Avalanches: On south slope around 35 degrees, triggered a shallow wet slough, that traveled about 150 feet. Must have been slow moving as observed it on second lap. Slope position was an inflection point between concave and convex.
Weather: Obscured skies and mostly calm transitioning to S-1 with calm winds and slowly dropping temperatures.
Snowpack: 4 inches of new dense snow in the last 24 hours.

Avalanches: Approximately a dozen natural avalanches (L-N-D1-2) ran on the east side of Gothic within a half hour period as the skies cleared slightly around 1pm. With limited visibility and debris running over cliffs, it is hard to say for sure that that these were loose rather than storm slab avalanches. However, they seemed dry, came out of very steep terrain and didn’t trigger any additional slabs on the aprons below the cliffs.

Also saw a SS-N-R2D1.5 in a cross-loaded shallow gully near treeline that looked a day old
Weather: Temps slightly below freezing all day, snowing lightly (S-1) with a few periods of S1, mostly overcast skies with a few short periods of high thin clouds and strong solar radiation, light winds from the south, no blowing snow observed
Snowpack: 25cm of moist storm snow is settling into a slightly stiffer slab than yesterday over a 5cm thick layer of moist 3mm clustered melt forms, but test slopes and compression tests produced no results on a SW aspect near 10,000′ near Avery. A similar storm slab was much more reactive to hand shears on an east aspect ~9,500′ near the trailhead where it was on a wetter weak layer of similar grains.

Gothic

Avalanches: Several full depth (~12″ deep) wet loose avalanches came onto the shoulder of Hwy 135, D1 to D1.5, near and north of Almont. Not sure when these ran, but they looked fresh.
Weather: Temperature was above freezing at 10 p.m. Foggy, no current precip.
Snowpack:

Avalanches: Heard one large natural avalanche rumbling down the East a Face of Gothic around 2pm, but poor visibility all day limited observations. No other cracking or collapsing on short and very soggy tour.
Weather: Intense snowfall over last 24 hours with periods of 1″/ hour (S3), Air temp 3 deg C at 1300, consistently obscured skies and light to moderate northerly winds without significant snow transport in the valley bottom.
Snowpack: 1pm on flat terrain @ 9,600′ w/ HS 230cm and PF 50cm: 25cm of moist storm snow tops 20cm of wet snow over a thin, moist crust and an otherwise nearly homogenous and mostly dry snowpack. Compression tests produced hard PC results down 25cm on 3mm clustered melt forms and down 45cm on a thin layer of .5mm moist facets under the crust. Percolating water is not pooling on the crust here. Found Jan 19th surface hoar layer down 85cm, but CTN on this layer and ECTX 150cm deep. 30cm thick wet slabs failed easily under skies but showed minimal propagation on 35-40 degree small, well-supported test slopes.

Avalanches: No instabilities.
Weather: Mostly S1 precipitation with moderate and light winds. Winds didn’t transport ground snow.
Snowpack: Less than 2 inches/24 hours including today’s tour.
Hand pits on SW aspects:
1-2 inches of new snow on 2 inch wind slab. Below windslab, 3-5 inches of F hardness wet crystals on top of 2 inch 1F crust. Below were another 2 -4 inches of 4F snow.

Evidence and magnitude of this weeks winds? 2 to 6 inch snow globules littering some of the open slopes. Source: snow from aspens and spruce.

Avalanches:
Weather: Temps, 0C 10:45 9,000, 0C 11:30 9,400, -.5C 9,600ft 11:25, -.5C 10,000ft 12:30. Snow starting around 10:00am. S1 becoming S2 with periods of S5. PP/GP. Light southwest winds with Moderate Gusts
Snowpack: No much for signs to instability on slopes under 35 degrees. Traversed some southerly slopes at 9,800ft with and HS around 90-120cm and moist snow grains to the ground. Higher in the terrain the HS increased while the the moist snow only extended into the mid pack below the 1/19 interface. At 10,200ft, HS 182 ECTP 28 (Times 2) down 57cm on a 3cm P hard MFcr.

ENE slopes above 10,000ft had 5 to 10cm thick of moist snow at the 1/10 interface with 20cm of new snow on top. HS around 210. ECTX (times 3) down to the 1/19 interface, snow increasing in strength with depth.

Pushed a small loose wet avalanche down on a steep northeasterly aspect. On slopes over 35 degrees, a loose wet avalanche problem seemed like the main concern. Though uncertainty around unusual wet conditions leaves awareness to the potential of a larger wet slab at these elevations.

Avalanches:
Weather: A very wet, sticky dense snow overnight with 6″ new and 0.60″ of water. Stopped around 3 a.m. Still overcast but dry since then with 83″ on the ground. High yesterday a record for the 2nd day in a row at 48F. Steady wind yesterday but only light to none now.
