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.

The Fundamental Nature of Reality Big to Small... 

We follow Astro-physics and Science for fun, because the Nature of Life itself is pretty darn entertaining on its own merits. Understanding the Nature and construction of our reality is a pragmatic move for all its "operators," but especially for backpacker's finding context in, and navigating the terrain to both ascertain & clarify our place in the Universe.

Filters and Purification: MEMBER's FAVORITES for High Sierra Backpacking

 Member's Favorites

What are, and how do we select the best Water Filtration, Purification, Treatment, and Usage System for High Sierra backpackers?

The fundamental requirement for me is clean water quickly. By clean I mean taste as well as purity, so chemicals are regaled to emergency status.

Next, I want to purify as little water as possible. I will filter only the water for drinking, while my cooking and cleaning water will remain unpurified. Thus I need a system to bring unfiltered water to camp for cooking, cleaning, and to provide stock for purified water.

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

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.

Forty Day Backpacking Plan: Lake Tahoe to Mount Whitney 2002

2002 Tahoe to Whitney 40 Day Backpacking Trip

Planning and Execution Notes

Below we have one element of my trip planning notes from a forty day hike I took from Lake Tahoe to Mount Whitney during 2002.

I've done Tahoe to Whitney Trips in 1999, 2001, 2002, 2009, and 2012. Injury is the determining factor in my "backpacking year" scheduling. If I am fit I am backpacking.

The backpacking plan is both a plan that determines what each resupply bucket will contain, and is my selection of nightly campsite locations.
It lists the dates and locations I expected to camp each night. It lists when and what I was going to pick up my resupply buckets, and was my shopping list for additional items I needed to get.

Note that I made this list in May of 2002 for departure on July 9. It was in May that I brought together all my food for packing into resupply buckets to begin shipping. This is the point where my itinerary came together to determine my exact food needs. The schedule and the food planning must come together simultanously.

Backpacking Tent Selection

Backpacking Tent Selection
Nowadays there are two basic schools, or philosophies, of backpacker tent use: Lightweight or None. These are not mutually exclusive catagories.

I typically fit into both categories, depending on the circumstances. Oh, and my five pound tent also likely puts me in what most would consider as using a, "heavyweight" tent, too.

Mosquitoes and Seasonal Temperature Shifts

Two important things about the changing seasons in the High Sierras
    Two deeply interrelated realities strike me as being very important to average backpackers about the seasonal temperature changes in the High Sierras. The first concerns shifting your gear with the changing temps. The second is the High Sierra Mosquito Cycle.

Both shifts follow the annual temperature rise in Spring to Summer temps, and the subsequent drops in temp at the end of Summer to Fall and Winter conditions.

After 40+ years backpacking Sierra...still too many places to see. Working now in Tuolumne Meadows store is a 2-edge sword...Great central location but only 3 days a week to do art and explore. Still. kind of like the views from outside the office.
