Lillian/Lady/Standiford/Vandeberg/Chittenden Lakes, Ansel Ad

Postby AlmostThere » Sun Jun 26, 2016 3:01 pm

Just got back from watching a group of ladies run out of repellent in Ansel Adams Wilderness. About a 2 at Lady Lake, heavier at the lower, greener lakes. I got by with a light application of DEET in the morning and another in the late afternoon. They were noticeably worse today, the last of our three days out there.

Emigrant Wilderness 6/23-6/26

Postby kpeter » Sun Jun 26, 2016 5:27 pm

June 23-June 26 Southern Emigrant Wilderness

The mosquitoes get worse the higher in elevation you go--above 8000 especially. They can be especially bad from 7-9 am and 8-10 pm--as soon as the sun goes behind a ridge. They are also situationally bad near stagnant water at any elevation.

At Crabtree Trailhead and the lower part of Pine Valley all the way to Rosaco they were never more than a 2, in the evening at Rosaco they were a 3. Big Lake they were 2-3 at worse--I chose a dry camp with a great breeze, or they might have been worse. The worst mosquitoes of the trip were at Yellowhammer Camp--which is adjacent to swamp--at 8 in the morning. Definitely a 5. I can't imagine how Fred Leighton made a business taking people there. Five Acre Lake, Red Can Lake, Leighton, Karls, and the upper end of the Woods Lake trail were 4s during prime time and 2s in broad daylight. By today, however, the mosquitoes seemed to worsen on the way out. At 8 am coming through Groundhog meadow I had to put a bug bucket over my hat--easily a five.

I used Picaridin which seemed to work much as DEET does, except I am not convinced it lasts as long. I needed to reapply it more often.

Yosemite North Rim 6/24-6/26

Postby wildhiker » Mon Jun 27, 2016 9:16 pm

June 24-26 Yosemite North Rim
Hiked the semi-loop from Porcupine Flat to North Dome, then west to Yosemite Falls, then up Yosemite Creek back to the highway. Elevations 7000 to 8000 feet. All generally south-facing.
Mosquitos were a level 1 at our two camps, both on exposed open granite areas with light breezes, one on the saddle north of North Dome, the other on a bluff above Yosemite Creek just off the trail. But mosquitos were a definite level 3 in the forested areas, especially damp areas, requiring liberal DEET application. Got numerous bites getting water in midday at Royal Arch Creek - probably the worst spot on our hike.

I'm headed up to this area on 7/15 for a couple nights. Would anyone take a guess about whether the mosquito situation is likely to be better, worse or the same in 2.5 weeks?

I don't know how the situation will be in 2 weeks, but even in the level 4 areas, we were fine traveling with head nets, long sleeve shirts, and pants. I brought repellent but didn't use it. We got a few bites on our hands and legs when they were exposed while crossing streams. Good luck!

JMT (TM to Duck Pass Section) 6/19-6/23

Postby Snowtrout » Thu Jun 30, 2016 9:55 am

6/19-6/23, JMT from TM to Duck Pass. Bugs are out and ranged from a 1-4 depending on elevation. Wind blew from Donahue to Garnet keeping the biters away but had to eat dinner in the tent at Garnet when the wind died down. Gladys lake was the worst with biters during the day in the sun. Flying black ants were also all over Gladys. Reds Meadow campground was around a 2-3. At duck pass intersection, 1-2.

Mineral King 6/26-6/29

Postby mountaineer » Thu Jun 30, 2016 3:50 pm

Mineral King trailheads to 10,500' on Sawtooth Trail to Crystal Lakes and Monarch Lakes and Timber Gap: 0
Farewell Gap Trail: 0
Had reports from people coming off the Eagle Lake/Mosquito Lakes trail that sounded like a good solid 4-5 in the meadow areas.

Re:Dusy Basin 6/24-30

Postby Wandering Daisy » Thu Jun 30, 2016 6:22 pm

2 at South Lake trailhead 6/24, 3 6/30
0-1 6/24-6/28 at most locations, all elevations. Worse at the lower lakes (10,400). Mostly moderate winds kept mosquitoes down at the lower lakes. Very few to none above 11,200 feet.

6/29-30. Afternoon to 10PM rains on 6/28 got the mosquitoes going. 2-3 at lower Treasure Lake. 1-2 Bishop Lake to Long Lake.

At the end of the trip, I had to wear a head net or go inside the tent if I were not moving. Treasure Lakes seemed to have more wet terrain that favored mosquitoes. Upper Dusy Basin lakes had sufficient winds. Not the thick swarming phase yet, but it only takes a few minutes and they find you. Not a lot of biting, but a lot of in the face annoying.

Tuolumne Meadows 6/25-6/26

Postby SSSdave » Fri Jul 01, 2016 9:14 am

June 25/26 Tuolumne Meadows areas, very surprising to this person, only a 2. Have been in TM same time of summer several times in more distant past and squeets were far far more numerous. There is certainly enough stagnant water about. Wondering why there were not more out? Maybe 4-year drought has reduced snow mosquito numbers? Dragonflies and damselflies were however already out in numbers eating them. Generally mosquito numbers mid-summer the last 4 drought years have been relatively low and now after a more near normal precip year they may not be numerous because low numbers of over-wintering eggs.

I hiked about 10 miles over 2 days fully covered at times except face and hands while other times only wearing ls t-shirt. Put DEET on each morning. Just had a couple bites during day on t-shirt back and maybe a couple on hands after DEET had washed off while lounging around for lunch. Will be back at TM Saturday morning so will be interesting if there is any difference.
