Seven Sisters Large Natural

Location: Kebler Pass Area
Date of Observation: 01/09/2017
Name: Zach Guy
Subject: Seven Sisters Large Natural
Aspect: South East, South, South West
Elevation: BTL

Avalanches: Checked out the crown above Kebler Road that ran last night..  It was ~3 to 3.5 ft deep, failed on the January 1st melt-freeze crust, and wrapped from SE to S to SW aspects below treeline.  Debris piles were at least 10 feet deep in the apron, and some of it reached the road.  Weak layer was pretty indiscernible above the crust, but it was nuking too hard to really look. SS-N-R4-D2.5-O.   Also spotted a couple D1 storm slabs on very steep, N aspects BTL.  Roof avalanche chaos in town.
Weather: S3 to S5, moist to wet snow. Moderate winds at ridgetop with a few stronger gusts and snow transport. Warm temps.
Snowpack: Spooky few signs of instability this morning. Traveled above some small, NE facing paths below treeline, and jumped around above them without producing any signs of instability other than very minor cracking and one small loose snow avalanche. About 1 foot of new, very dense snow.
