**Nanook Dome** is a rounded mass of rock on the southeastern rim of [Mount Edziza](/source/Mount_Edziza)'s summit [crater](/source/Volcanic_crater) in northwestern [British Columbia](/source/British_Columbia), Canada. It has an [elevation](/source/Elevation) of 2,710 metres (8,890 feet), slightly lower than the [pinnacles](/source/Pinnacle_(geology)) on the southern crater rim which represent the highest points of Mount Edziza. The dome is about 750 m (2,460 ft) in diameter, almost circular in structure and contains steep, smooth [convex](https://en.wiktionary.org/wiki/convex) margins that reach heights of 150–200 m (490–660 ft). Its northeastern side is truncated by the [headwall](/source/Headwall) of an immense [cirque](/source/Cirque) containing [Tenchen Glacier](/source/Tenchen_Glacier), but the current structure of the dome is nevertheless almost identical to its original form.

Nanook Dome is one of three [lava domes](/source/Lava_dome) defined as part of the [Edziza Formation](/source/Edziza_Formation), which is one of many [geological formations](/source/Geological_formation) comprising the [Mount Edziza volcanic complex](/source/Mount_Edziza_volcanic_complex). The dome consists mainly of [trachyte](/source/Trachyte) that erupted as viscous [lava](/source/Lava) from a vent on the southwestern rim of Mount Edziza's summit crater. Some of the lava from this vent flowed into the crater where it ponded to form one or more [lava lakes](/source/Lava_lake). Nanook Dome may have also been the source of some trachyte [lava](/source/Lava) flows of the [Kakiddi Formation](/source/Kakiddi_Formation), which exist in neighbouring valleys. [Volcanism](/source/Volcanism_of_the_Mount_Edziza_volcanic_complex) at the dome took place mainly during the [Pleistocene](/source/Pleistocene), as did other domes of the Edziza Formation.

## Name and etymology

The name of the dome became official on January 2, 1980, and was adopted on [National Topographic System](/source/National_Topographic_System) map 104G/10 after being submitted to the [BC Geographical Names](/source/BC_Geographical_Names) office by the [Geological Survey of Canada](/source/Geological_Survey_of_Canada).[2][9] Nanook Dome is named after the hereditary head of a [Tahltan](/source/Tahltan) family, but the name or title is said to be of [Tlingit](/source/Tlingit) origin, meaning 'chief'.[10][3] Several features adjacent to Nanook Dome also have names that were adopted simultaneously on 104G/10 for [geology](/source/Geology) reporting purposes; this includes [Ice Peak](/source/Ice_Peak), [Tennena Cone](/source/Tennena_Cone) and the [Ornostay](/source/Ornostay_Bluff) and [Koosick](/source/Koosick_Bluff) bluffs.[5][11][12][13][14] BC Geographical Names describes a dome as a "mass of rock or ice with a rounded top, elevated above the surrounding terrain".[2]

## Geography

Nanook Dome is located in [Cassiar Land District](/source/Cassiar_Land_District) of northwestern [British Columbia](/source/British_Columbia), Canada, about 23 km (14 mi) southeast of [Buckley Lake](/source/Buckley_Lake_(British_Columbia)).[2][5][15] It has an [elevation](/source/Elevation) of 2,710 m (8,890 ft) and forms the southeastern buttress of [Mount Edziza](/source/Mount_Edziza)'s ice-filled summit [crater](/source/Volcanic_crater).[1][16] The dome is about 750 m (2,460 ft) in diameter and is almost circular in structure, containing steep, smooth [convex](https://en.wiktionary.org/wiki/convex) margins that reach heights of 150–200 m (490–660 ft).[8] The northeastern side of Nanook Dome is truncated by the [headwall](/source/Headwall) of an immense [cirque](/source/Cirque) containing [Tenchen Glacier](/source/Tenchen_Glacier), but the current structure of the dome is nevertheless almost identical to its original form.[5][8]

