There have been a few recent close calls in the north of the region near Golden. Very large human-triggered avalanches have been reported over the past few days. Conservative terrain selection remains critical.

Moderate

THURSDAY: sunny periods with lingering flurries, light south winds, -10C at 1500m. FRIDAY: cloudy with sunny breaks, light to moderate southwest winds, freezing level rising up to 1500m. SATURDAY: Flurries, light southwest winds, freezing level 1300m.

On Tuesday a skier triggered a size 2 wind slab near Panorama but was able to escape without being burried. On Monday, a size 2 wind slab was accidentally triggered by a skier in the backcountry around Golden.  On Saturday a size 3 sledder-triggered avalanche occurred in the Gorman Creek riding area near Golden. The early January interface is the suspected weak layer. Check-out the great Mountain Information Network report for details. Around the same time, a size 3.5 skier-triggered persistent slab avalanche occurred a few drainages to the south of Gorman Creek on a north-facing alpine slope. Nobody was injured in the event. Destructive persistent slabs are expected to remain reactive to human triggering for the forecast period.

30-60cm of snow has fallen in the last week, and resulting wind slabs continue to be sensitive to light inputs in upper elevation lee terrain. The persistent weak layer of surface hoar and facets buried in early January is now typically down 60-90 cm. The layer is slowly getting harder to human trigger in many areas, however, reports of whumpfing and recent large to very large avalanches around Golden indicate this layer is still very much a concern in the north of the region. In general, the lower snowpack below this layer is well settled and strong.
