West flank of Murphy Peak, looking at North facing lines
We noticed strong upsloping winds from the west north west the last two days. Most leeward terrain in the top 100 to 200 feet is windloaded in the Rattlesnake. We triggered a sizeable windslab on the north facing terrain on Murphy peak today. We avoided South, Southeast terrain due to the obvious loading and cohesion of windslabs. We stomped a few times on this knife ridge and it broke over some cliffs. It was 1.5 feet +/- and propagated probably 40 to 50 feet however only 15 to 20 of that actually slid. Ran 200 feet however did not step down or propagate.
