Location: lower Manitoba

Route & General Observations

Hunting in the shrubs of Manitoba area, below 2100′, ran out of day light to get higher onto the actual ski slope. Snow depth was surprisingly good, whole ATV trail is skinnable/skiable. Grass in meadows almost fully buried.

Observer Comments

large high energy whumpfs between 1,700 ft and 2,100ft. Collapsing would shake snow of off alders 30ft away. Skinning in soft-slabby snow produced many small cracks.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

cloudy, near-freezing temps. Calm along the ATV trail and on lower slopes, but another skier said it was blowing hard near the "summit" of the Manitoba slope. I didn't notice any spindrift or other obvious signs of high wind to confirm.

Snow surface

3" of fresh light snow by the yurts over a thin icy base. 3-6+" of light snow above 1,600' over a crusty base mixed in the grass, surprisingly fun skiing in the meadows. Light snow hanging on every branch showing that there had been no recent wind at that elevation...on that side of the road. Looking across the road, the ridges of Fresno and Colorado looked scoured and the snowpack looked much thinner/spottier.


buried rain crust below ~1,800'. ankle/shin deep ski penetration while skinning around on flat ground. no pits or tests.
