Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Wednesday - January 15, 2014 - 6:58am
bottom line

Dangerous avalanche conditions exist, and there is a Level 3 or CONSIDERABLE danger on many slopes in the Logan Area backcountry. Triggered large and destructive deep slab avalanches 2 to 4 feet deep and failing near the ground remain likely on steep previously drifted slopes, and there are areas with a HIGH or Level 4 danger at upper elevations on slopes facing northeast, east, and southeast. Wet avalanches involving moist fresh snow will become increasing more likely on sunny slopes as the day warms. Avoid travel on or beneath steep drifted slopes and obvious or historic avalanche paths. Careful snowpack evaluation, cautious route-finding, and conservative decision making will be essential for safe travel in the backcountry.




avalanche warning

AN AVALANCHE WARNING CONTINUES FOR THE WESTERN UINTAS AND LOGAN AREA MOUNTAINS. VERY DANGEROUS AVALANCHE CONDITIONS STILL EXIST. HUMAN TRIGGERED AVALANCHES ARE LIKELY ON STEEP UPPER ELEVATION SLOPES.     PEOPLE SHOULD AVOID ALL STEEP MOUNTAIN SLOPES. THIS WARNING DOES NOT INCLUDE SKI AREAS OR HIGHWAYS WHERE AVALANCHE CONTROL IS NORMALLY DONE.

current conditions

The Tony Grove Snotel at 8400' picked up 4.8" of water since January 8. It's currently 26 degrees and there is 54 inches of total snow on the ground, containing 87% of average water content for the date. It's 18 degrees at the 9700' Logan Peak weather station and the wind sensor still appears to be rimed or covered by ice. Dangerous avalanche conditions remain in the backcountry, especially at upper elevations on easterly facing slopes. The heavy new snow from the weekend accumulated and was drifted onto slopes with widespread very weak preexisting sugary or faceted snow....

recent activity

On Saturday, 1-11-2014, a Utah rider triggered and was caught, carried and fully buried by a very large hard slab avalanche north of the Idaho State Line. The 3 to 5 foot deep and perhaps 500' wide avalanche failed on weak snow near the ground. The severely injured rider had to be rope-hauled back up the steep slope in a heroic late night rescue effort by Cache, Franklin, and Bear Lake County SAR. More info... HERE

On Monday, 1-13-2014, a 19-year-old rider was caught and completely buried by a HUGE avalanche in the "Fairgrounds" on the east side of Logan Peak. Luckily, Dad spotted a red glove the rider was wearing, and he and his brother dug him out and resuscitated him. We visited the site yesterday, and will continue to update our report today. Preliminary report...... HERE AND, Here is our video look at the Fairgrounds from 1-14-2014. ******HERE

description

Very dangerous human triggered avalanches failing in old weak faceted snow or in the basal layers of the existing snow pack are still likely on steep drifted slopes at upper elevations today, with the most dangerous conditions on east facing slopes. You could trigger large and destructive avalanches remotely, from a distance, or worse, from below. Heavy snowfall and sustained strong west winds built a significant cohesive and heavy slab on very weak sugary or faceted snow. This unstable snow structure is now widespread across the Logan Zone.

description

Wet avalanches will be increasingly likely on sunny slopes as the day heats up. The fresh snow from the weekend could become troublesome as it warms, with natural wet sluffs becoming likely in steep terrain. It is possible that a smaller wet avalanches overrunning a slope with poor snow structure could create a larger deep or persistent slab avalanche. Avoid steep slopes with moist surface snow. Roller balls or surface sluffing are signs that the snow is warming up.

weather

It will be warm and sunny in the mountains today, with moderate west northwest wind, and 8500' high temperatures around 40 degrees. Expect fair and sunny weather in the mountains again tomorrow and for the next few days.
