The Provo area mountains have widely variable snow and avalanche conditions. The American Fork area and the Wasatch Back had some of the weakest and thinnest snow of northern Utah up until a couple weeks ago and seem very different than other areas. Along the upper reaches of the Cascade ridgeline and Timpanogos, natural avalanches have run and repeated over and over on weak faceted snow from early season and/or early December (see photo example - below from two weeks ago). This localized structure has been subjected to significant wind loading and over 1" of snow water equivalent over the last couple of days and avalanches may step into this older and deeper layering. Extra caution is recommended in steep alpine terrain.
