nahta Cone

Nahta Cone is a cinder cone in northern British Columbia, Canada, located 69 km (43 mi) southwest of Tatogga, 9 km (6 mi) north of Wetalth Ridge and south of Telegraph Creek. It lies in the southwestern corner of Mount Edziza Provincial Park.

Outcast Hill is an isolated hill in northern British Columbia, Canada, located southeast of Mess Lake. It lies at the southern end of Mount Edziza Provincial Park.

Pali Dome

Pali Dome is a subglacial volcano in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is part of the Mount Cayley volcanic field and its elevation is 2,250 m (7,380 ft). For the past 2 million years, the Mount Cayley volcanic field has had interactions between ice and lava which have created some unique landforms and an in-ice drainage system."Pali" comes from the Hawaiian word that means cliff or steep hill, while dome refers to the lava dome, which is when doughy lava flows from a volcanic vent which is usually rounded and flat on top.

Triangle Dome is a trachytic lava dome in northern British Columbia, Canada. It is thought to have formed in the Pleistocene period.

Mount Edziza volcanic complex Mountain in British Columbia, Canada

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.

IGC Centre is a lava dome in Mount Edziza Provincial Park of northern British Columbia, Canada. It is thought to have formed and last erupted during the Miocene period.

Sezill Volcano is a lava dome in Mount Edziza Provincial Park of northern British Columbia, Canada. It is thought to have formed and last erupted during the Miocene period. The volcano gets its name from being adjacent to Sezill Creek.
