Re: [John Muir Trail] Bears
You raise a good point re: effectiveness of hand sanitizers and whether
they can substitue for hand washing.
Here is an article I found in the New York Times on the topic:
The most important paragraphs for our discussion are:
"Since 2002, officials at the Centers for Disease Control and Prevention
have recommended that health care workers routinely use high quality
alcohol-based gels instead of soap and water on their hands when moving
from patient to patient as long the worker's hands aren't visibly soiled.
Alcohol doesn't cut through grime well, so dirt, blood, feces or other body
fluids or soil must be wiped or washed away first, if the alcohol in the
sanitizer is to be effective. In such cases, hand washing with soap and
water is advised."
So, sanitizers would work (so long as they are 60% alcohol) unless you are
too dirty or get the icky stuff on your hands, in which case its soap and
water. Plus, sanitizer.

I disagree with Herb about the soap. Hand sanitizers are nowhere near as
effective as soap at getting rid of the ickies that can cause GI problems
for your entire group. And hand contamination is reportedly much more
likely to cause sickness than are water quality issues like Giardia. I just
wash my hands with an hopefully biodegradable soap as far away from a water
source as possible - I just use water from my water bottle to wet my hands
and then to rinse.
Hand sanitizers *might* be a backup to soap for the times when you are too
tired to do a good hand wash. I carry a little. But I'd never rely on it
after making a deposit in the woods. I try to wash right away with soap and
water. If I can't (e.g., I've already emptied my water bottle) I would
definitely wash before handling any food or messing with a water pump.
I'm hoping someone on the group is enough of a microbiologist to comment
intelligently, since I suspect I am more dubious about hand sanitizers than
But is we can't find an expert, this seems to be good info on this:
links provided there.
From a Purdue researcher: "[R]esearch shows that [sanitizers] do not
significantly reduce the overall amount of bacteria on the hands, and in
some cases they may even increase it."
From a FDA research summary: "The instant hand sanitizers resulted in a
significant *increase* in bacterial numbers on hands."
Not everyone is so negative on hand sanitizers. But the most optimistic
opinion I've read (on an admittedly not-thorough search) is this:
"According to research performed by the U.S. Centers for Disease Control and
Prevention, hand sanitizer is considered as effective at killing germs as
washing your hands with soap and water, *unless hands are visibly soiled*."
I find that my hands usually are "visibly soiled" on the trail, so even the
optimistic view is not encouraging.
I find a 1-oz bottle of the standard liquid campers soap ("Campsuds" - the
green stuff) lasts me a week on the trail. And I use it on cooking utensils
and clothes as well as on hands. My theory is sue sparingly but often.

- I don't know how high the density of bears is in SNP, but, living in the area myself and having hiked there many times, I was disappointed for several years at not having encountered any there. I finally had my first sighting last year, followed by another one 5 minutes later, then a mother and cub shortly after that. So, I saw 4 bears just in the one hike, all within about 20 minutes. That was really exciting.
Shenandoah National Park, where the black bear density is very high, also permits the use of spray although I cannot imagine why anyone would feel the need to use it. All of the bears that I've seen are more timid than deer. After hiking the JMT without a bear sighting, I had a bear encounter at Shenandoah at few weeks later and another one in April. Both times the bears ran as soon as they detected my presence.
