Location: Kebler Pass Area
Date of Observation: 02/25/2019
Name: Eric Murrow

Subject: Kebler Pass BTL Sunnies
Aspect: East, South East, South
Elevation: 9300′ to 11000′

Avalanches:

Nothing new observed.

Weather: Mild air temps with thin clouds passing. Winds were calm below treeline, no transport observed.

Snowpack: Poked a number of holes in S and SE slopes between 9500′ and 10,800′. HS ranged from 140cm to 175cm. All surfaces from SE-S-SW became moist today and were refreezing in the afternoon – surface crust ~1 cm thick. Two crusts of concern in the upper snowpack – the upper was generally thin ~1cm with on average 20cm F to 4f slab resting above. The lower crust was ~2.5cm thick with 40-65cm slab resting above. Facets below the second crust were up to 1.5mm in size. Upper crust produced ECTN results at all sites. Lower crust consistently produced ECTPH results below the crust, but locations with shallower HS failed above the crust.
Viewed numerous rider tracks on steep, drifted E facing features in the area and snowmobile high marks on steep, drifted SE BTL slope without any results. No collapsing while jumping on numerous small rolls.

Aspect: South West
Elevation: 9,560

Avalanches:

None observed.

Weather: Sky 2/8. Moderate Winds w stronger gusts. Significant wind transport observed at higher elevations from North Westerlies.

Snowpack: Not as deep on this aspect / elevation with a HS of 123cm. Surface was DF. Layers prevelant and reactive. Especially 2/2 down 40cm.
CTE 7 SP Q1 / ECTP 10 down 40 on FC/Cr combo. Bottom 20 CK’s was junky DH.

Subject: Morning Observations, Natural Avalanches
Aspect: North, North East, West, North West
Elevation: NTL-ATL

Avalanches:

Fresh natural avalanches within last 24hrs on W-NW-N-NE facing terrain near and above treeline from southerly winds over the last 24-36hrs. Large D2-2.5 persistent slabs were triggered by windloading, and small windslabs stepping down to deeper layers.

Wolverine- N-NE facing, ATL. D2.5 Failing from small windslab, then stepping down and propagating much wider. This avalanche looked to propagate the widest along WNW facing steep rocky terrain where the primarily wind direction would have stripped much of the snowpack hight this season. 

W-NW facing Gothic, ATL, D2.5. Failing similarly, propagating widely, failing on variety of weak layers from varied bed surface.

Peeler Basin North Bowl. Another very large natural avalanche. Probably D2.5 . The trouble here, is that there looks to be now cornice fall or windslab to trigger this deep avalanche. It just looks like one deep crown that ran naturally. More information is needed

A second hand report of a large natural avalanche that ran natural today on easterly terrain on Belview Mountain in the Gothic Valley. 

Many other natural avalanches were reported above treeline today. These were all generally small, other than the avalanches that previously failed and are noted above. 

Weather: Clearing skies, strong north winds above treeline, single-digit temperatures.
