Yosemite - Tuolumne Meadows to Waterwheel Falls June 8-11

Postby rgliebe » Sat Jun 18, 2016 7:09 pm

This is from a backpacking trip from Tuolumne Meadows to Waterwheel Falls down the Tuolumne River on June 8-11

Tuolumne Meadows 8600 ft - 1
Glen Aulin 8200 ft - 2
Waterwheel Falls 7000 feet - 2
Tioga Pass 10000 ft - 0

Mosquitoes were starting to hatch, but were only a minor problem. Wind helped keep them down.

Little Kern River 6/16-6/18

Postby hikerdude87 » Sun Jun 19, 2016 3:49 pm

Just spent a couple nights by the Little Kern River from Click's Creek TH. Most of the mosquitoes were in the meadows along the trail but down by the river didn't run into too many.

On the trail by meadow: 2
Else where on the trail: 1
Little Kern River: 0

Dinkey Lakes June 18-19

Postby AlmostThere » Sun Jun 19, 2016 9:18 pm

Spent the weekend clearing downed trees and chopping waterbars in Dinkey. Mosquitoes were starting to be interested in biting -- maybe a 1, in the morning and evening. During the day they were present in forested areas when the breeze died down. Not so much in the open sun. A dab of DEET here and there did the trick.

Glen Alpine Creek 6/18-6/19

Postby SSSdave » Mon Jun 20, 2016 9:13 am

Glen Alpine Creek drainage June 18 65.5k to 8.5k. Weather chilly, cloudy, very windy, no mosquitoes. June 19 light breezes, mosquitoes 1 most areas and 2 in the considerable areas of standing water. Suspect there are many more in the zone that were hunkered down due to several days of foul weather. Thus with this week's warm fair weather will bring many out with a lot of new squeets hatching.

Bear Lake in Emigrant Wilderness, 6/18-6/19

Postby JackH » Mon Jun 20, 2016 2:27 pm

June 18-19, 2016:
Camped near Bear Lake: Just a touch of wind: 2.

June 19, 2016 - Much warmer day without much wind. Mosquitoes on the trail between Camp Lake and the Crabtree trailhead were a bit of a bother in the middle of the day. Maybe 2+ or 3-

Tragedy Spring, Hwy 88, 6/19

Postby Nighthawk » Mon Jun 20, 2016 9:28 pm

Hiked down from Shot Rock Vista, about 7800 feet, light winds on generally open granite.
In most places, a 2. Shaded or still areas a 3. We encountered one sandy spot near a creek that was a 4 and got us several bites each in the 30 seconds it took to pick our gear back up and move it to a windier area.

Post Corral Creek - Fleming Lake 6/17 - 6/20

Postby michaelgrosse » Mon Jun 20, 2016 11:46 pm

Was in John Muir Wilderness Area off of Blackcap and Hell For Sure Pass Trail, June 17-June 20. The worse place we encountered mosquitos was at the Post Corral Creek Crossing. I would likely rate this a high 3 or even 4. We had Permethrin treated clothes on our way out, back to trailhead, after the creek crossing, and in order to get water, do a little fishing, and put on shoes, we had to put Deet on the exposed parts of our body to keep them at bay. The rest of the trail I would rate a 2 at worse, even the seasonal ponds, and marshy areas weren't as bad as Post Corral Creek Crossing. The strange thing was, we slept no more than 200 yards away from it on the first night and had no issues whatsoever. The second night we stayed at Fleming Lake and I don't think I saw on mosquito around our camp or in our area.

PCT Barker Pass to Donner Pass 6/21-6/22

Postby bwang » Thu Jun 23, 2016 9:06 am

Mostly 1 and low 2. A few spots (e.g. Barker Pass trailhead and some creek crossings) were maybe a very low 3. No Deet used but used mosquito proof wind jacket a few times. A few isolated sketchy snow patches remain (e.g under Granite Chief ski lift) but manageable with trail runners and hiking poles.

Bennettville, Shell and Fantail Lakes

Postby Jason » Sun Jun 26, 2016 8:41 am

Probably a 2. The morning hike in was fine, as was most of the day at the lakes where we had a light breeze. No repellent was used. On the hike out around 5:30 however, if you stopped in a spot with no breeze they'd swarm rather quickly. I was surprised by the lack of mosquitos at the lake....... not sure if it's early, late, or the breeze. Nice day though.
