Observation

Description of Snow, Weather, and Avalanche Conditions:

Observed natural avalaches on the east facing side of The Nipple, including a possible persistant slab (note the rock in the crown), and less than 24 hours old. Multiple snowpack tests in two different areas determined propagation was not likely in the recent storm snow or wind slab, and settlement cones were observed on trees, especially in warm areas. The temperature increased quite a bit throughout the day. STILL DEEP
