The snowpack is generally shallow and poorly consolidated, significant variation exists within the forecasting area. The persistent slab may still be active in the Portal Creek area. This layer could be trigger from thin spots on the slope (trees, rocks, etc). Alpine wind slab is present on lee slopes. Springlike conditions below tree-line.
