A friend and I spent three days ski touring on Kalhabuk Mountain in the Brooks Range (Wiseman, AK).  Since there’s no Brooks Range observation page and I’ve received a number of questions about the conditions from EARAC folks, I figured I’d post our report here.  The skiing was phenomenal: great spring corn on eastern aspects and 6-12 inches of re-crystallized powder on northern aspects. …

General Observations

Freezing temperatures at night seem to make stable snow snow conditions in the morning. Warm temperature and sun exposure create a soft top layer loosening bonds between snow layers in the afternoon creating unstable conditions. I have a photo, but it will not attach.

Witnessed a rider climb I steep south facing hill around 3pm Sunday. Triggered a decently large avy in a terrain trap. Watched the ride come down around the avy and ride up to see if his riding partner was caught. Thank goodness he wasn’t. Rider that set the avy off did not have a beacon prob or…

We skied a bit up Trims Cr and bushwhacked to the ridge. We camped and skied out Michael Cr on Sunday. As soon as the sun hit the snow on Saturday morning it turned into an isothermal mess and started creating wet slabs with shooting cracks. If the weather stays warm like this, wet slabs will definitely be…

Skiied in about 2.5 miles from the road to the Castner Glacier. Dug a pit on an east aspect, 21 degree slope. Top 15cm was a melt/freeze layer, with a pretty solid sun crust. Next 15cm down was a 1-finger hardness slab, then an ice crust, with another 25cm of 1-finger density slab below that. The…

We found a large natural avalanche that looked to be caused by cornice fall (we didn't witness it occur). West aspect, starting at a ridge just below 5,000'. Located south of the Denali Highway about 15 miles east of Cantwell.The ski approach from the DH was varied- by 9am the snow below brushline was unsupportable, but above…

Checked out conditions near the College Glacier today. It was warm! Didn't check the thermometer, but certainly above freezing. Noted some newer point releases on steep solar aspects.Up at 5500ft on the glacier, snow was deep, 245cm. However, the whole area seems to have a variable 3-5cm thick, melt freeze crust with seemingly bottomless facets…

Castner glacier: We skied out along castner glacier. Trail is well traveled to the first ice cave but deep snow- definitely helpful to have skis or snow shoes. We camped between the first and the second ice cave. Snow was knee to waist deep and soft so it was helpful to wear skis when around camp.…

Very sunny and warm weekend on Castner Glacier, almost no wind. We went 3 miles in, close to a second ice cave and ice ledge to practice prusiking. Upper snow layer in some areas up to knee deep and very dry. Almost impossible to compress to build tent base. On hills often windblown with very…

Skied up Ann Cr and up onto the ridge on the S side of the drainage. Dug a simple pit on the N aspect (19 deg) before the left turn and steep section in the canyon. Snow was highly localized, with wind crusts and melt freeze crusts. Right below the ridgetop 3/4 of a mile further,…

Reached the summit of White Princess with clear skies and warm weather! The snow was far to crusty to ski from the summit, but with a few more weeks of warm weather a ski descent of the south face from the summit should be possible. We skied the south west face, below ~8000ft there was several inches of loose powder on a…

General Observations

Skinned in and camped at the toe of the Castner glacier.  Snow conditions and depths varied depending on aspect/location.  Generally, there was about 4 inches of powder covering a harder layer of wind blown slab.  The slab was easily breakable making travel without skis/snowshoes challenging.  The base was mostly faceted snow.  Temps ranged from 22F in the sun to -5F at night.  We…

Beautiful blue bird weather all weekend! Super sunny and warm, no wind. It was pretty wind slabby in most areas and there was a lot of hoarfrost underneath the wind crust layers. We saw a little natural avalanche on a slope that was ~35-40 degrees and South facing. We just stuck to the mellow areas and didn't try…

Beautiful day at the Canwell Glacier. Skied to the toe of the glacier via miller creek - about 2 miles in and observed variable snow depths depending on aspect. There was 5-10cm snow above a thin melt-freeze crust and mostly facets to the ground below that. We heard some whoomph noises in the flats. We did not do a…

Skid down NW aspect. Observations: Plenty of old avalanches in Michael's Creek, non appeared to be recent as the debris was covered in drifted snow with no recent wind. Snow up headwall was 4" to 6" powder over a hard base, …

2/24/19: Skinned up Trims Creek (inspired by last week’s group!), followed ridge west of Item Peak headwall to about 6500ft, skied mostly W/SW aspects from ridge back down to Trims drainage. Very sunny day, some wind in the creek but calm further in.  Very variable snow conditions overall. Snow surface has been shaped by wind…

Skied up Trims Creek, generally easy going with deep soft snow in the creek. There were two spots where the creek had open water that forced us to bushwhack around on steep alder covered slopes. Hopefully these will get filled in later in the winter and it will much easier.

We continued up the creek and climbed on to the east face of Lion’s Head. Above 3500 feet the snow conditions…

The snow was covered in a hard crust, and heavily wind scoured on southern aspects, in some spots exposing the ground. Northern aspects looked softer but still…

Excellent conditions on Rainbow Ridge. Fresh snow has been blown around into unconsolidated drifts that range from 3 in. to 3 ft. deep. In general, the new snow seems to have bonded very well to the old crust in this area. Windslabs are definitely a concern and are highly variable in terms of their density,…
