Happenings in the relationship between Man and Nature affecting our hike down life's trail through both worlds. We study both the reality created by humans and the uncreated reality reflected in, and tended by Nature. 

The vast majority of our reporting on Nature comes from the American Association of Scientists summarizations of each day's bounty of the peer-reviewed research published by academic institutions and journals around the world.

High Sierra Day Hikers & Backpackers

Springing!
Spring has come to the eastern Sierras and time to spring clean the first aid kit. Alex has provided excellent information about his first aid kit in the gear list.

Day Use
I am an avid day hiker, so the contents of my bag are a bit different. I also have extensive medical training and access to prescription drugs, so I try to keep stuff to help out others on the trail. This is the time of year I pull the first aid kit from the depths of my day pack and inspect and refill the contents. My bag is not huge and contains all the things I need to survive the sun, rain, cold, bugs and injury/illness for a few days.

Injuries Encountered
The injuries that I have encountered on the trail are blisters, splinters, cuts and scrapes and the occasional laceration that needs stitches. The illness that I have encountered are mild cases of upset stomach, sunburn, bug bites, sore/strained muscles, heat exhaustion and high altitude sickness.

Watch Out for the Green Water: Blue-Green Algae News and Safety Information sticky icon

Watch Out for the Green Water

 Do not drink, or allow your animals or children to drink from or play in water containing cynobacteria, otherwise known as toxic blue-green algae. Review the Blue-Green News just below and the safety information at the bottom of this page:


Blue-Green Algae Safety and Identification Information

 

July 2018,
&
August 2015:
Rising heat and declining waters are creating conditions even more favorable for cynobacteria,otherwise known as toxic blue-green algae.

In the Sierra the source of nitrogen feeding the blue-greens is cattle grazing. This is the same grazing that preserves High Sierra meadows, and for which the series of check dams that gave birth to countless lakes were created.

Our goal here is to provide the best information how to deal with internal and external threats to your health. But why?

 

FIELD GRADE
Our greater goal is to attain "Field Conditioning." Field Conditioning is an advanced state of fitness where we are capable of moving and operating effectively across great distances over all types of terrain, at high or low altitude, in hot, cold, wet, or dry conditions over extended time spans, under all seasonal conditions, while carrying the weight required to withstand these environmental conditions, feed ourselves well, and safely reach our goal.

Bear News and Research sticky icon

 

The repository of Bear news, research, and stories we come across.

I've written about my experiences with High Sierra Black Bear Behavior in the Trail and Camp Skills section of the Trail Guide. Remember, bears act differently in different locations, and can be quite unpredictable in most situations.

Most times we can figure out what they want, and that typically boils down to two things: Food, and/or to be "left alone." Bears have personalities and feelings, which make them almost as unpredictable as that most deadly of beasts, humans. Almost...

The World of Insects and the Spiders that Eat Them

We've got worlds of wonder in the High Sierra looking in any direction. The ground and sky are full of vibrant insect communities. Some, like the mosquitoes, are winged devils. Others are winged delights. On the ground we find spiders trying to catch and eat them all.

This forum started out as the Spider Forum, but has been expanded to include the various insects we encounter that are not Bees, Butterflies, and Mosquitoes, which have their own dedicated pages.

High Sierra Nevada All Living Things Forum

 

 

BUTTERFLY NEWS
 The whole web of life is being distorted by the  changing character of the seasons on and around the the vastness of the North Pacific Ocean.

 The Sierra Nevada Mountain Range is a significant element in the complex relationship of the North Pacific Ocean weather patterns with the North American continent.

 The relationship between North Pacific weather patterns and the High Sierra is vitally important for the vast overlapping webs of social and natural life depending on bountiful and predictable weather patterns.
These predictable and bountiful resources no longer exist on their own, in Nature, nor in the context of the vast populations to overwhelm Nature that we have spawned.

We have overwhelmed Nature and its resources fundamentally and on its face..

The last major quake in California was just over a hundred years ago, with the SF Quake measuring in at 7.9. Loma Prieta was 6.9, in 1989.

 

Long Gap of Major California Earthquakes

WATER, ICE, OCEANS, GLACIERS & FISH

April 1, 2019 High Sierra Snowpack Survey

Snow Survey Boosts Runoff Predictions,
Cal Dept Water Resources, April 2, 2019.

MAIN POINTS

“The April results are a key indicator for the rest of the year’s water supply.”

“Sierra Nevada snowpack is 162 percent of average”

“California has experienced more than 30 atmospheric rivers since the start of the water year, with six in February alone...”

“Based on snowpack numbers, we have the potential for some minor flooding due to melting snow so we remind folks to always stay vigilant and aware.”

Too Much Water
“The state’s largest six reservoirs currently hold between 106 percent (Oroville) and 132 percent (Melones) of their historical averages for this date. Lake Shasta, California’s largest surface reservoir, is 109 percent of its historical average and sits at 89 percent of capacity.”

WEATHER

Winter of 2018-2019

What Happened? What’s Next?

Just how wet and cold was winter 2018-2019?
Weather West, March 24, 2019.

MAIN POINTS

Start
"...punctuated by California’s deadliest and most destructive wildfire in history during the uncharacteristic month of November."

Seasonal Precip
“Overall cumulative precipitation anomalies have not been particularly exceptional...”

Seasonal Temps
“...temperatures for the full period really haven’t been that cold–shaking out pretty close to average for most of the state. (Of course, that somewhat masks the very cold conditions that occurred during February).”

The Question
“So how, exactly, can California have received 156% of average snow water equivalent when precipitation over the same interval was only ~120% of average and temperatures were “near average?”
