In the mid 80's, I lived and worked for 3 seasons at Denali-days off, would go hiking and camping in the park. I remember one time being at Wonder Lake. It was a beautiful sunny day, and not a cloud in the sky -"the mountain" was out-it was heaven on earth, but also a living hell, with all those pesky skeeters. I swear, millions of them.😮. Wear the hat with the mosquito netting, and dress in long pants, , long sleeved shirts, etc. No skin exposure. Same thing at the Artic Circle at solstice. (summer😉!!!)
