Idiji Glacier is one of several glaciers draining the eastern side of the Mount Edziza ice cap in northwestern British Columbia, Canada. It is located south of the summit of Mount Edziza in a cirque just southeast of Ice Peak. Idiji Glacier is separated from the much larger Tencho Glacier by a ridge that extends south of Ice Peak above the Idiji cirque headwall. Idiji Glacier is the namesake of Idiji Ridge which is just to the southeast. [2]

The name of the glacier was suggested by the Geological Survey of Canada on November 15, 1979, and eventually became official on November 24, 1980. Idiji means "it thunders" in the Tahltan language, which refers to the loud noises stemming from this very active glacier. [1]

At the head of Idiji Glacier are rocks assigned to the upper assemblage of the Ice Peak Formation. They consist of trachyte, benmoreite, mugearite, tristanite, trachybasalt and alkali basalt that are in the form of lava flows, lava domes and pyroclastic breccia. [2] Bedded, lacustrine tuff and epiclastic debris exposed in a rock spur on the north side of Idiji Glacier was deposited in a now-destroyed summit crater, of which Ice Peak is a remnant of the western crater rim.

Mount Edziza, known to the local Tahltan people as Tenh Dẕetle, is a volcanic mountain in Cassiar Land District of northwestern British Columbia, Canada. It is located on the Big Raven Plateau of the Tahltan Highland which extends along the western side of the Stikine Plateau. Mount Edziza has an elevation of 2,786 metres, making it the highest point of the Mount Edziza volcanic complex. However, it had an elevation of at least 3,396 metres before its formerly cone-shaped summit was likely destroyed by a violent eruption in the geologic past; its current flat summit contains an ice-filled, 2-kilometre-in diameter (1.2-mile) crater. The mountain contains several lava domes, cinder cones and lava fields on its flanks, as well as an ice cap containing several outlet glaciers which extend to lower altitudes. All sides of Mount Edziza are drained by tributaries of Mess Creek and Kakiddi Creek which are situated within the Stikine River watershed.

<span class="mw-page-title-main">Spectrum Range</span> Mountain range in British Columbia, Canada

The Spectrum Range, formerly gazetted as the Spectrum Mountains and the Rainbow Mountains, is a small mountain range in Cassiar Land District of northwestern British Columbia, Canada. Located at the southern end of the Tahltan Highland, it borders the Skeena Mountains in the east and the Boundary Ranges of the Coast Mountains in the west. The Spectrum Range is surrounded by the Arctic Lake Plateau in the southwest and the Kitsu Plateau in the northwest, both of which contain volcanic features such as cinder cones. It lies at the southern end of the Mount Edziza volcanic complex which includes the two neighbouring plateaus as well as Mount Edziza and the Big Raven Plateau to the north. The mountain range is drained on all sides by streams within the Stikine River watershed and, unlike Mount Edziza to the north, contains relatively small separate glaciers. Mount Edziza Provincial Park is the main protected area surrounding the Spectrum Range.

Nahta Cone is a small cinder cone in Cassiar Land District of northwestern British Columbia, Canada. It has an elevation of 1,670 metres and lies near the northern edge of the Arctic Lake Plateau, a glacially scored plateau of the Tahltan Highland which in turn extends along the western side of the Stikine Plateau. The cone is about 70 kilometres south-southeast of the community of Telegraph Creek and lies in the southwestern corner of Mount Edziza Provincial Park, one of the largest provincial parks in British Columbia.

<span class="mw-page-title-main">Big Raven Plateau</span> Plateau in British Columbia, Canada

The Big Raven Plateau is an intermontane plateau in Cassiar Land District of northwestern British Columbia, Canada. It lies on the Tahltan Highland and is surrounded by several valleys, including those of Mess Creek, Kakiddi Creek, Chakima Creek, Walkout Creek and the Klastline River. The plateau is drained by many small streams that flow into these neighbouring valleys and, unlike the valleys, it is relatively barren of vegetation. Stream erosion has resulted in the creation of canyons with intervening ridges on the eastern and western sides of the plateau, resulting in the creation of rugged terrain. The plateau is in Mount Edziza Provincial Park which is one of the largest provincial parks in British Columbia. Access to the Big Raven Plateau is mainly by aircraft or by a network of footpaths from surrounding roads.

<span class="mw-page-title-main">Big Raven Formation</span> Geological formation in British Columbia, Canada

The Big Raven Formation is a stratigraphic unit of Quaternary age in northwestern British Columbia, Canada. It is the youngest and least voluminous geological formation of the Mount Edziza volcanic complex (MEVC); it overlies at least six older formations of this volcanic complex. The main volcanic rocks of the Big Raven Formation are alkali basalts and hawaiites, although a small volume of trachyte comprises the Sheep Track Member. These rocks were deposited by volcanic eruptions in the last 20,000 years during the latest magmatic cycle of the MEVC. Alkali basalt and hawaiite are in the form of lava flows and small volcanic cones while trachyte of the Sheep Track Member is mainly in the form of volcanic ejecta which covers an area of about 40 square kilometres.

Tennaya Creek is a tributary of Kakiddi Creek, which in turn is a tributary of the Klastline River, part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally west for about 16 km (9.9 mi) to join Kakiddi Creek about 19 km (12 mi) south of Kakiddi Creek's confluence with the Klastline River. Tennaya Creek's watershed covers 63.3 km2 (24.4 sq mi) and its mean annual discharge is estimated at 1.50 m3/s (53 cu ft/s). The mouth of Tennaya Creek is located about 48 km (30 mi) southeast of Telegraph Creek, about 30 km (19 mi) southwest of Iskut and about 86 km (53 mi) south-southwest of Dease Lake. Tennaya Creek's watershed's land cover is classified as 31.3% barren, 26.0% conifer forest, 17.9% snow/glacier, 12.6% herbaceous, 9.9% shrubland, and small amounts of other cover.

Tenchen Creek is a tributary of Kakiddi Creek, which in turn is a tributary of the Klastline River, part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally flows northeast for about 8 km (5.0 mi) to join Kakiddi Creek about 13 km (8.1 mi) south of Kakiddi Creek's confluence with the Klastline River. Tenchen is a combination of the Tahltan words "ten" and "chen", which mean "ice" and "dirty" respectively.

<span class="mw-page-title-main">Tencho Glacier</span> Glacier in British Columbia, Canada

Tencho Glacier is a mountain glacier in northwestern British Columbia, Canada. It is located inside Mount Edziza Provincial Park on the Tahltan Highland, an upland area of the Stikine Plateau. Tencho Glacier is the source of several small streams that flow from the Mount Edziza volcanic complex.

Tenchen Glacier is located on the eastern flank of Mount Edziza in northwestern British Columbia, Canada. It lies within an immense cirque whose headwall has breached the eastern side of Mount Edziza's summit crater. At the head of Tenchen Glacier are icefalls that drape down shear, 300-metre-high (980-foot) cliffs from the breached eastern crater rim; permanent ice fills the summit crater. Meltwater from Tenchen Glacier feeds Tenchen Creek which eventually merges with Kakiddi Creek.

Tennaya Glacier is one of several glaciers draining the eastern side of the Mount Edziza ice cap in northwestern British Columbia, Canada. It is located southeast of the summit of Mount Edziza and northwest of Ice Peak at the head of Tennaya Creek. Meltwater from Tennaya Glacier feeds Tennaya Creek which eventually flows into Nuttlude Lake, an expansion of Kakiddi Creek.
