On shadier aspects, alpine surfaces are predominantly wind affected, with soft snow still to be found in at lower elevations.

These types of crystals (crust, hoar, facets) that develop on the surface as it sits exposed during prolonged periods of high pressure like this often become a problem once buried by the next snowfall.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":247,"length":12,"key":0},{"offset":470,"length":7,"key":1}],"data":{}},{"key":"3oj2e","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"31k3s","text":"A couple of layers of feathery surface hoar crystals exist in the upper snowpack.
