Route & General Observations

Anchorage Nordic Ski Patrol / NSAA Manitoba Cabin Overnight Day 3: Followed the road from Manitoba Cabin past the standard uptrack and around to S facing slopes to see differences from W faces at higher elevations yesterday. Lower elevation crust was more stout than the day before (3/12) and *almost* unbreakable in some areas. Nice soft snow down to ~2200-2300 with increasing crust thickness and firmness on the descent. Breakable but skiable back to the road @ 1600′. Firm and speedy luge run with good runaway truck ramps at several corners on the road back to the cabin.

Snow surface

Smooth 4cm melt-freeze crust dissipating around 2300'-2500' depending on aspect.


Quick Test pit for an ECT at on a south aspect 24 degree slope at 2010'. HS = 169cm. While excavating a column to prepare for the ECT, the crust failed on isolation. This was consistent with what we felt underfoot in the nearby area while setting a skin track. ECTX... and the column was difficult to even pry loose. Rough layers in the top meter: K (MFC), F, 4F, 1F, P, K (NYE C?), 1F->4F, F (6cm facets). See photo. Ski Pen 4cm, Boot Pen 12cm
