Signs of Unstable Snow

None reported

Observations

Dug a pit at approx. 4500ft N NE aspect. About 15cm of new medium density snow on top of a crust was reactive to 5-10 taps from the wrist. Did not seem to propagate in any clean manner. 15cm of fist density snow over crust, ~40cm of four finger density transitioning to 40-45cm of one finger density. No clear weak layer observed between the lower snow and 30 taps did not produce any clear reactivity. We turned around because new snow seemed prone to a slide in steep terrain, and mellower terrain had a crust that didn’t seem fun for skiing.
