Summer of 2020 Backpacking Plans?
Yosemite-Hoover-Desolation
&
John Muir Trail Hikers:

 

It's Time to
Order This Year's Permits!

Reserved permits for the beginning of the Summer, for June of 2020 are now available from Yosemite, Hoover, and Desolation Wilderness Areas.

First shot at June reservations begins in December.

In other words, Yosemite, Desolation, and Hoover Wilderness Areas all offer advanced reservations about six months ahead of your desired hiking dates, so now it the time to get your preferred dates across the whole Summer hiking season.

This means now is the time to get your permit applications for popular hikes into the Man, and see if your best hiking windows are open.

For When?

Permit reservations for June open in December.

ON THE CALENDAR

Earliest
Start Date
Winter of 2015
Driest in History

Average
Start Date
Winter of 2016
An Average Year

Latest
Start Date
Winter of 2017

Wettest in History

These three years offer the potential range of Weather Conditions within which this year's PCTer,
"Start Date," the date you can reasonably expect to encounter fairly snow-free trails with post-deadly fording conditions will be
determined within.

This date, of course, depends upon your ability to navigate snow at high altitude, along with your ability to cross the various stages of the dangerous thaw waters draining off it.

You can get through before and after the period of high-flow runoff, but not during this phase.

How the conditions of the Winter to Spring
Transition we track this year measures-up to the classic trajectories of these three years cited above will inform potential PCT hikers about the snow/trail conditions along the High Sierra Crest they may reasonably expect to encounter during May, June, and July of this year measure-up against those of the Driest year in history against an Average Year, against the wettest Year in History...

This year of 2020 will fit somewhere between these historic parameters of the record Wettest and record Driest years that happened between
2015 and 2017.

As our seasonal start date for open access to trails along the High Sierra Crest will be adjusted according to the character and trajectory of this year's Winter to Spring Transition, we will watch it carefully.

What we're seeing today is one step in a transition between the last and the next in the series of vast, massive cells of persistant High Pressure air that have been covering the West Coast of California (if not the whole West Coast of North America) over the whole month of December.

Typical Year:

This 2017 High Sierra backpacking and backpacker's Calendar notes important hiking dates as our seasons progress to compare current and recent historical weather to determine the best gear for the conditions. We also track the expected against the actual dates our resupply locations and the trans Sierra highways that feed them open and close. We also include permit reservation timing reminder information for those who seek hard to get

 

 

NOTES:
December Tenth, 2015:
Intense tropical flows have so far been diverted around us by the same persistent ridge, the high pressure zone that's been gradually building, strengthening, and persisting over Winter in the Northwest and West Pac over the last fifteen years. Yup, that one. I am betting that each time this ridge breaks down from here on out we will have a good chance of North and Central California getting seriously hosed. The ridge persisting will continue the deluge that everyone from Portland Oregon, and points North, has been getting pounded with, so far this year.

The distribution of El Nino tropical moisture has been controlled by the balance of factors I discussed in the December Backpacker Alert.

Season's Greetings: Alex and all the members of Tahoe to Whitney hope you had a killer backpacking year, that you’ve seen amazing things and met incredible folks on the long trails between Lake Tahoe and Mount Whitney. Woo Hooo!

Now's the Time! November & December is the time to reserve permits in Desolation Wilderness or Yosemite National Park for next June. Half of each ‘s Wilderness Permits for these heavily used areas are available six months before the start date of the backpacking trip.

The Winter Backpacker

Very short days and long cold nights makes Winter hiking trips very different than Summer.

I’m hopeful the trails will be buried under yards of snow by December 2016…

If so, our goals, our speed, and our expectations have fully shifted into Winter Mode.

Our changing inner perspective ideally matches external environmental changes.

May your perspective always complement your environment, and visa-versa.

December

I am hoping my frostbite/heart is recovered enough to resume my annual Christmas-New Year Snow Camping Triangle at the end of 2016.

From Meyers to Round Lake to Showers Lake to Round Top Lake and back to Meyers is my traditional December 25 Christmas present to myself.

The terrain, the joy of navigation and route finding the snow-covered beauty of the High Sierra during Winter is a special experience well worth the efforts and hazards.

Happy Trails!
