Location: Kebler Pass Area
Date of Observation: 03/12/2017
Name: Evan Ross
Subject: Persistant Slab
Aspect: North
Elevation: 9,900-11,500

Weather: On and off very light snowfall through the mid day. A dusting at best. Light winds in this area. Overcast sky.
Snowpack: North bowl on Carbon had more wind effect then expected. Lots of wind board and scoured areas. The steeper north facing slopes were either wind textured or soft recycled type pow. No obvious sings to instability. Avoided one slope. When the snow was soft, ski pen was about 5-10cm.

At 10,800ft on a 35 degree slope, CTM SP and ECTN15. 35cm decomposing slab over old faceted snow.

At 11,400ft on a 36 degree slope. ECTP 14 and ECTP 22. Both down 45cm on well preserved 1mm NSF. F to 1F decomposing slab as seen in attached picture. Avoided the main steeper slope.
