Bee, it's where the trail turns slabby on the ascent, just above timberline. Not particularly challenging on the way up, but on the descent, even with no snow, it's easy to lose the trail if you're not paying attention. There's one spot in particular where you need to swing left as you head down, but it's not real evident due to the slabby granite. Bearing straight ahead or to the right will take you to the cliffy section and potential trouble in very short order. I've had to backtrack to the correct route a couple of times in this area when my mind was wandering or I was focused on a conversation.
Really, if you're following the trail, this is the only area of any danger between Trail and Outpost camps. Fingers crossed for a good outcome, but 3 days . . .
