Vantage Point: From base of face

Caption: A massive fracture line extending across the west face of Wedge Mountain.

PhotoDescr: The Wedge area has seen some fairly recent large slab avalanches, some like this one having crown lines up to about 60-80 centimetres. Very unusual for this late a date. In fact, this avalanche and its debris seemed to have struck after spring isothermic slides had begun (you could see the intial runnels of these above the crown lines). My non-educated speculation is that the rains of the recent month (the most sun-obscured June on record for BC) soaked the snowpack until it reacted against a weak storm layer. But Mitch Sulkers contends that this slide is actually a recent/late season storm cycle's slab reacting against the winter's isothermic snows. This would likely mean that the latest storm deposited a very large amount of snow. I am now wishing we had spent more time analyzing the slide when we were there. In any event, a real eye-opener.
