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

Mostly clear with some low fog and occasional cloud cover. Cold for most of the day; around minus 10 to 15 degrees throughout the day. No new precip and very little wind.

Snow surface

Surface hoar on nearly all aspects and elevations. Wind affected snow at the top of Manitoba Peak and along the eastern ridge. Ski quality was good on both Manitoba and Colorado. Ski penetration 4-6” and boot pen about double that.

Snowpack

Lighter snow in the top 40 cm (15-20 inches) that transitioned to a denser snowpack, detectable with probe poles in both locations. No formal test pits dug. Quick hand pits didn’t identify any concerns for us with these upper layers.
