The first slide is believed to have taken place Sunday night, sending a massive debris field down into the Cerise Creek drainage.
Both slides are on the opposite face of Mt. Joffre from the popular Joffre Lakes provincial park.
Members of B.C.’s backcountry touring and mountaineering community took to social media Thursday to express their dismay at the latest slide, with many lamenting the loss of the Central Couloir route.

Some worried that the region should be closed to visitors for safety reasons, while others theorized a third buttress on the mountain face would be next to come down.
Earlier this week, the Squamish-Lillooet Regional District said it was in consultations with the Ministry of Forests, Lands and Natural Resource Operations to see if a geotechnical engineer would be deployed to the area.
