Schuylkill Surface Hoar

CB Avalanche Center2016-17 Observations

Location: Paradise Divide Area
Date of Observation: 01/19/2017
Name: Arden Feldman and Jack Caprio
Subject: Schuylkill Surface Hoar
Aspect: North, North East, East, South East, South, South West, West
Elevation: 9000-11400

Avalanches: Skier triggered two D1 sluffs in the surface snow that travelled surprisingly far.
Weather: Increasing clouds throughout the day from clear to overcast with light snow beginning late in the afternoon. Generally calm winds with some light winds developing in the afternoon.
Snowpack: The surface hoar was present everywhere we travelled. Practically all aspects B/NTL including ridge tops. Did not travel ATL. On northerly aspects the SH was generally .5-2 cm in size, even in densely wooded areas, and in protected spots it was up to 3 cm in size with stunning crystals. On southerly aspects the SH was generally .5-1 cm in size and often sitting on a thin crust. At lower elevations in the valley, on flat and southerly aspects, the SH crystals were not as well formed but still present. Did not travel in densely wooded southerly aspects. With snow beginning at the end of the tour, the SH was almost certainly buried and preserved.
