Hi! I would like to check if anybody who has recently climbed Middle or South Tetons could provide beta on snow conditions for the SW couloir approach to Middle Teton. Is there any snow in the couloir itself? We plan to climb this Saturday July 9 and are interested to find if we need to bring crampons, microspikes, or ice axes. Can trail runners be used or is it too early for this kind of shoes? Thanks so much!
