I'll probably be up in the high country again in a few days. I can give you an update after that regarding bugs. I will say that every trip I've done this summer there have been mosquitoes, but the last one a week ago wasn't as bad and I assume it'll continue going that way.

As you know, pretty much all of that route is above treeline. It's been a weird season for weather and conditions can be unpredictable anyway. We're currently having stormy weather up in the mountains. Main thing is familiarizing yourself with the route, finding potential bail points, planning days with afternoon storms in mind, etc.

You may be able to get some cell reception up there and check the weather. I like the app with NOAA reports since you can pinpoint your location in the mountains. It's usually pretty reliable.
