Hi All!

So I'm planning my second trip out to Yosemite this summer and am hoping to head up Mount Lyell to see the glacier (while it's there...). I'm planning on heading up the John Muir Trail and spending a night before the summit on day two. The trip is planned for mid-July. What kind of temperatures are typical up there around that time?

Cool or warm. I use a 32 deg bag that time of year (well 8-10 months of the year regardless).
