Observation: Summit

Location: Tenderfoot

Route & General Observations

Morning laps on Tenderfoot to check out the snow conditions and snow stability after the weekend storm. We toured to 2600′ on a west, northwest aspect. There was about 7″ of heavier new snow by the highway. Snow totals higher ranged considerably depending on where the winds transported snow. We had a large collapse on west/northwest slope and a few shooting cracks. No recent avalanches and no red flags were observed until the collapse. The snow is obviously still touchy and not bonding well.

Large collapse at 2600' on a west/northwest aspect slope on a low 20 degree slope that was connected to higher 20 degree slopes. Shooting cracks around 6' long broke easily and was also observed as we rode down.
