Geological Summary

The Squamish volcanic field contains the southernmost vents of the Garibaldi volcanic belt. Late Pleistocene eruptions formed The Castle, a dramatic strongly jointed spire above the town of Squamish formed by ice contact lava extrusion (Mathews, 1958), and Watts Point, on Howe Sound south of Squamish, formed by subglacial valley floor lava extrusion. The dacite flows at Watts Point are Potassium-Argon dated at 0.09 and 0.13 million years (Green et al., 1988).

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Squamish. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Squamish page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is no Deformation History data available for Squamish.

Emission History

There is no Emissions History data available for Squamish.
