Coquihalla and Cayoosh Passes have about 50cm of snow on the ground, while treeline areas have around a metre. Alpine areas likely have much more that that but also highly variable depths. The main snowpack feature in the Whistler area is a rain crust buried early November and now down around 80cm at treeline. A weak layer of facets sitting on top of this curst recently gave very easy sudden collapse compression test results as well as moderate extended column test results that propagated across the entire column. Widespread whumpfing and cracking on this layer has also been reported. This weakness was found in the Duffey Lake area as well; however, at least at 1700m it was only 10cm off the ground and still moist. At upper treeline and alpine elevations it may be frozen and faceted and high enough off the ground to reduce the affects of ground cover at least on slopes with smooth ground cover (e.g. scree slopes, rock slabs, summer firn, grass, etc.).
