Pine Creek to Royce

Pine -Honeymoon was a 3 during the middle of the day when hiking to GP
Lower GP was a 3 near water so we camped up on a ridge that kept it around a 1 with some breeze

Hiking into Upper GP the following morning was brutal even while moving and was very hot, about a 4

Lower Royce was a 0-1

Would love any info on Robinson/Crown/Snow lakes area

Does anyone have any information on the little Lakes valley area? I have plans for the end of august and want to know what to expect.
End of Aug will be quite different from now. It seems that the mosquitos are finally on the wane so I'd expect things to be fine by end of Aug, but keep an eye on reports closer to when you are going.
I was just there (main trail) from August 13th-17th Not too bad in the am or afternoon, level 3 most places in the evening, 4 in some bad spots near swampy areas and lake edges. We had permethrin treated clothes, including long sleeves and long pants, plus anti-mosquito nets, used picaridin on hands. no bites, but that was not for lack of effort on their part. The fish and dragon flies were gobbling them up, so hopefully you'll have an easier time. Above 11,000 feet on the Mono Pass Trail I didn't see any.

11-day trip Aug 12-22. Only dawn and dusk and/or in wet swampy areas. It was windy most of the time, so that helped. East of Kern River is quite dry and few mosquitoes; west of Kern River more mosquitoes and wetter conditions. Most mosquitoes were very small and not biting. I do not know if that means it is the start or end of the hatch. I used a head net a lot just because I do not like bugs in my face. Got about 5 bites.

Horseshoe Meadow (1-2), Cottonwood Lakes (1-2), Miter Basin (0-1), Crabtree Meadow on PCT (2), Wallace Lake (0-1), Upper Wrights Lake (0-1), Shepherd Pass trail down towards Tyndall Creek (0), Cross trail (0-1), "Casper aka Ghost" lake (2-3), Milestone Basin (2-3), trial down Kern River and HST up to PCT (1-2), Crabtree Lakes (0-1), out Trail Crest (0-1), Consultation Lake (0).

8/25 Twin Lakes to Barney Lake 0-1
I might have seen 2 mosquitos in the forest near the creek on the way up. Swam, fished, and laid around at Barney without seeing a single mosquito.

8/19 lodgepole: 1
8/20 buck creek: 1
8/21 tamarack lake: 2

table meadows lake: 3

two rangers said that tablelands/moose lake was more like a 5 last week, so perhaps they’re subsiding a bit.
