About Crow Lagoon
Crow Lagoon is a pyroclastic cone rising to 335 meters (1,099 feet) in Canada's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Crow Lagoon is located in Canada, within the Northern Cordilleran Volcanic Province of the broader North America Volcanic Regions. Situated at 54.70° N, 130.23° W in the Northern Hemisphere, the volcano lies within a temperate climate zone. At just 335 meters above sea level, Crow Lagoon is a relatively low-elevation volcanic feature. Despite its modest height, it remains an active geological formation with the same underlying magmatic processes as its taller counterparts. The volcanic landform is characterized as a minor, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Crow Lagoon is an intraplate volcano, meaning it formed away from any plate boundary. These volcanoes are often powered by hotspots — plumes of abnormally hot mantle material rising from deep within the Earth. Hotspot volcanoes like Crow Lagoon tend to produce effusive eruptions with lava flows that can be relatively predictable, giving nearby communities in Canada more time to prepare. However, they can also produce explosive phases, particularly when magma interacts with groundwater. The dominant rock type is basalt / picro-basalt, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
Thick deposits of Holocene basaltic tephra originating from an unknown volcanic center have been found near Crow Lagoon, ~40 km N of Prince Rupert near the southern tip of the SE Alaskan panhandle. The deposits are located along the S side of the Khutzeymateen Inlet. Ballistically emplaced bombs imply a nearby source, which remains unidentified (Souther and Weiland, 1993).
