16-589: The Nido Formation takes its name from Nido Creek , a stream flowing northeast from the eastern flank of Mount Edziza into Nuttlude Lake. Nido means "white man" in the Tahltan language . The Nido Formation has a volume of 127 km (30 cu mi), making it the second most voluminous geological formation of the Mount Edziza volcanic complex after the Armadillo Formation . It overlies

32-609: Is a tributary of Kakiddi Creek and part of the Stikine River watershed in northwest part of the province of British Columbia , Canada . It flows from Mount Edziza generally east for roughly 11 km (6.8 mi) to empty into Nuttlude Lake, an expansion of Kakiddi Creek , a tributary of the Klastline River , which in turn is a tributary of the Stikine River. Nido Creek's mean annual discharge

48-565: 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. Tennaya Creek is in Mount Edziza Provincial Park and the Tenh Dẕetle Conservancy , both of which lie within the traditional territory of the Tahltan people. Tennaya Creek originates from the eastern slope of Mount Edziza , a massive glaciated mountain in

64-410: Is estimated at 0.375 m /s (13.2 cu ft/s). Its watershed covers 19.2 km (7.4 sq mi) and is entirely within Mount Edziza Provincial Park and Tenh Dẕetle Conservancy . The watershed's land cover is classified as 33.8% barren , 30.1% conifer forest , 14.8% herbaceous , 13.7% shrubland , 7.3% snow / glacier , and small amounts of other cover. The mouth of Nido Creek

80-576: Is just north of the mouth of Tennaya Creek . Nido Creek's watershed is within the Mount Edziza volcanic complex . Tennaya Creek 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

96-471: Is located about 47 km (29 mi) southeast of Telegraph Creek , British Columbia, about 85 km (53 mi) south of Dease Lake , British Columbia, and about 245 km (152 mi) southeast of Juneau, Alaska . Nido Creek is in Mount Edziza Provincial Park and the Tenh Dẕetle Conservancy , both of which lie within the traditional territory of the Tahltan First Nation , of

112-482: The Big Raven Formation occur in two cirques at the head of Tennaya Creek. Icefall Cone on the northeast spur of Tennaya Cirque is completely buried under glacial ice and moraine . Ridge Cone is largely covered by permanent snow and lies on the western rim of Idiji Cirque. Both cones produced lava flows but are now almost completely covered by talus , moraine, fluvial gravel and glacial ice. Most of

128-695: The Raspberry , Armadillo and Little Iskut formations, all of which are Miocene in age. Also underlying the Nido Formation are pre- Tertiary rocks of the Stikinia terrane . Overlying the Nido Formation are the Spectrum, Pyramid , Ice Peak, Edziza and Big Raven formations which are of Pliocene age and younger. Two subunits comprise the Nido Formation, namely the Tenchen Member and

144-482: The Tahltan people. The name "Nido" is recorded as being a Tahltan word for "white man". It is the location of a number of mineral claims which were staked before this creek was given provincial park status. Nido Creek originates from the many glaciers on the east side of Mount Edziza and Nanook Dome . From its source, Nido Creek flows east for about 11 km (6.8 mi) before emptying into Nuttlude Lake, an expansion of Kakiddi Creek . The mouth of Nido Creek

160-506: The Klastline River. Tennaya Creek's watershed covers 63.3 km (24.4 sq mi) and its mean annual discharge is estimated at 1.50 m /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

176-776: The Kounugu Member. Both members are separated by the Armadillo Highlands in the middle of the Mount Edziza volcanic complex. The Tenchen Member forms a lava field north of the Armadillo Highlands while the Kounugu Member forms a lava field south of the highlands. The Nido Formation consists of alkali basalt and hawaiite lava flows that issued from multiple eruptive centres. K–Ar dating has yielded ages of 7.8 ± 0.3 million years, 5.5 ± 1.6 million years, 4.5 ± 0.3 million years and 4.4 ± 0.5 million years for Nido alkali basalt. Nido Creek Nido Creek

192-530: The emplacement of the older Ice Peak Formation. They instead probably issued from vents in or adjacent to the valleys containing them. A nearly 1 km (0.62 mi) wide and 60–120 m (200–390 ft) thick trachyte flow of the Kakiddi Formation forms a flat interfluve between the lower reaches of Sorcery and Tennaya creeks. It probably issued from Ice Peak or Nanook Dome on the southeastern rim of Mount Edziza. Two small volcanic cones of

208-476: The head of Tennaya Creek are four active cirques exposing the internal structure of Ice Peak , an eroded stratovolcano predating the main edifice of Mount Edziza. Exposed in the steep headwalls of these cirques are thick flows of trachyte and pyroclastic breccia belonging to the Ice Peak Formation. Tennaya Creek has also cut through the base of the volcano, resulting in deep dissection of

224-532: The lava from these cones probably cascaded down the steep Tennaya and Idiji cirque headwalls into Tennaya Creek valley. The north side of Tennaya Creek contains a zone of mineralization called the West Creek occurrence or West Creek showing. It includes a 1.2 m-wide (3.9 ft) quartz vein carrying pyrite , chalcopyrite and sphalerite . Sampling of this vein in 2016 returned values in gold , silver and copper . The field name for Tennaya Creek

240-495: The middle of the Big Raven Plateau . From its source, Tennaya Glacier, Tennaya Creek flows about 6 km (3.7 mi) southeast through a vegetated canyon. Tennaya Creek then flows east through the canyon for another 1 km (0.62 mi) before entering Kakiddi Valley where it flows an additional 8 km (5.0 mi) northwest into the southwestern end of Nuttlude Lake , an expansion of Kakiddi Creek. At

256-562: The underlying basement rocks . A 120 m-thick (390 ft) diabase intrusion is exposed along the northwestern headwall of Tennaya Creek for about 1.5 km (0.93 mi); it is the largest subvolcanic intrusion related to the Ice Peak volcano. Trachyte flows of the younger Kakiddi Formation occur in the south forks of Tennaya Creek. The source of these lava flows was originally thought to be The Neck , but radiometric dating of this volcanic plug suggests that it formed during
