Spatial Distribution:

Terrain
  Primary Concern Comments: Not reactive to ECT's on due south slopes. Still getting unstable results on the two shaded slopes i dug.
STABILITY TESTS
 Stability Test Results: ECTP 13's on north pits. ECTN's in south pits.
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
BOTTOM LINE
 Comments: Did not cover a whole lot of terrain. Like SVHS, found stability improving stability test scores on south slopes. Some decent highmark/sidehalls on south slopes also confirms this. Still poor structure on the two north pits with similar results with a 2100' elevation difference. Sled triggered slide looks like they found one of the few pockets of snow that had not avalanched in that basin.
