Just there - no mosquitoes at all. If you camp at Outpost Camp, suggest camping to the left of the trail,toward the waterfall so that the 11:30pm - 4am "day" hikers are less likely to wake you as they shout with joy as their headlights shine on the Outpost Camp sign. At Trail Camp we headed to the "green zone" on the little map we were given, and found a spot on a ledge to the left, above the trail, above the tarn/pond. More secluded, sheltered. Definitely secure all food / smellies / trash in your bear can - we saw what was clearly the marmot party tent as we walked into the area. Trash explosion. Tent looked OK though.
