Observation: Chugach State Park

Location: South Fork Eagle River

Route & General Observations

15 cm of low density new snow was redistributed by consistent moderate S winds. This created very small (ss-r1-d1-I) wind slab at ridge top reactive to skiers where angle was over 32 degrees. The loading was active with skin tracks covered in 20 min. Only isolated small areas of cracking observed mid slope on >35 degree terrain where the wind transported snow exists and stiffened over the course of the day. SKi quality was good. We experienced no collapsing/whumphs although a poor structure with basil facets exists.
