Crow Lagoon

Cono piroclástico · Canada · 335 m

A geologist observes the contact between a basaltic Plinian fallout lapilli unit overlying marine clay. This deposit is part of thick beds of basaltic Holocene tephra originating from an unknown Quaternary volcanic center found near Crow Lagoon, north of Prince Rupert near the southern tip of the Alaskan panhandle. Ballistically emplaced bombs imply a nearby source. The tephra beds are located along the south side of the Khutzeymateen Inlet, about 40 km N of Prince Rupert. · Foto: Photo by Jack Souther (Geological Survey of Canada, courtesy of Cathie Hickson).
