Recreational Observation

We travelled yesterday 2/22 from Timberline lodge to Zigzag glacier at 8,500ft to a point at 9,500ft SE overlooking White River glacier headwall / Steel Cliffs.

Feb. 22, 2018, 3 p.m. PST

Weather: Visibility was generally poor, except above 8,800ft, with light NW winds, light snow flurries and cold temps. No snow was being transported. Time: 15:00 Elev: 9,500ft Aspect: SW Incline: 30deg Wind: 330/10kt Sky: BKN with partial sun on slope Intermittent light snow flurries T-air: -16C T-surf: -12C T-20: -15C Observed some small facets (0.5mm) in top 20cm.

Snowpack: The surface consisted of low density snow at tree line with a ski penetration of 30cm progressively changing to a very smooth 4F to 1F supportable wind crust with a ski penetration of 5cm to 10cm above 8,000ft.The Zigzag glacier was almost perfectly smooth, featuring the same supportable wind crust. The snow depth above the rough rime ice crust was consistently 40cm to 60cm on the Zigzag. But where did all the surface low density snow get transported?

Area Description: Mt Hood South Climb route

Avalanches: No avalanches observed on route.
