Ok… Now remember the Ten Backpack Essentials? They are
listed at the bottom of this article in case you forgot.
Lets talk about the first item on the list; Hydration.
You can never carry too much water… well almost. Water is
pretty heavy so most people don’t want to carry very much.
The trouble is that out here in the Great South West there
usually isn’t very much water laying around out there where we
go on missions. So you have to carry enough water with you to
last as long as you expect to be out on a mission and then
some more for the unexpected. Here is an interesting web page
on water consumption by the Mayo Clinic:
http://www.mayoclinic.com/health/water/NU00283
Another web site with recommended water consumption while
hiking the Grand Canyon is put out by the National Park
Service:
http://www.nps.gov/grca/planyourvisit/hike-smart.htm
Note- Their 10 Essentials list is a little different than ours
but basically they cover the same things.
************************************************************************
Here is an excerpt from that web page:
YOU SWEAT AROUND 1/2
TO 1 QUART OF FLUID FOR EVERY HOUR YOU WALK IN THE HEAT.
This fluid/electrolyte loss can exceed 2 quarts per hour if
you hike uphill in direct sunlight and during the hottest time
of the day. Because inner canyon air is so dry and hot, sweat
evaporates instantly, making it’s loss almost imperceptible.
Keep an eye out for salt rings on your clothes.
Do not wait until you are feeling thirsty to
start replacing fluids and electrolytes. By the time you feel
thirsty, you are already dehydrated.
Even a mild level of dehydration can make hiking a lot less
fun. The more dehydrated you become, the less efficient your
body is at cooling making hiking more difficult.
Your body can only absorb about 1 quart of fluid per hour, so
drink ˝ to 1 quart of fluids every hour that you are hiking in
the heat. Carry a water bottle in your hand and drink small
amounts often, alternate between water and a sports drink with
electrolytes.
Balance your food intake with fluid
consumption, else you run the risk of becoming dangerously
debilitated and severely ill.
Food is your body's primary source of fuel and salts
(electrolytes) while hiking in the canyon. Eat a salty snack
every time you take a drink.

A
great way to carry water is a Camelbak :

You
don’t have to stop to get a drink of water. You just grab the
tube hanging on your shoulder and take a sip as you go. Some
Camelbaks also double as a small day pack so you can carry
your other essentials in it as well.
Don’t forget to carry electrolytes. Some options are
Gatorade, electrolyte tablets (
http://www.rei.com/product/761714
), salty crackers or other salty foods. Most experienced
hikers recommend that you dilute Gatorade with an equal amount
of water to reduce the salt and sugar content to a less/better
concentration in the mix.
Don’t over do! Too little water is bad… too much water is
bad… too little electrolytes are bad… and too much
electrolytes are bad. Below is an excerpt from the National
Park Service web page on hiking the Grand Canyon. (Even
though this was written for the Grand Canyon it applies
equally to Us here in Rim Country.)

The Hazardous H's
WATCH OUT FOR THESE
HEALTH HAZARDS!
HEAT EXHAUSTION - The
result of dehydration due to intense sweating. Hikers can lose
one or two quarts (liters) of water per hour. Rangers at
Phantom Ranch and Indian Garden treat many cases of heat
exhaustion each day in summer.
Symptoms: pale face,
nausea, vomiting, cool and moist skin, headache, cramps.
Treatment: drink
water with electrolytes, eat high-energy foods (with fats and
sugars), rest in the shade for 30-45 minutes, and cool the
body by getting wet.
HEATSTROKE - A life-threatening emergency where the
body's heat regulating mechanisms become overwhelmed by a
combination of internal heat production and environmental
demands. Your body loses its ability to cool itself. Grand
Canyon has two to three cases of heatstroke a year. Untreated
heat exhaustion can lead to heatstroke.
Symptoms: flushed
face, dry skin, weak and rapid pulse, high core body
temperature, confusion, poor judgment or inability to cope,
unconsciousness, seizures.
Treatment: the
heatstroke victim must be cooled immediately! Continuously
pour water on the victim's head and torso, fan to create an
evaporative cooling effect. Immerse the victim in cold water
if possible. Move the victim to shade and remove excess
clothing. The victim needs evacuation to a hospital. Someone
should go for help while attempts to cool the victim continue.
HYPONATREMIA (water intoxication) -
An illness that mimics the early symptoms of heat exhaustion.
It is the result of low sodium in the blood caused by drinking
too much water and losing too much salt through sweating.
Symptoms: nausea,
vomiting, altered mental states, confusion, frequent
urination. The victim may appear intoxicated. In extreme cases
seizures may occur.
Treatment: have the
victim eat salty foods, slowly drink sports drinks with
electrolytes, and rest in the shade. If mental alertness
decreases, seek immediate help!
HYPOTHERMIA - A life-threatening
emergency where the body cannot keep itself warm, due to
exhaustion and exposure to cold, wet, windy weather.
Symptoms:
uncontrolled shivering, poor muscle control, careless
attitude. Look for signs of the "umbles" - stumbling,
mumbling, fumbling, grumbling.
Treatment: remove wet
clothing and put on dry clothing, drink warm sugary liquids,
warm victim by body contact with another person, protect from
wind, rain, and cold

The Ten Backpack Essentials
These are the basic things every
backpacker should have in their pack when they go out hiking.
This list applies to anyone whether they are hiking just for
fun or going on a SAR rescue mission. SAR members who do not
have these basic things with them may be putting themselves
and/or others at risk and may be making themselves a potential
liability instead of an asset on a mission.
1. Hydration
Camelback, Water bottles and
Water, Water, Water!
Electrolytes
Water Filter or other water
treatment system (optional)
2. Nutrition
Extra days supply of food
Energy food ( energy bars, trail
mix, etc.)
3. Fire
At least two ways to make fire (
lighter, waterproof matches, flint & steel, etc.)
Fire starter ( dryer lint,
Vaseline cotton balls, commercial fire starter sticks, etc.)
4. Sun Protection
Sunscreen and lip balm
Sunglasses
5. Knife and Tools
Pocket knife, Leatherman,
compact hand saw, etc.
6. First-aid Kit
7. Illumination
Headlamp or flashlight with

GPS ( Optional as part of this
list but essential for SAR)
9. Insulation and/or body covering
Extra clothing appropriate for
the location and time of the year ( Jacket, socks, pants,
Rain gear, etc.)
10. Emergency Shelter
Tarp, tent, bivy, space
blanket, cord, webbing, duct tape - basic things necessary to
make an emergency shelter.
The list above assumes that you have
dressed appropriately for the location and the time of year.
Appropriate dress would include:
1. Hat - To protect you from the
Sun, rain and/or keep your head cool or warm.
2. Gloves
3. Sturdy Footwear adequate for the
climate and time of year.
4. Clothing suitable for the climate
and time of year. Preferably synthetics in layers that can be
added to or removed that wick perspiration from the body and
helps to control body temperature. Clothing that protects you
from the sun or rain, heat or cold, etc.
5. Wrist watch or some
other reliable timepiece.
