Castle Pass - Peter Grubb Hut (PCT) 7/3 - 7/4

Post by thirdbestfriend » Tue Jul 04, 2017 4:21 pm

Most of the trails are still covered in snow, although Castle Pass itself is dry. With lots of runoff and few standing pools just yet, mosquito activity was a 1-2. No bites, we saw a few at the trail head off I-80 and sprayed our clothes to keep them away. Then, nothing the rest of the weekend.

I estimate the snow will be off the trails by mid-July, so you may have just a short window to hike there and enjoy the scenery without getting attacked.

Hi Thirdbestfriend,

Welcome to HST! Thanks for the update. :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.

Cottonwood Pass, Mitre Basin 7/1-7/4

Post by no2haven » Tue Jul 04, 2017 8:06 pm

Low level annoyance during the day: 1 in forests, 2 around lakes (Chicken Spring around noon) and creek crossings.

4 right at lake level (Soldier Lake) morning and evening, but quickly dropped to a 3 when you were 50 feet away from the water. Pretty bearable, actually. None seen in Mitre Basin during the day, and certainly not at Blue Sky (~40% ice covered still).

Lamarck col down to Grass Lake

Post by cgundersen » Wed Jul 05, 2017 9:03 am

As of June 30, we were getting sporadic mosquitoes just below Lamarck col (East side) and the bug count increased the lower we went. Grass Lake was a 5, but in the dry areas over toward North Lake campground, there were very few bugs (1). DEET kept 'em at bay.

Vernon Lake, July 1

Post by J ney » Wed Jul 05, 2017 11:44 am

Around a 1 or 2 on the slabs above the lake. 3 or 4 in the forested areas around the inlet and back towards the cascade down from Branigan.
Also saw 5 or 6 piles of recent bear scat.

Crossing Fall Creek was straightforward (about knee deep with a mild current) albeit with major repercussions for a slip. We did not see anyone else on the slab side of Vernon Lake.

Re: Florence trail, Goddard Canyon

Mosquitos were present and landing on us in meadows and wooded areas, probably a 1 or so, not truly bad. Swattable - about one per minute. I put on Ultrathon and wasn't bothered. Another hiker reported that Blaney Meadows area was "really bad" at around 9:30 am and we had more mosquitoes during the day than morning or evening, for some reason, not sure why. I wonder if sometimes people mistake flies/gnats for mosquitoes because they were worse than the mosquitoes.

Loch Leven Lakes 7/1-7/3

Post by Nighthawk » Thu Jul 06, 2017 12:05 am

A 2 for the most part. We camped on an open ridge and the wind kept them away except around dusk. During the trip out, a 3 in some wet and wooded areas.

Paiute Pass Trail 7/1-7/3

Post by jfr » Thu Jul 06, 2017 3:50 pm

As NightHawk said, the trail in the wooded area/aspens along the creek west of North Lake was about a 3 (at 9500 feet)

Paiute Lake was a 2 (at 11,000 feet)

Forsaken Lake below Mt Humphreys was a 1 (at 12,000 feet) - one mosquito landed on my hand after sunset
