Thankfully no injuries were reported following a massive rockfall on one of the largest granite monoliths in the world.
The rocks fell from Stawamus Chief Mountain located inside Stawamus Chief Park near Valleycliffe neighbourhood of Squamish, British Columbia, Canada. A webcam captured the debris falling from the Zodiac Wall at 9:00 a.m.on Monday. The boulder that fell is estimated to have been 10 to 15 meters tall and five meters wide and five meters thick (500 or 1,000 cubic meters).
Another rockfall this morning on the Stawamus Chief, just after 9:00am. They never look quite as impressive in the daytime as they do at night with the sparks, but that's still a lot of rock coming down! #SquamishBC #StawamusChief #TheChief pic.twitter.com/zgNirnVmif

Residents of the Valleycliffe neighbourhood could hear the rumble and many were able to capture the dust cloud aftermath as the rocks settled at the base of the mountain .
The rockfall happened in the same area where large rockfall events took place in 2015 and 2021. In February 2026 a boulder fell in this same area, that rockfall happened just before dawn and sparks can be seen as the rocks tumbled down the face.

The rockfall on Monday could been triggered by recent change in temperatures paired with wet weather which can cause water to permeate into the cracks of the rock. Stawamus Chief Park officials warn rockfalls can occur at any time within the park and visitors are urged to use extreme caution.
Parks Canada Rockfall Safety:
Bare, freshly broken rock is a sign of active rockfall; these areas may extend well out from the rock walls and cliffs. In or around steep terrain, choose routes carefully, watch and listen for falling rock and avoid stopping for long breaks in potentially active or unprotected areas. Be particularly careful when it is raining and during periods of freeze-melt temperatures as these conditions loosen rock and increase rockfall. Choose campsites in protected areas, away from steep terrain.
About Stawamus Chief Park:
Stawamus Chief Park protects the 700-metre, awe-inspiring granite cliffs that stand at the southern entrance to Squamish on the scenic Sea to Sky Highway. The park provides rock-climbing opportunities of international significance.
Hiking trails to The Chief’s three summits offer rewarding views of Howe Sound, Squamish town, and the surrounding mountains. This park also offers camping opportunities.
The Stawamus Chief is one of the largest granite monoliths in the world and provides good nesting habitat for peregrine falcons. Please keep your distance from wildlife, and view with binoculars. Look out for posted closures of climbing routes during the critical nesting season.
