The Tantalus Range has had a bit of activity, will be interesting what the next weeks temperatures do!

At 2280 meters the temperature as of 03:00 was -7, winds were 10-20 KPH from the S.
At 1550 meters the temperature was -5.5, 77% relative humidity and the barometer is rising.
In the valley it is -3. The weather sensors are presently not up to date.

Large Debris Avalanche from the past:

Yungay, Peru (1970, May 31)
At 3:23 p.m., while many of the city’s 20,000 residents were listening to the closing moments of the World Cup soccer game, a huge earthquake shook the northern half of Peru. The city was soon in ruins - walls collapsed, houses crumpled, and the city plaza was split open. The survivors of this worst earthquake in Western Hemisphere history then heard a low rumble overhead. Millions of tons of icy snow break loose from the high slopes of Nevado de HuascarĂ¡n, tumbling down into lakes and reservoirs. The ice falls then cause lakes to overflow, sending a wave of mud, ice, debris, and rocks 10 miles down the valley at 3 miles per minute. The city and its 20,000 inhabitants, including some small villages, are buried beneath 100 million cubic yards of mud and rubble. Only 92 survive. This would be known as the worst avalanche in history. A Peruvian relief pilot, flying above the destruction, reported in disbelief, “Yungay no longer exists!

Owl Creek to Tenquille Lake Traverse, thanks to Micheal Gigliotti for these images and information.

Hi Wayne,
Numerous natural wet point release avalanches along the above traverse May 5 - 8.  Sizes estimated from 1 to 3 generally.  I added the three other pictures of a size 3.5 maybe 4 (uncertain of the trigger) that had cleared an avalanche path beyond its normal reach of the south side of Goat mountain.
Thanks for all the useful avalanche information collected and distributed this season Wayne.
Mike G.

If anyone sees any large releases in the next while or even in the summer please forward pictures and estimated times of the event. Working on the 2011-2012 winter cycle power point. Thanks Wayne
