HAZARD STATUS
Two Issues

1> Winter Storm & Temp Potential.

2> Full Winter Gear

The progression of the 2017 season's gear status change points began on September 15th, when Summer Gear was switched out for our Fall setup, three weeks earlier than this year.

This was followed up on November 3, 2017, when we brought out the
Winter Gear Selection
, which was two days later than this year, when Winter Gear was required on November 1.

Since that date different levels of Full Winter Gear have been Required, depending on the specific conditions.
We have reached the seasonal interface when temperatures can plunge to below zero.

GEAR

Careful assesment of weather and gear is now critical to trip planning.

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!
