More detailed information about the snowpack: 

Inconsistent snowpack tests across this slope today.  4 out of 9 block tests (CTs, ECTs, DTs) IDed sudden planer fractures in the deeply buried (58 cm down) crust complex containing very thin layers of weak grains.  These crusts were at or near snow surface on 20180124.  Top 50 cm of this snowpack is from 20180125-26 storm.   Not much cold snow hanging on here, but some.  Light E winds keeping the surface melt turned down a notch.  Snow on sunny aspects a little sloppy by 1330.
