Observation: Turnagain

Location: Magnum

Route & General Observations

Skied steep south and west aspects of Basketball and Magnum. New surface snow was denser in the alpine than in treeline. Snow was hard and hollow in some ridgeline areas, producing cracks when walking. Snow on steep southerly and west aspects was also denser than at treeline, but still powdery enough and thoroughly enjoyable – said steep south & west facing snow did not produce cracks or give other causes for concern. Ski penetration was about 10cm. We produced dry sloughs that ran most of the length of the slope on our decent of Basketball.
