Recently I explained how an exceptionally snowy winter in California will affect summertime backpacking conditions throughout the Sierra Nevada, including in Yosemite, Sequoia-Kings Canyon, and Desolation Wilderness, and along the John Muir Trail, Pacific Crest Trail, Sierra High Route, and Kings Canyon High Basin Route.

For all the details, read the post. In short, expect:

Extensive lingering snowpack,

Saturated ground and flooded meadows;

Hazardous fords; and,

A delayed and prolonged mosquito season.

I think the information helped readers to set their expectations. But it actually instigated another round of questions, to the effect of:

What gear, supplies and skills do I need to safely manage these early-season conditions?

So, here we are.

Early-season tutorial

Rather than publishing one 2,500-word post that will challenge attention spans (mine included), instead I have broken it up into more digestible parts.

Applicability

The impetus for this post is California’s exceptional winter, on the heels of five years of drought and one average winter. Essentially, come June and July, many backpackers — notably, thru-hikers on the Pacific Crest Trail and John Muir Trail — will confront conditions that they have never before experienced. Since recent thru-hiking classes did not experience these conditions either, sound advice may be in short supply.

But the information in this tutorial is relevant every spring and throughout the Mountain West. This year the timing is just different, and it will overlap with more of the traditional backpacking season.

Usually early-season conditions are a May/June phenomenon, and by July — when traffic in the high country really picks up — everything is back to “normal.” Thru-hikers on the PCT and CDT usually experience early-season conditions in June in the High Sierra and San Juan’s, respectively, but this year it will be more intense.

Snowpack updates

Since my original post on February 21, the High Sierra’s snowpack has continued to grow, nearly on pace with the record-setting winter of 1982-83. For the latest, refer to these snowpack plots.

Elsewhere in the West, it’s also been a bountiful winter, with most regions experiencing snowfall that is well above-average. For non-California states, use SNOTEL data, which is produced by the Natural Resources Conservation Service, a division of the Department of Agriculture.
