The Coast Mountains are a Mountain range of the Pacific Cordillera, running along the north western shore of the North American continent extending south Portland Inlet is an Inlet of the Pacific Ocean on the coast of British Columbia, Canada, approximately 55 kilometers north of Prince Rupert The Pacific Ocean is the largest of the Earth 's Oceanic divisions Dixon Entrance is a Strait about long and wide in the Pacific Ocean at the International Boundary between the U

The last 40 km (25 miles) of the river are navigable. The river is a commercially-valuable salmon fishery. The basin of the Nass is the location of the first modern-day treaty settlement in British Columbia, between the government of that province and the Nisga'a Nation. The Nisga'a (nisqaʔa often formerly spelled Nishga and spelled in the Nisga'a language as Nisg̱a'a, are an Indigenous nation or Nisga'a means "people of the Nass".

History

About 220 years ago according to legend of the Nisga'a people, the Nass River was dammed by a 22. A dam is a barrier that divides waters. Dams generally serve the primary purpose of retaining water while other structures such as Floodgates, Levees 5 km long lava flow which came from the Tseax Cone and destroyed the Nisga'a villages and the death of at least 2000 Nisga'a people by volcanic gas and poisonous smoke. Lava is molten rock expelled by a Volcano during an eruption When first expelled from a volcanic vent it is a Liquid at Temperatures The Tseax Cone, also called the Tseax River Cone or the Aiyansh Volcano (pron Volcanic gases include a variety of substances given off by active (or at times by dormant Volcanoes These include gases trapped in cavities ( Vesicles) in The volcano was active at least twice (220 and 650 years ago). Because of our knowledge of this previous disaster, modern monitoring would include studies of the gases emitted by the volcanoes and a warning to people living downslope from the volcanoes.

Hazards

If the Tseax Cone were to erupt again, there would be a repeat of the poisonous gas disaster (as to what happened to the Nisga'a people) could cause forest fires and could poentially dam local rivers (as to what happened to the Tseax and Nass River) if the volume of the lava flows are large enough. The Tseax Cone, also called the Tseax River Cone or the Aiyansh Volcano (pron A wildfire, also known as a wildland fire, forest fire, brush fire, vegetation fire, grass fire, Peat fire, The Tseax River, aka Ksi Sii Aks in the Nisga'a language, is a tributary of the Nass River in northwestern British Columbia, Canada If the lava flows were to again reach the Nass River, it could have disastrous short-term consequences for the important salmon fisheries on the Nass River system. Salmon is the common name for several species of Fish of the family Salmonidae. For the fishing industry and the practice of fishing see Fishing. The people who live in the region would have no knowledge of the dangers of the Tseax Cone if they were to erupt again.
