NOTES:

Today we collected observations in Old Ski Bowl (OSB). It was snowing all day with low visibility, though there were a few brief clearing. Snowfall was sporadic with periods of light, moderate and heavy snowfall that seemed to change frequently. In a snow pit dug at 8,200 feet in OSB, we observed 16 inches of fresh snow over various crusts. Colum test showed planar fractures within the new snow 6 and 11 inches deep as well as at the new/old snow interface 16 inches deep (CT1 ⬇ 15 cm SC, CT19 ⬇ 30 cm, CT25 ⬇ 43 cm, ECTN ⬇ 43 cm). After hearing about recent avalanche activity on Gray Butte (GB) from other skiers, we headed over there for observations. For more information see recent avalanche observations.
