Persistent slab structure through terrain

CB Avalanche Center 2015-16 Observations

Location: Kebler Pass Area
Date of Observation: 11/22/2015
Name: Evan Ross
Subject: Persistent slab structure through terrain
Aspect: North East, East, South East, North West
Elevation: 10,400-12,200

Weather: Not a lick of wind and warmer temps with stronger solar then the previous day.
Snowpack: Traveld through many different slopes in the upper OBJ drainage while simply probing for snowpack structure. Strong over weak structure would be very obvious in one location while 15ft to the side the layering would be much more uniform. This widely variable snowpack structure could be found on all slopes traveled, E, SE, NW, NE and elevations above. Collapsing was felt on many of these slopes, mostly while traveling over the slab margins. Though no natural or recent avalanche activity could be found in the area. So Persistent slab structure existed and could be found on the aspects traveled above, but the avalanche problem seemed to be very stubborn. Last weeks strong wind events largely lead to this variable snowpack structure. With the same slope being striped down to say, 40cm in one area and loaded with a hard slab over weaker facets say, 100cm deep only 15ft away from the shallower area.
