Like many other areas of the Wasatch, the Ogden mountains has a generally poor thin snow structure with a checkerboard of hard and soft 'strong' snow over a PWL (persistent weak layer) of weak sugary faceted grains from early season. Avalanches running on this structure have been isolated and spotty, but enough to keep me from getting into steep polar terrain, particularly steep polar terrain that has recently been wind loaded. Despite the fact that the last reported avalanches on this layering were in the moutains east of Eden three days ago, remember that these weak layers are called persistent for a reason. Collapsing and cracking may or may not accompany other signs of unstable snow.
