Hello,

myself and 2 friends skied the Ursus trees in Rogers PAss today (friday
Nov.11)

Here are some observations:
elevation range traveled today: 1300m-2100m
Temperature: warm. 0 degrees at 1300m at 4pm
snowed 15cm throughout the day
wind: calm to light from South
snow depth: 60to100cm
Avalanches:
Size 1.5 slab avalanche was obsered. This slide failed on the Nov7th
surface hoar layer. 1950m. NE aspect. slope inclide: est. 27 degrees.
depth of slab: est. at 40-60cm. trigger: naural or skier triggered, not
sure. The slide crossed the exising uptract to Ursus Trees.

STS Couloir on Mt.Cheeops slid to middle of runout (300meters above valley
bottom)

Snowpack notables:
1) the Nov.7th surface hoar layer was observed down 50cm today. This layer
is ***HIGHLY*** reactive/unstable. stepping on snow-mushrooms/mini convex
rolls resulted in immediate failure of this layer with wide spread
propagation and shooing cracks. many whoomphs/setlements today. The nov7h
surface hoar crystals were observed up to size 7mm; that is relaively big
and means that this layer will take a long time to stabilize. The snow
above the Nov.7th has formed a soft slab. (4F+ resistance).

2) the middle of the snow pack is dense enough to carry a skier. Really
good traveling conditions for this time of year.

I would rate danger as considerable below treeline and high at treeline. We
did not observe the alpine.

Really good ski quality!!
