Welcome to the High Sierra Backpacker's Magazine, including forums for local and long-distance hikers sharing info about hiking the Sierra between Tahoe and Whitney.

This Magazine covers everything Sierra. Its
Forums cover TYT, PCT, & JMT and alt-route hiker input from the Guide. The Tahoe to Whitney Trail Guide explores the trails  & the necessary skills, fitness, and gear required to hike from Tahoe to Whitney. This evolving Magazine covers Current Conditions, News, the Arts, Sciences, Physicality, Spirituality, Gear, Environment, History, and Cultures of hiking Tahoe to Whitney. 

Purposes: Expand Knowledge, Explore Potential

for Beginners: To get you off the couch, gear you up, get you into Sierra Shape, and onto the High Sierra Trails. Find info. Ask questions, get feedback, generate self-understanding and terrain awareness. Find killer short routes up and down the High Sierra Crest.

for Backpackers: Get you in deeper, longer, and higher. Train for the long trails. Find your next-steps trips. Hit the Long Trails. Hike the TYT and JMT. Find and explore side trails, alternative, and cross-country routes until you hike your skills into Winter compentency. Explore your potential.

for Experts: The information to come from anywhere in the US or world and backpack from Tahoe to Whitney. The Sierra Nevada is the ultimate wonderland for expert backpackers in top shape. But don't get cocky! The Sierra is bigger, stronger, and has been, and will be here much longer than any of us.

News of Climate & Ecological Change, The Summer of 2019





Updated Daily 

June 21,  2019


Summer of 2019

The transitions between seasons, their basic character, their timing, temp, and humidity transitions have all changed. The directions from which the seasonal winds blow have changed. These changes are reverberating through and disrupting webs of life that wrap around the whole planet.

Blooming, feeding, mating, and migration patterns of all living things are changing around the world.

Here we track the obvious and the subtle human affects on Nature. The club and the knife, if you will.

Bacteria Defeats Last Effective Antibiotic



Salmonella Resistant to Antibiotics of Last Resort Found in US.
North Carolina State University, June 13, 2019.

MCR-3.1 in US
"...found a gene that gives Salmonella resistance to antibiotics of last resort in a sample taken from a human patient in the U.S. The find is the first evidence that the gene mcr-3.1 has made its way into the U.S. from Asia."

Full Antibiotic Resistance
"The drug resistance gene in question - known as mcr-3.1 - gives Salmonella resistance to colistin, the drug of last resort for treating infections caused by multidrug-resistant Salmonella."

2019 Dead Zones at Record Size & Expanding



Dead Zones at Record Size & Expanding

1>Gulf Mexico --&-- 2>Chesapeake Bay


1>Gulf Mexico

2019 'Dead Zone' may be the Second Largest on Record,
Louisiana State University, June 10, 2019.

Main Points

Second Biggest on Record
"A recent forecast of the size of the "Dead Zone" in the northern Gulf of Mexico for late July 2019 is that it will cover 8,717-square-miles of the bottom of the continental shelf off Louisiana and Texas. The unusually high Mississippi River discharge in May controls the size of this zone, which will likely be the second largest zone since systematic measurements began in 1985."

"The water mass with oxygen concentrations less than 2 parts per million forms in bottom waters each year primarily as a result of nitrogen and phosphorus loading from the Mississippi River watershed, which fertilizes the Gulf of Mexico's surface waters to create excessive amounts of algal biomass."

Under Counting on the Ground--BUT--Everything Counts Up in the Sky

Fertilizer Plants emit 100 times more Methane than Reported,

Fertilizer Plants
Methane Emissions

> "...100 times higher than the fertilizer industry's self-reported estimate."

> "...higher than the Environmental Protection Agency (EPA) estimate for all industrial processes in the United States."

Self-Regulation & Reporting
"It shows us that there's a huge gap between a priori estimates and real-world measurements."

Natural Gas
"...use of natural gas has grown in recent years, bolstered by improved efficiency in shale gas extraction and the perception that natural gas is a less dirty fossil fuel."

Your Digital Dead-Weight Brain in our Brave New Digital World




Your Digital Deadweight Brain

Research reveals how the Internet may be changing the brain,
NICM Health Research Institute, Western Sydney University, June 5, 2019.


Cell Phonyism
"The key findings of this report are that high-levels of Internet use could indeed impact on many functions of the brain."

Stupid Phones
"...international team of researchers...have found the Internet can produce both acute and sustained alterations in specific areas of cognition, which may reflect changes in the brain, affecting our attentional capacities, memory processes, and social interactions."

Individual and Social Effects
"Instagramification of society"
"I believe that this, along with the increasing #Instagramification of society, has the ability to alter both the structure and functioning of the brain, while potentially also altering our social fabric."

Digital Hole
"It's clear the Internet has drastically altered the opportunity for social interactions, and the contexts within which social relationships can take place."

American Chemical Society, June 5, 2019.


Human Test Subjects
"...the average American consumes more than 70,000 particles of microplastics per
year, though the health effects of that consumption are unclear"

74,000 to 121,000 Particles Per Year
"...estimated microplastic consumption ranged from 74,000 to 121,000 particles per year, depending on age and sex. People who drink only bottled water could consume an additional 90,000 microplastics annually compared with those who drink only tap water."

173 African Cities
"...a range of possible scenarios regarding the rate of climate change and socio-economic development in 173 African cities for the years 2030, 2060 and 2090."

Population Growth & Urbanization
"...highlight the influence of socio-economic development on the impact of climate change."

Lethal Combination
"...Africa - are experiencing heavy urbanisation and socio-economic development, leading to an explosion in the size of urban populations. A combination of these two factors is having a major impact on the living conditions of city-dwellers in Africa, especially in terms of exposure to extreme - or even lethal - temperatures."

Measuring Unbearable
"...calculate the number of people per day exposed to apparent temperatures above 40.6°C (105°F) in cities in Africa on an annual basis."

HEALTH & FITNESS: Coffee Reduces Death

Coffee Cleared of Stiffening Artries



Coffee Reduces Death

Research suggests coffee consumption associated with reduced risk of death,
Institute for Scientific Information on Coffee, July 31, 2018.

Less Death for Coffee Drinkers
“...presented unpublished original research studying a cohort of almost 20,000 participants over an average of ten years...research suggests that coffee consumption at intakes of 3-6 cups of coffee a day reduces all-cause mortality. Within this cohort, there was a 22% lower risk of all-cause mortality for each two additional cups of coffee per day.”

Not Just the Caffeine
“...suggested that caffeine alone was unlikely to explain the effect on mortality, mentioning a potential role for polyphenols found in coffee, which may have antioxidant and anti-inflammatory effects.”

Less Death
“Meta-analyses have suggested that coffee consumption versus no coffee consumption is associated with an up to 17% risk reduction of all-cause mortality.”
