Drove from Glennallen to Fairbanks Sunday afternoon. 2-3" of fresh snow fell Nov. 25th at the road, more fell in the northern part of the range than the southern part. Slight breeze out of the south, but not enough to move the fresh light snow. Picture is looking north from the turnoff to the Arctic Man parking lot. Did a short tour in the central part of the Range. East facing slope, toured up to about 3,200 ft. The fresh snow had been blown during the storm. We found pockets up to 12" deep, and the fresh snow was not consolidated into wind slab. I would guess that higher elevations got considerably more than 2". Old windslab under the fresh powder was very reactive. We turned around because we triggered a whumph that traveled over 300 feet and lasted a couple seconds. Gullies were cross loaded and holding very deep pockets of snow - I would suspect these pockets could produce some sizable avalanches. Information is needed to asses how the windslab is bonding to layers below. This is the layer to track as the season progresses.

Rainbow Basin We were able to drive a Tacoma a little ways past Red Rocks Canyon. Toured into the basin via a route just east of the creek that drains the glacier. Made it onto the toe of the glacier before turning around due to flat light. The rain crust from the Oct 30 warm spell reaches the toe of the glacier (5,000 ft). This crust is highly variable in density and thickness across the terrain. In some places it is shiny and smooth, and other places it covers rough wind features that existed before the WX event. Cold snow was falling during the tour. 4-6 inches has been undisturbed by the wind at the toe of the glacier. At lower elevations, a north wind was strong enough to be stripping leeward slopes and depositing windslab on southern slopes. The windslabs were 1-6 inches deep in most places and growing. They were reactive on the rain crust. The Oct 30 rain crust provides a nice base to ski on, but will be a layer to watch for avy danger in the future. Due to its high variability across terrain features, beware of digging a single pit to evaluate this layer. Drove to the south end of Rainbow Ridge after getting out. Rainbow Basin was the only basin catching the WX coming from the North. There was a very abrupt break between clouds and snow and blue skies halfway down Rainbow Ridge.

Early Season in The Hoo Doos 18-22 degrees. Partly Cloudy. 5 MPH Wind from the South. Followed the Arctic Man course up to and behind "The Tit" 5800 ft elevation. Packed trail and rocks all the way until the top half of "The Tit". Top half West-Northwest facing bowl 1 1/2 ft deep. Snow depth doubles in the East-Southeast facing bowl. Small wind load on this aspect, no movement, no propagation of edge, consistent around entire edge of bowl. Direct south facing flats facing the Wrangells just below the drop in for Arctic Man had a two finger firm bed against the ground, a 1/2 inch above that was a small 1/4 inch ice crust a with a foot of four finger and then a foot of fist fluff. Layers on both sides of the ice crust adhered really well. Could not break off a smooth piece of the ice crust, snow or ground would come with it. Happy to see the strong ground adhesion and consistent 4 finger to cold smoke fluff on top around this 5000 foot elevation area. Lots more snow needed and lots more expected variables to come. Let's keep an eye on these layers as they build and pay close attention to our intercontinental snowpack. Sorry about the use of the Imperial System for measurements. My ability to eyeball Metric is just not there yet. *couldnt get videos to upload because of max file size exceeded. Only had a 2 minute video. Maybe we can up the file size to a decent iPhone size video. I'll try to get them on the Facebook page

Report of 20" on the ground near Miller Creek with snow falling and moderate to strong west-southwest wind transporting snow along highway MP 203-218. Heavy snow at times with 5-10" in the Deltas area accumulating by Saturday. Plan your New Year's adventures with avalanche eyeballs on.
