Pioneer Basin 7/22-7/25

Mosquitoes were pretty much a 1 from the LLV trailhead to upper Pioneer Basin. I didn't use bug juice once and came back with only two bites, so there must have been a couple of stealth ninja mosquitoes doing the rounds.

Cottonwood Lakes-Miter Basin 7/22-7/29

Post by BigMan » Mon Jul 30, 2018 9:46 am

Horseshoe Meadows-South Fork Lakes-Long Lake-New Army Pass-Miter Basin-Lower Soldier Lake-Cottonwood Pass

0-1 the entire trip. And with very little wind. Even in the wet meadows of Upper Rock Creek. Total non-factor.

Minarets 07/26-07/30

Post by Carne_DelMuerto » Tue Jul 31, 2018 11:26 am

Beck Lakes Trail: 1
Beck Lakes: 1
Upper Iron Creek Drainage: 1
Upper Dike Creek Drainage: 1
Above Ediza Lake, Iceberg Lake, Cecille Lake, Minaret Lake: 1

Basically no issue with mosquitos the entire trip. Only the swampiest area had enough to be annoying. I didn't use DEET the entire trip.

Thanks Beta, and welcome to HST! :thumbsup:

I don't give out specific route information, my belief is that it takes away from the whole adventure spirit of a trip, if you need every inch planned out, you'll have to get that from someone else.

Ansel Adams Lyell Canyon 7/29 - 8/2

Post by Barton2018 » Mon Aug 06, 2018 7:41 pm

Mono Pass to Alger Lakes 1-2
Alger Lakes to Clark Lakes 2
Clark Lakes to ~1.5 miles N of Donahue Pass 1
Lyell Canyon 2

Hiked Mono Pass to TM 7.29 to 8.2. Was glad I had repellant, but could have coped without it. Only mosquitos I noticed were during water breaks on trail in forested areas between Gem Lake and Clark Lakes and portions of Lyell Canyon (lower). Also, our last camp in Lyell Canyon had some level 2 (light) in the afternoon/evening when we arrived. Never saw enough skeeters to deter swimming.

John Muir Wilderness, Kings Canyon NP Aug 9 - 14

Post by Bedbug » Sun Aug 19, 2018 12:22 pm

South Lake / Bishop Pass / Dusy Basin / Palisades Basin

Level 1 at all locations (except in the campground near South Lake), very few flying pests. Some mosquitoes came out right before sunset, but left with the sun. Did not need much repellant.
