Mount Cayley

Mount Cayley is a potentially active stratovolcano in southwestern British Columbia, formed over millions of years within the Garibaldi Volcanic Belt and later heavily reshaped by erosion and glaciers. Rather than a single cone, it survives as a rugged massif with three high summits, steep cliffs, lava domes, and jagged pinnacles. Although no historical eruptions are known, earthquakes, hot springs, and deep seismic evidence show that magmatic heat remains beneath the volcano, so it is monitored by the Geological Survey of Canada. Its greatest danger has often been collapse and debris avalanches, while the mountain also holds deep sacred significance for the Squamish people.