Immediately west of Nanook Dome are several [spires](/source/Pinnacle_(geology)) on the southern rim of Mount Edziza's summit crater.[17] The highest of these spires attains an elevation of 2,786 m (9,140 ft), making it the highest point of Mount Edziza.[18][19] Mount Edziza is the highest [volcano](/source/Volcano) of the [Mount Edziza volcanic complex](/source/Mount_Edziza_volcanic_complex), which consists of a group of overlapping [shield volcanoes](/source/Shield_volcano), [stratovolcanoes](/source/Stratovolcano), [lava domes](/source/Lava_dome) and [cinder cones](/source/Cinder_cone) that have formed over the last 7.5 million years.[18][20] Nanook Dome is one of several lava domes on the summit and flanks of Mount Edziza; others include [The Pyramid](/source/The_Pyramid_(British_Columbia)) and the [Glacier](/source/Glacier_Dome), [Sphinx](/source/Sphinx_Dome) and [Triangle](/source/Triangle_Dome) domes.[5][21]

Nanook Dome lies in [Mount Edziza Provincial Park](/source/Mount_Edziza_Provincial_Park) southeast of the community of [Telegraph Creek](/source/Telegraph_Creek).[2] With an area of 266,180 hectares (657,700 acres), Mount Edziza Provincial Park is one of the largest [provincial parks in British Columbia](/source/Provincial_parks_in_British_Columbia) and was established in 1972 to preserve the volcanic landscape.[22][23] It includes not only the Mount Edziza area but also the [Spectrum Range](/source/Spectrum_Range) to the south, both of which are separated by [Raspberry Pass](/source/Raspberry_Pass).[22][24] Mount Edziza Provincial Park is in the [Tahltan Highland](/source/Tahltan_Highland), a southeast-trending [upland](/source/Upland_and_lowland) area extending along the western side of the [Stikine Plateau](/source/Stikine_Plateau).[24][25]

## Geology

Nanook Dome is the largest of three lava domes defined as part of the [Edziza Formation](/source/Edziza_Formation), one of many [stratigraphic units](/source/Stratigraphic_unit) comprising the Mount Edziza volcanic complex.[5][8] Its formation began during the later stages of the [Edziza eruptive period](/source/Volcanism_of_the_Mount_Edziza_volcanic_complex#Edziza_eruptive_period) 0.9 million years ago when viscous trachytic lava issued rapidly from a vent on the southwestern rim of Mount Edziza's summit crater.[26] Accompanying the development of Nanook Dome was the effusion of lava that flowed into the summit crater; the ponding of this lava inside the summit crater resulted in the formation of one or more [lava lakes](/source/Lava_lake).[27] A fuming vent inside the summit crater was effectively sealed by the lava which was soon followed by a small [phreatic explosion](/source/Phreatic_explosion) after lava had solidified. This explosion destroyed part of the eastern crater rim, providing a new passageway for the venting of [volcanic gases](/source/Volcanic_gas).[6] Nanook Dome has not erupted since the [Pleistocene](/source/Pleistocene) epoch, nor have the Glacier and Triangle domes which are also part of the Edziza Formation.[7][28][29][30]

Nanook Dome may have been a major source of the adjacent valley-filling trachyte lava flows of the [Kakiddi Formation](/source/Kakiddi_Formation) due to their [lithological](/source/Lithological) similarity and close spatial association.[31] Canadian volcanologist [Jack Souther](/source/Jack_Souther) supposed in 1992 that the Nanook stage of activity began with the eruption of voluminous, relatively fluid, [volatile](/source/Volatile_(astrogeology))-rich trachytic lava which may have been followed by collapse of Mount Edziza's summit to form the current ice-filled crater.[32] However, trachyte of the Edziza and Kakiddi formations have yielded significant differences in age; a single [potassium–argon date](/source/Potassium%E2%80%93argon_date) of 0.9 ± 0.3 million years has been obtained from [pantelleritic](/source/Pantelleritic) trachyte of the Edziza Formation whereas potassium–argon dates of 0.30 ± 0.02 million years and 0.28 ± 0.2 million years have been obtained from trachyte and pantelleritic trachyte of the Kakiddi Formation, respectively.[33] The Kakiddi Formation may nevertheless be similar in age to the youngest parts of the Edziza Formation.[34]
