Sphinx Mountain

Date
Activity
Ice Climbing

There was no snow until slightly above the saddle between the Helmet and the Sphinx where we found a patchy distribution of approximately 2-12 inches of wind blown snow (above 9,200ft). This is a photo of the conditions on the North face from around 9,700ft (As of 10/15/20). Ice conditions were not impressive. These observations were made in very low visibility. With the new snow and forecasted snow, use caution when heading out to enjoy some early season ice climbing near the Sphinx.

GNFAC Avalanche Forecast for Mon Oct 19, 2020

Snowpack and Avalanche Discussion

<p>Avalanche season is here. While most slopes still have rocks and grass poking through a shallow coat of fresh snow, especially at lower elevations, there are some higher elevation slopes with dense, wind drifted snow that hold the potential to avalanche. Right now the hazard is still localized. Slopes where new snow is drifted deeper may provide enough coverage to eke out a few turns, but are also the most likely place to trigger an avalanche.&nbsp;</p>

<p>Avalanches don’t discriminate - they don’t care if you’re trying to get a head start on the ski season, looking for early season ice to climb, or out scouting for game before the start of rifle season. Either choose to avoid steep, snow covered slopes entirely or prepare for avalanches like you would in the middle of winter.&nbsp;</p>

<p>Bring a partner, carry rescue gear (beacon, shovel and probe) and travel one at a time in avalanche terrain. Cracking and collapsing of the snow is bulls-eye information that the snow is unstable. Avalanches will likely be small, but the many exposed rocks and hazards make small slides season ending at best and deadly at worst.&nbsp;</p>

<p>We are preparing for winter, scheduling avalanche classes, and setting up weather stations. If you have avalanche, snowpack or weather observations to share.

Doug will do an online Forecaster Chat about early season snowpack and avalanche accidents on Thursday, November 5 at 6 p.m. It is hosted by Uphill Pursuits and details will be posted soon.

Elephanthead Mountain, Absaroka Range

Date

Hi guys, I know that the Absarokas are out of your observation range, but since the storm activity and temperatures seem to be sort of consistent throughout the greater area I thought I’d submit some general observations from Elephanthead yesterday anyway. I ran in and climbed the peak via the North face coming direct from Mission Creek and observations are from the N/NE face at about 2 pm. Rain turned to snow around 8,000’ and the snow from 8K to about 8700’ was pretty wet and warm, pinwheeling down easily and on its own and only about 3-4” deep. Above 8700’ to about 9,000’ the snow dries out a little but remains very thick and sticky and there are areas where it has fallen on top of snow from previous storms. Above 9,000’ of course is boilerplate ice .5” to 2” thick covering every surface except rock outcroppings that is either scoured by the wind or covered with thick wind slabby snow (mostly cross loaded). I just dug a couple of hand pits where there was enough snow and what I found was at the base there is a thick, hard crust of old snow that I couldn’t scratch through with my hands. Layered on top of that is some softer snow that is pretty dense and seemed to be fairly well bonded to the crust underneath for now. On top of that is a wind crust 2-6” deep where I observed sun and wind affect on the surface. The snowfields have 6”- 4’ of new snow loaded onto the preexisting crust of old snow. There is enough snow up there to ski if you’re willing to battle your way in there and it is encouraging to see the snow coming in warm, dense, and sticky this year. The old snow has created a bed surface that is a cause for concern as more snow falls, the wind continues to blow, and temperatures drop. Also the areas where the wind has cross loaded into thick slabs is a bit worrisome. Those are easy to see in the photos I attached. Cheers!
