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.

Safety First! First Aid Kit for High Sierra Backpackers sticky icon

 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. 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.

Climate Change Triggering Return of New, & Eradicated Mosquitos & diseases

CLIMATE, SKEETERS, & HEALTH

It’s Already Happening...

Could climate change trigger the return of eradicated mosquito-related disease?
University of Bath, November 5, 2018.

MAIN POINTS

New Ranges
“The largest ever study of the mosquito evolutionary tree, going back 195 million years, suggests that present-day climate change could result in the spread and return of dangerous mosquito-borne diseases to new places or areas where they had previously been eradicated.”

Return of the Classics
“...– including malaria, Yellow fever, Zika virus, and Dengue fever – cause millions of deaths each year. While many of these diseases have been eradicated from Europe and are under control in other parts of the world, resurgence is always possible.”

Bonus for the Skeeters
They Like Heat AND CO2
“...the rate at which new species of mosquitoes evolve generally increases when levels of atmospheric carbon dioxide are higher. This is concerning because the greater the number of mosquito species, the more potential exists for new ways of vectoring diseases, and perhaps for new variants of those diseases.”
