AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 8 Within past week 1.5 7500-8500 Saw multiple old crowns several on W aspects along with a few on NE and E aspects
STABILITY TESTS
 Stability Test Results: ECTX after test I put my shovel behind the block and with a light pull the block propagated across the block and fractured on the T-Day crust which was not as stout as I have seen on othe aspects
SNOW STABILITY
 Snow Stability Rating for your observed area: Fair Confidence: LOW Trend: Improving
 Comments (aspects and elevations of instability, etc): Saw lots of roller balls in trees area at mid and lower elevations on W,NW slopes due to warming temps.
BOTTOM LINE
 Comments: Looks like this area had widespread avalanches on All Aspects and Upper to Mid elevations. These happened mid slopes and came out in pockets along with off ridge lines.
The snowpack looks to be slowly healing the crust were weakening and facets are starting to round out. Still I would be very hesitant about getting on anything steep or consequencel
