Tilly Jane (3,800') to Tie-In-Rock (8,500')

Jan. 12, 2017, noon PST

Weather: Calm winds, Clear, Temps 10F-20F

Snowpack: Below Treeline (4000-6000'): dry, loose powder, ski penetration avg 15cm. Evidence of past east wind transport near ridges, subsequently overlaid by most recent snowfall. Widespread SH. No signs of instability. Treeline (6000-7000ft): variably supportable wind crust / wind slabs of 1F hardness poorly bonded to underlying F hardness snow. Recent hard slab formation on NE-E aspects due to west winds. Ski penetration 1-3cm. Alpine (above 7000ft): supportable wind crust / wind slab of 1F/P hardness overlying F hardness dry snow. Ski penetration 0-1cm. Generally smooth, carvable surface (sastrugis near ridges). Slabs likely hard to trigger but potentially consequencial.

Area Description: Mt Hood North Side

Avalanches: Eliot Glacier 8500': crown/debris observed at/above middle bench. D1 hard slab likely triggered by icefall. Eliot Glacier 7800': crown/debris observed on west moraine (NE aspect, windloaded, D1). See attached picture Eliot Gl
