The Juicy, Techie Stuff:
BCA is releasing a brand new beacon this month: The Tracker 3. As you know BCA is a long time supporter of WAC and sponsors us at the high level. This new beacon is lighter and smaller than the Tracker 2 and includes their advanced electronics and industry leading features that BCA has always been known for. Check out their many safety product offerings.
We want to thank our donors this week who have responded to our new donor popup and who realize our volunteer efforts require $ to support our educational, website and corporate expenses. They are: Aric, Dennis, Dan (NJ), Dan (Hood River) and Charla. We thank all of you.
The tenth annual Eagle Cap Extreme (ECX) sled dog race will be starting a week from today, January 23 at 1pm. You can tune into the race communications HERE. Many of WAC's Board of Directors are intimately involved as volunteers. This is an exciting event with a 200, 100 and 62 mile race course. As of today there are over 20 mushers signed up and the race course travels all over the Wallowa Mountains with one checkpoint at Salt Creek Summit and one at Ollokot campground.

Sunday afternoon January 12, five snowmobilers were enjoying some fresh powder riding in Rock Creek Canyon deep in the Elkhorns about 11 miles SE of Anthony Lakes Mountain Resort. One rider was climbing a NE aspect, mid elevation slope when he triggered an avalanche mid way up the slope. The fracture propagated upslope catching, carrying and partially burying 3 of the party. Members of the party performed a self rescue and all made it out of the backcountry safely. WAC appreciates the candor in informing others of the hazards of avalanches and the lessons learned.

Instabilities within the newest snow from last weekend have settled out by now. The new/old snow interface of the last storm cycle remains of concern and slope cuts could provide useful info in conjunction with other means to determine slope safety. Slope cuts are never trusted to reliably reach the lower persistent snowpack weaknesses.
Activity reported this week were numerous D2 size slides. (Large enough to injure, bury or kill a person). These observed slides occurred at mid elevations BUT all around the compass. Could this be less wind direction dependent and more due to snow load? Think about it.
Snow and Avalanche Discussion:
Wallowa Mountain Weather Briefing:
It's called persistent for a reason. The mid pack crust/facet sandwich or graupel layer is showing reactivity and appears to be the weak layer in the recent snowmobile incident. Careful evaluation of a similar aspect and elevation test slope may give you data for a decision yay or nay. However, I am never trustful that stable test results warrant a go decision when spatial variability is at play. Poor snowpack structure trumps stable test results any day.
With continued worry and poor test results in the lower persistent weakness, most outback BC rippers had a high level of respect for and avoidance of avalanche terrain knowing a possible step down could lead to a very large, unmanageable and high consequence avalanche.
A catch-all icon for isolated wind slab, wet loose, wet slab and cornice fall. Normal caution means look out for everything else. Never let your guard down. Strong winds last weekend have built cornices off ridgelines and summits, along with wind slabs. Mid week heating and strengthening solar input has created pinwheels and roller balls, the first indicators that a wet slab release may not be far behind.
As they say, a picture is worth a thousand words. Remember WAC's weather station high atop Mt. Howard (8150') is responsible for this great data courtesy of JosephOregonWeather.com who kindly provides a path to the internet for us. The best part is having historical data shown in an easy read chart. Your donor dollars help to maintain this station as well as the one we own on top of Anthony Lakes Mountain Resort.
