how safe is it to spend the night up at the summit? I know there can be lightning storms. Would it be better/safer to camp at Lone Pine Lake or some other location? I think spending a night at the summit would be fun as long as its safe.
how safe depends on the weather, obviously. Storms at night are rare in summer. The more dangerous time is the afternoon usually. In '89 we walked up from guitar lake under a full moon following a late afternoon storm - turned out to be the best Whitney trip ever
On a busy day, don't expect to find room in the small open part of the shelter on the summit, nor is that a safe place to be during a storm.
view west just after sunrise, with the full moon still up high
