the first 3 miles or so to hannegan pass were pretty hot and full of flys. The rest of the hike up to egg lake and copper mountain were beautiful weather and clear views! Small patches of snow on top above egg lake...enough to melt for drinking water if you dont want to go down to egg lake, but nothing to worry about. Also a few large puddles to filter water from. Mosquitos at night, but no flys till you get back down to hannegan pass and below. We actually had permission to camp above egg lake on the ridge at camp ""silestia???"" But when we arived one of the two parties camped there had obviously taken our spot without checking with the ranger station and getting permission to stay. We had to camp down at egg lake (still pretty nice spots) So, we missed out on the great ridge views for morning coffee and had to hike a few miles up to the lookout tower on copper mountain to enjoy our breakfast while seeing some spectacular views! All in all a wonderful overnight hike..except for the miserable flys!
