To supplement robertseeburger's post (did we cross paths?!?)...

Courtright to Hell For Sure Pass to Goddard Canyon to Evolution Basin and back, 6/19 - 6/21

Courtright to Hell For Sure Pass, 3-4.5 everywhere, except the pass itself (0 due to breeze)
Goddard Canyon: 3-4
Evolution Valley/Basin: 3-4

DEET kept them off of bare skin during the day. Lakes to the west of the LeConte divide were unbearable around dusk--I was trapped in my bivy between 8:00pm and 9:30pm while The Horde frenzied outside...

6/18 North Lake to Muriel Lake- afternoon heat, light breeze- 1, evening dusk - 2
6/19 Down Piute Canyon to PCT trail junction - breezy, hot, 1-2 down to about 9000 feet, then 0. None at campsite near SJ river
6/20 through Evolution Valley up McGee Creek to McGee lakes - gradually worse upward. OK as long as walking. Breezy. 1-2 (would have been 3 if no wind). Forested McGee Creek 3 when wind died down.
6/21 day hike McGee lakes - 0-1 move camp to upper McGee Lake - 2 at dusk. breezy
6/22 Sapphire Lake, day hike Lk 11634 - 1-0, very hot, dry, breezy. move and camp at Darwin Bench Lake 11540 - 0
6/23 Day hike upper lakes - 0 breezy, hot, an occasional mosquito in shady calm spots under large rocks - move to Darwin Bench Lake 11592- breezy 0-1
6/24 out via Lamarck Col. light breeze, 0 until Upper Lamarck Lake. 2-3 at Grassy Lake.

Saved by the grace of the wind gods! Only pesky a few times at dusk and dawn.

11,000+ elevations are very dry in spite of June snows. Grasses already dried out. 8,000 - elevations very hot and dry. Only a problem near water. Seemed worst at 9,000-10,000 elevations.

Tioga/Parker Pass/Donohue/Lyell 6/16 thru 6/23

Postby richapple » Sat Jun 27, 2015 5:07 pm

Semi loop trip from Tioga Pass Road over Parker Pass and out Lyell Canyon. June 16 thru 23, 2015.

Tuesday, June 16 - Mono Pass/Parker Pass Trailhead at Tioga - hike in day. Mosquitoes rating = 1.

Tuesday, Wednesday, June 16, 17 - Lakelets at about 11,200 ft east of Parker Pass (just outside of Yosemite). Mosquitoes rating = 1, perhaps would have been a "2" if not for a nice breeze at all times. This includes a day-hike to Parker Pass Lake and Helen Lake Wednesday, June 17.

Thursday, June 18 - over Koip Pass and camped at Alger Lakes. Mosquitoes rating = 1 hiking and camping.

Friday, June 19 - hike from Alger Lakes to camp just west of Waugh Lake (dry camp not close to Rush Creek). Approaching and over Gem Pass, Mosquitoes rating = up to 3 when breeze not helping, turning into a 4 the closer to Gem Lake and then up to beyond Waugh Lake. Solid 4.

Saturday, Sunday, June 20, 21 - Marie Lakes (just south of Donohue, not Seldon Pass area's Marie Lakes) - big lake with islands at 10,856 ft. Mosquitoes rating = 1 at the lake and around there. The hike up to the lakes Saturday had Mosquitoes at 3 up Rush Creek and along the JMT, and then up to 4 hiking past and up from the first lower Marie Lakes. Perhaps a 2 right when we got to that upper lake, but then we had plenty of breeze for the two days/nights, including some day-hiking. "Wind" would be a better term, but so much better than skeeters!

Monday, June 22 - camped at first plateau south of Donohue Pass, before dropping down to cross the lakelet at 10,200 ft with awesome view of (what's left of) the Lyell Glacier and those peaks of the Cathedral Range. The hike from Marie Lakes and up/over Donohue maybe getting up to a "3" for Mosquitoes when the breeze wasn't helping. And the same "3" for where we camped, with some breeze helping sometimes.

Tuesday, June 23 - hike out via Lyell Canyon, surprisingly down to a "2". We expected worse, and down in Tuolumne the little devils hadn't even really arrived. Yet.

Mosquitoes were 3 to 4 most places, though the breeze kept them from being worse.

High Sierra Trail, Crescent Meadows to Whitney Creek. Cross Country to PCT. JMT & Mount Whitney Main Trail to Whitney Portal - June 17-22 2015

I had treated my hat and hiking shorts with premethrin prior to our trip. The only place I pulled out the deet and head net was just after we crossed over Kawaeh Gap dropped down towards Big Arroyo. There was a 45 min time period, around 7 am that was unbearable. Just as quickly as they appeared, they were gone.

Horseshoe Meadow Campground (10,00ft) 6/29 - 0

No mosquitos seen (afternoon, evening and next morning). My original plan was to hike into the Cottonwood Lakes Basin for the golden trout opener (July 1st) but I had to abort my trip due to a very sore left hip/lower back so I can't report on the conditions up at the lakes. Bummer.

Bummer. I would have loved an update on that area. I expect it's pretty bad.
