That's a wrap for Avalanche Awareness Week! Thanks to everyone who attended one of our talks, clinics, classes, or parties.
Weather and Snow
We need more snow. What snow hasn't been packed out by riders is melting out in sunny terrain or turning into a sandbox in shaded terrain. Your greatest hazard today continues to be hitting rocks, downed trees, and stumps. You can still find pockets of cold, dry snow in sheltered, shaded terrain, but you'll have to work for it. An observer's pit profile from yesterday sums it up pretty well:
The 8500' Tony Grove Snotel reports 29°F and 17 inches of total snow on the ground. It's 30°F at the 8800' UAC Card Canyon weather station, with 20 inches of total snow.
The wind speed increased overnight, with current speeds near 30 mph and a gust of 60 mph. Currently, at 9700' at the CSI Logan Peak weather station, it's 21°F, and the wind is blowing from the west-northwest. At 9500' on the UAC Paris Peak it's 20°F, and winds are from the west-northwest, blowing 28 to 38 mph.
Expect cooler temperatures today with a high of 27°F at 8500 feet, gusty winds blowing from the west-northwest, and a few snowflakes here and there as a cold but mostly dry trough moves through the area. Cooler temperatures and a chance for snow(flakes) remain through Monday, with a return to high pressure by Tuesday. Our next chance for weather is Thursday, but uncertainty remains among the models about whether we'll get a ridge (strengthening inversion and no snow) or a trough (potential for mixing out of inversion and mountain snowfall). I know my vote.

We took advantage of yesterday's nice weather to install new instruments at the Card Canyon weather station. Thanks to Nate Z. and Devon for helping with transport and Travis M. and Chad B. for the installation.

Description
It is still early season, and the snowpack is shallow. Your biggest hazard is hitting barely buried rocks, downed trees, and stumps. Though triggering an avalanche is unlikely, here are a few things to keep in mind today:
  • Winds picked up overnight and will be gusty today - watch for shallow slabs of wind-drifted snow in exposed, upper-elevation terrain facing the east half of the compass and in and around terrain features like gullies, rock outcroppings. and ridges.
  • There is not a ton of snow, and what snow does get moved around will land on weak, sugary faceted snow.
  • Getting caught in an avalanche right now is especially dangerous because of the abundance of fixed obstacles like stumps, rocks, and downed trees.
  • Travel advice: Avoid fresh wind drifts and find good "loud" powder riding conditions in shaded, sheltered, low-angle terrain.
  • The locator rose shows where there is some shallow snow cover.
Additional Information
In this archived video, Trent explains the problem of weak, faceted snow development that occurs during high-pressure systems when shallow snow is subjected to cold temperatures this time of year. This is exactly the situation we find ourselves in the Logan Zone today. We'll have to monitor and map the widespread weak snow when storms inevitably start to roll in.

I found nice surface hoar crystals on Friday in lower Mill Hollow.
