Tracks on a slope do not mean it is safe.
Deep persistent slabs are a low-probability, high-consequence avalanche problem that are best managed by choosing to ride conservative terrain.
A weak layer near the base of the snowpack is a concern where a crust buried 10 to 20 cm is not supportive. Generally at higher elevations in the alpine and steep, rocky, open features at treeline is where triggering this layer is possible.
On Tuesday a few dry loose avalanches were reported out of steep terrain.
A large avalanche near Golden from Jan 29th reported in this MIN and pictured in this MIN, is a perfect example of the sporadic, deep persistent avalanche activity that continues to occur as recently as Saturday. Steep, rocky, treeline and alpine terrain where the crust is not supportive are likely trigger spots.
New snow has buried various layers of soft snow, wind-affected, and sun crusts. Further burying a crust now down 15 to 20 cm. This crust is generally supportive but tapers in the alpine and may be unsupportive to riders.
The midpack is generally faceted and the lower snowpack contains weak faceted grains, depth hoar, and crusts that continue to produce sporadic large avalanches.
