Mosquitoes were horrible at the upper Tyee Lakes and pretty bad at Piute. They were all above 9500 feet when I was there, and so lower Piute canyon and Goddard Canyon were completely free of them. Evolution Valley and Evolution Lake might have been bad, but it rained and they did not come out. I encountered them again coming up to and traveling through Dusy Basin, but I passed through quickly enough that they were not a problem for me. Again, people reported them being bad in the Long Lake area.dsotm wrote:No real problem with mosquitoes then? Coming from Arizona to do this loop in 2 weeks. Looks like it's going to be worth the trip!
In short, by the time you do this trip, they will probably be confined to the highest elevation band.
