Baboon Lakes 6/26-27

Post by astrogerly » Sat Jun 27, 2020 7:44 pm

I’d rate Baboon Lakes as a 3, but borderline 4. We were blessed with an on and off stiff breeze that helped on Friday hiking in - skeeters got bad as we hit the Donkey/Baboon split. Didn’t have that breeze today hiking out and you could tell - skeeters from Baboon down well past Blue Lake... but tapering off as you got lower.

Grand Canyon of the Tuolomne and Ten Lakes Loop 6/26-6/28

Post by kdemtchouk » Mon Jun 29, 2020 1:04 pm

In much of the lower GC of the Tuolomne (up to ~5500 feet), I'd rate it a 2. Things got progressively worse climbing up to Glen Aulin and the top of Tuolomne Peak ridge (up to about a 3). My night at Ten Lakes was a bit windier and better, but man....the forested segment from the Ten Lakes/White Wolf intersection near Yosemite creek was terrible (strong 4). They would only stay off of me if I settled into a jog.

Beyers Lake area, Grouse Lakes RA, Tahoe NF, June 27-29

Post by wildhiker » Mon Jun 29, 2020 11:12 pm

I backpacked into Beyers Lakes and then dayhiked beyond it towards Baltimore Lake. Elevations 6000 to 8000 feet. Generally on south facing slopes. Wildflowers were peaking, but mosquitoes were not bad. Generally level 2 in sheltered areas. It was quite windy the whole time which kept the mosquitoes away in open areas. Never used any repellent, and only got a few bites.

Tamarack Flat to El Capitan 6/29-7/1

Post by ericmeyer315 » Thu Jul 02, 2020 10:50 am

The entire trail was a 1, except for a few stray skeeters while crossing Ribbon Meadow. This was despite Ribbon Creek and Tamarack Creek still flowing decently well.

Big McGee Lake 6/26-27

3 with no wind/calm conditions. Everyone brought muzzy nets, otherwise they'd have been quite annoyed.

Humphreys Basin/French Canyon 6/28-7/1

Post by windknot » Thu Jul 02, 2020 12:56 pm

Fierce wind on Sunday, 6/28 followed by a stiff breeze on 6/29 and 6/30 kept mosquitoes to a 1 in all locations except swampier ephemeral streams in Humphreys Basin, which were a 2. On Wednesday, 7/1, the breeze disappeared and the mosquitoes appeared as if they were conjured by a magician. I'd call it a 3 in the drier areas away from water, and a 4 anywhere close to water.
