Name: ADB

Subject: Cement Creek-Trail Run
Aspect: East
Elevation: BTL

Avalanches:

Drainage between Caves Trail Head and Walrod: E/NE Aspect Fresh: SS-N-R2-D2. Starting zone below the aspen groves. Some dirt shows in the scarp. Couldn’t see debris pile due to my location on the road. Did observe two drainages full of debris below the slide.

Close to the Cement Creek C.G. on the north side of road but no risk to the road and off of cliff bands: Appears to have occurred earlier in storm cycle as its’ filled in. SS-N-R0.5-D0.5 with sympathetic release with same size below.

Weather: Running short conditions.

Snowpack: about 13 inches of Sierra Cement on the deck in CB South. (24 hour storm total).
Southern aspects along the road: roller balls of different sizes and forms.

Aspect: East, South East
Elevation: NTL

Avalanches:

While touring up the Evans Basin ridge we remote triggered the steep, E-SE slope from 30′ away. It ran 150m wide and ran to the valley floor. Crown averaged 40cm’s deep with max depth of 65cms’s. It ran on small grained facets above a stout 2cm thick melt freeze crust. It was the 1/15 or 1/21 PWL. Midslope, it stepped down to the holiday? PWL for a 15m wide crown. SS-ASr-D2.5-O

Weather: Overcast day with calm winds and warm temps. Starting snowing S1 at 1330.

Snowpack: Today we toured up from the bottom of Elk Creek through Evans basin and over to RLG. We dug on a near treeline, east facing aspect with a hint of north in Elk Basin. HS 200cm, CT 12 SC on small grained facets down 65cm’s (1/21) The 1/15 PWL was down 80cm’s.

Avalanches:

Weather: Moderate to light snow starting just before sunset before strong, steady wind starts up around 3 a.m. New snowfall is 5″ with 0.53″ water in a warm, dense, wind driven snowfall. Snowpack back up to 53½”. Overnight low of 21F and current 26F with obscured cloud cover and very light to no snow. billy

Aspect: North East, East
Elevation: 8,800-10,300

Avalanches:

Weather: Overcast sky and calm to light wind. No blowing snow observed and not really too much for drifting from last night in this area. Mostly S-1 through the day. Clouds where hanging on the peaks, so not much for alpine observations.

Snowpack: 4″-5″ storm totals. No change in the avalanche problem as forecasted in this generally BTL type terrain.

Subject: Axtell 1st Bowl
Aspect: North
Elevation: 9,600-11,400

Avalanches:

No slabs, just sloughs. The far skier’s right entrance gully had sloughed through, presumably from previous skier traffic. Any undisturbed snow on the steepest portions of the slope was sloughing but not stepping down. Corner pocket had also run, but appeared to be natural and just in the new snow.

Weather: Overcast, mild temps (20s), light winds that were picking up toward the end of our tour ahead of the incoming storm system. Winds on the ridge were coming out of the SW, but down off the ridge winds were swirling, resulting in cross-loaded terrain features and some punchy wind crust in the more open terrain lower down.

Aspect: North East, South
Elevation: 9600′-10,400′

Avalanches:

1x SS-ASu-R1D1-O, NE Aspect BTL (2/11)
1x SS-ASu-R2D2-O NE Aspect BTL (2/11)
1x HS-N-R1D1-I S aspect BTL(several days old)

Weather: Sunny skies and little to no wind below tree line. Temps in the mid to upper 20s.

Snowpack: Two unique snowpack structures from South-North that will certainly cause problems if our next loading event verifies. Multiple crust facet combs on South which produced propagating results in an ECT and a collapse on approach to the 25 degree slope. Slabs above and in between these interfaces range from 4F-1F. HS ~130cm.  This test profile came from just above Kebler Pass road immediately above one of the ‘7 sisters’ slide paths. See picture.

On a NE aspect with HS ~160cm we investigated a skier-triggered avalanche from yesterday. The avalanche failed on 6-8 mm SH(see picture) that was likely buried on 1/21 with a crown depth ~45cm(see picture). This was an unsupported, open slope with many large boulders, rolls and small benches with slope angles ~38-40 deg at the top and ~35 deg mid track.  A test in an uncollapsed portion of the hangfire produced an ECTP14. The slide propagated into terrain as low as 30 deg. and ran 300-400 ft over the road to the creek. Debris was up to ~1m deep.
