Avalanche: Turnagain
Location: Turnagain Pass Road observation
Drove through Turnagain Pass at 12pm and again at 1pm to take advantage of some decent visibility early afternoon and look for any natural activity. Could see much of the popular terrain and most of the Natural avalanche activity was on Southern side of Turnagain.
