This is a cross-section of 16″ of new snow sitting on the old snow
at the crown of one of the natural avalanches in Main Bowl above
Seattle Creek (see photo of slides in photo gallery).
The arrow points to where the avalanche failed which was at the
interface of the new and old snow. More specifically around .5cm
below the old snow surface in 1mm small grained near surface
facets with 2mm surface hoar intermixed.
Also, you can see where the density increases in the new snow with
a darker color in roughly the middle third. This can make the
riding feel ‘punchy’ and inverted.
