Magical pond on the South end of Seavy Pass
Summit City Canyon from Mount Reba.
Seavy Pass is the high point in a wide bowl filled with beautiful ponds atop the ridge separating Bensen Lake from Kerrick Canyon along the combined TYT-PCT routes through the North Yosemite Backcountry. Above we are passing around the Southernmost pond before beginning the great descent to Bensen Lake.

Seasonal NOTES:
The Snowpack on the Sierra, storm activity, and temps during June are going to allow us to get a bead on when the Sierra Trails across the High Passes will start opening up, as well as the trails approaching them.

High Sierra Backpacker Weather

When the snows melt millions of mosquitoes rise from the saturated soils. It starts low down the mountain early in Spring and rises up the mountainside as Spring progresses. Be ready for the rising clouds of mosquitoes.

High Sierra MOSQUITOES

MARCH 2015 OBSERVATION REGARDING SPRING-EARLY SUMMER:
Everybody will open early, unless prohibited by use agreements. The issue driving behavior in June is going to be fires, not snowpack. This year is shaping up to have the hottest Wintertime temperatures pushing earliest opening of the Sierra trails and resorts with the least amount of snow and rain recorded since the Western settlement of California.

JUNE 2015 REPORTS:
A very warm unsettled month of May has brought continued unsettled Weather conditions into June. The overnight temps have been above freezing since late May, and the tropical remnants of Blanca appear to be scouring the remaining snow off the South Sierra quite quickly on June 10.
I expect a regular groove to be cut by hikers through what snow remains in the South Sierra mountain Passes along the JMT by the start of June.

Through-hiker permits into or across these areas are still available.

June 24 2015 REPORTS:
ENSO activity seems to be tormenting the central-East US with tropical moisture appearing as tornadoes and T-storms. The "gunsight" that points this energy our way is not seasonally adjusted to point at the Sierra, but it looks like the "clip" is full.

This means that as Fall cooling beings these tropical flows could be pointed our way, if ocean heating trends continue.

Or not. We could just as easily maintain drought conditions. I put the chances at tropical El Nino Fall rains at 50-50 from today's perspective.

2015 NO THAW TO SPEAK OF: IT IS OVER.

2016 THAW PROGRESSING ON "TRADITIONAL," if a bit-A MONTH-earlier than "AVERAGE" SIERRA THAW TIMELINE.

 

The real danger of June is found between the swollen banks of rivers and even normally small placid creeks, surging with the power of the Spring Thaw. (Not this year)

During heavy Spring Thaws one can hear the grinding of unseen great granite boulders as supercharged river flows easily roll them downstream. (Not this year)

Carefully assess all river crossings, have contingency plans for being knocked down and losing your pack, and turn around if the dangers are too great. (All Years)

Happy Trails!
