Benjamin Firth,
Eventually all green bricks must come to an end. Plan on the hazard elevating with the increased winds and new snow starting Sunday afternoon and continuing into next week

Problems
Persistent Slabs
Keep an eye out for sporadic weak layers within the snowpack. These layers may be present in a form of buried surface hoar, facet interfaces, thin to fat areas and/or sun crust.
- Dig down to find and test weak layers before committing to a line.
- Be aware of thin areas that may propogate to deeper instabilites.
Aspects: All aspects.
