Avalanche: Turnagain
Location: Turnagain Pass- Road obs
Drove through Turnagain Pass between 10am and 11pm and again around 12:30pm.Lots of large(D2) to very large (D3) avalanches from over the last week of storms. Corn Biscuit was the most recent in the last 24 hours.
Also worth mentioning there were some popular areas that did not slide over the last week and is still loaded, like Seattle Ridge from motorized lot to Repeat Offender, SW facing terrain of Tincan to Tincan Proper, much of the SW face of Sunburst.

Semi supportable melt freeze crust became unsupportable by early afternoon along road
Pete's North - crown on SW aspect (note how Lipps on lookers left has not avalanched)
Pete's North - crown wraps around to North facing terrain
Crowns and debris on North and West aspects of Corn Biscuit
Numerous crowns in SE gullies of Seattle Ridge on Southern side (from Center Ridge parking lot South)
Seattle Ridge farther South avalanche observed on SE aspect
Several small slabs seen at low elevation on Seattle Ridge across the street from Center Ridge lot
Other than a few smaller slabs, very little activity on Seattle Ridge from the motorized lot to Repeat Offender
Lynx Creek - East and North aspects both had fresh looking crowns
Tincan - North aspect - this happened sometime yesterday (3/18) between noon and 12:25pm
Sunburst SW face had one older crown from earlier in the storm cycle, otherwise most of this slope is still intact. Also note the debris in the foreground of Magnum's W face - this entire slope avalanche several days ago.
