I did the JMT in late July/early August 2006. That was a wet year but not nearly as wet as this year. All the high passes had snow but it wasn't really a big problem. Muir Pass was probably the worst. There was enough snow to do a standing glissade down part of the north side. Many folks were carrying axes and 'pons but they were not needed.

The real issue, as mentioned above, was the stream crossings. They were deep, cold and frequent. Some were a little dangerous. I went S-N and my feet were wet all day every day until Donohue Pass. There were just too many crossings to take my shoes off every time so I just lived with wet feet. On several mornings I had to put on wet shoes when I started for the day. The good news was, I never had to carry more than a quart of water at a time.

And yes, the mossies were out in force. I always has a litlle extra protein in my oatmeal
