When, Where, & How We Humans Spread Globally sticky icon

When, Where, & How We Spread Globally

A handful of recent discoveries have shattered anthropologists' picture of where humans came from, and when,
Business Insider, January 5, 2020

MAIN POINTS

New Picture Emerging
A New Puzzle, Really...
"A 2017 finding in Morocco threw into question the idea that modern humans originated in East Africa. Those bones were significantly older than any others ever found."

Trickle?
"The initial dispersals out of Africa prior to 60,000 years ago were likely by small groups of foragers, and at least some of these early dispersals left low-level genetic traces in modern human populations."

Flood?
"A later, major 'Out of Africa' event most likely occurred around 60,000 years ago or thereafter."

Planning and Preparing for a late Winter-Early Spring snow backpacking trip in the High Sierras

Snow?

Considerations
on
Preparing and Planning for a Snow Backpacking Trip in the Sierras

(Well, although it is Fall, the principals explored below apply to Fall as well as Spring....)

Video Prep Guide
I have constructed this four-part video guide to preparing for a High Sierra backpacking trip. Though it is designed for a Winter-first day of Spring trip, the basic principals discussed are applicable to backpacking during any season.

NOTE: Site Video Links Broken. See these Backpacking Food Prep videos on YouTube.

Factors of Success or Failure
Part one covers the range of factors you may encounter and must prepare for when backpacking in High Sierra snow. These considerations will control your preparations. These considerations are interrelated, and your measurement of each will affect the others.

High Sierra Spring Snow Backpacking II: Round Top to Round Lake Coyote, June 8, 2010

Spring Backpacking

Video

Tahoe to Whitney, YouTube.

 

Next Video: Spring Snow Backpacking trip, Round Lake to Showers Lake, June 6, 2010

South Tahoe Basin & Roundtop Review
These are two of the many videos I took of a grand snow shoe loop from Meyers to Showers Lake, from Showers Lake out of the Lake Tahoe Basin to Round Top Lake, then back into the Basin via Round Lake to exit the snow at Meyers, where we first started.

Spring Fun
This was a delightful Spring Snow backpacking trip, full of fun navigation challenges, route finding, terrain reading, and other Spring Snow delights.

Gotcha
On the fourth day, as we were working our way from Meiss Meadow down to Round Lake, I heard a coyote coming through the underbrush, and even caught a glimpse of her before she heard or saw us.

I signaled for complete stop and silence, then pointed to my estimated point of emergence from the underbrush of the coyote, who soon popped through the spot I anticipated.

Yosemite Announces Delayed Facility Openings, & Beware Snow-Covered Trails through July

MONSTER SNOW PACK of the WINTER of 2019

Seasonal News of Note
Yosemite Announces Delayed Facility Openings

Note the Snow will Affect High Trail Access, & Damages will Affect Trails Too

Yosemite National Park Announces Late Seasonal Openings for Several Park Facilities,
Yosemite National Park, March 13, 2019.

MAIN POINTS

Damaged Facilities
“...that there will be late seasonal openings to facilities throughout the park...due to the exceptionally heavy snowpack in Yosemite National Park and the subsequent extensive damage to many park facilities.”

Stormy Winter
“...significant storm systems in January and February produced high levels of snow, which resulted in temporary road closures, rock and debris slides, and falling trees. Additionally, these storms resulted in extensive damage to facilities throughout the park. Damage to facilities includes trees falling on and damaging campground restrooms, utilities systems compromised, tent cabins damaged or destroyed, and falling trees impacting campsites, parking areas, hiking trails, and roads.”

Backpacking out of the snow-filled Tahoe Basin 3: Day 2, Burnt Area Camp to Round Lake

Day One, Campsite One: A tour of the location of my campsite on the burnt flat area relative to Big Meadow, the South Upper Truckee's Eastern tributary,  and Meyers down the valley.

(Map, Miles, Elevations, Video & Trail Guide info below)

After arriving at camp I leave on my pack and snowshoes to better stamp out flats for my sleeping pad and sleeping bag, as well as to compress a bit of space that I can cook and kick back in. If I do not do this, I will endlessly post hole when I take off my snow shoes. When you compress soft snow it tries to refreeze, and if you are lucky it will hold up your weight without snow shoes after a good compression session.

The Character and Evolution of the High Sierra Winter into the Spring of 2019

 

SETTING a SEASONAL “MARKER”

Almost Dead-Average Snowpack

February 2, 2019
The salient point today, the second of February, is we’ve got a seasonal normal, “average,” snow pack (calendar), while looking at a set of moderately powerful storms coming through, all playing out in the wake of the disruptions created by the great movement of the Polar Vortex, off the top of the planet to center its spin over the North end of Hudson’s Bay, over the past couple of weeks.

Today we can see the Polar Vortex has split into thee, "vortexes," with the one over Hudson's Bay, the one that brought so much frigid Arctic cold air to the South, has weakened in favor of the Vortex to its North:
