Quick report
• This was an impressive avalanche in Path 1163 with debris reaching 4500’ elevation which is about 850’ lineal feet from the rail (~85% distance to the rail). • Estimated the debris pile to be several hundred feet long and up to 20’ deep or more in some places. • This avalanche initiated about 2500’ above as a slab and then entrained a substantial amount of wet snow as it moved downhill, HS-N-R3-D3-O. • There were several chunks of broken trees in the debris, some reaching 8-10” in diameter. • 1” of new snow on top of a melt freeze crust which was sometimes supportable on skis, sometimes not. • Many sun-exposed slopes below 5000’ of disconnected patches of remaining snow with a lot of bare ground. • We could see some minor wind loading occurring above 6500’ due to SW winds. No signs of instability observed.
