WOW. If anyone read my trip report from Thursday, and other peoples, they would see that microspikes/Yaktraks and hiking poles are not the way to go up or down the chute....you need an ice axe and crampons to ascend and axe to descend safely. My buddy and I saw lots of people really struggling to ascend with 'spikes and poles...no idea how they fared on the way down..luckily no one got hurt that day (I don't think!?).
Stay safe out there folks!!
