Subject: Owen/Purple Cirque
Aspect: North, North East, East, South East, South
Elevation: 11,700-12,300

Avalanches: Multiple old wet loose avalanches on Purples south face. One that seemed to trigger small slab R1 D1 but underneath a rock outcrop.
Weather: Clear, warm morning, light local winds from SW.
Snowpack: Did a fair amount of probing on a ~12,300 ft contour line on E-NE-N facing slopes HS between 270cm and probe eating. Jan. 29 interface seemed to be down 60-90cm depending on place. Dug a pit on N facing slope at 12,300 near Jenga, HS 355cm , only tested top 110cm’s, no results with CT and ECT tests. Jan. 29 slab was pencil hard resting on 1F hard slab .5mm facets at 60cm. Snow surface primarily stiff wind board and sastrugi. Textured sas skied best. We did trigger one long shooting crack ~50ft on Purples south face, enroute to S Couli, snow surface was still knife hard, boot pen was 1-3 cm. Not sure how deep crack went into pack, we quickly retreated.
