You absolutely must have everything on this list (unless it's marked optional), or you cannot go on the trip. No exceptions without speaking to the trip leader. You should not need anything in addition to what is on the list. Please speak to the trip leader if you are bringing anything else of any substantial weight.
pack
(internal
or external, ideally a relatively small pack, to save on weight, e.g.,
3000-4000 cu. inches, 4-5 lb; internal easier to check safely on airline; wrap
in heavy plastic bag secured with duct tape for checking on airline; bring
along a second heavy garbage bag and extra duct tape to do the same for the
return flight)
waterproof pack cover (garbage bag is not adequate in a wind storm; it
will tear)
sleeping bag (20 F rating, 2-3 lb; should be down or good quality synthetic
insulation such as Polarguard 3D, so that it compresses into a small stuff sack)
foam sleeping pad (compact and lightweight; either open cell foam, e.g.,
Thermarest, or closed cell foam, e.g., Z Rest or Ridge Rest)
tent (5 lb lightweight 2 person tent is best, with each person sharing
with someone, so that each person only carries about 2.5 lb of tent)
4- liter capacity water container(s), e.g., two 2-liter soda bottles (Nalgenes
are only 1 liter, and so you would need 4 of them; 4-liter bladder might be an
alternative))
plastic eating bowl, plastic drinking cup, spoon (and fork if you want)
rain jacket (as lightweight as possible, but water proof, not just water
resistant; Goretex or equivalent best, but coated nylon OK; rain pants not
needed)
hiking boots (medium weight, and worn in)
wading boots/shoes (best would be old, but good fitting, running shoes
or hiking boots)
lightweight
camp shoes (optional; some people like to change into other shoes, e.g., tevaz, at
end of day; this may be overkill, as you will have hiking boots and wading
shoes, too)
brimmed hat/cap (something to keep the sun off your face; what works
well is sewing cloth on back of baseball cap to cover ears and back of neck)
socks, 3-4 pairs (synthetic hiking socks; your option to also bring
liner socks; you’ll wear socks in your wading shoes as well as your hiking
boots)
fleece jacket (long sleeve; this is a key item, as it is what will keep
you warm at night and early morning if weather is cool; fleece is necessary, as
it will dry out quickly)
long pants, 1 pair (synthetic, e.g., nylon; conceivably, you could
substitute a second pair of shorts)
shorts, 1 pair (synthetic, e.g., nylon)
T shirts, two (both could be synthetic, but one, for wear in camp, could
be cotton; synthetic shirts can be washed and hung up to dry each night since
synthetic will dry quickly)
underwear, 2 pair (optional; OK to bring, but because they are cotton they
can be a problem if you get wet, and not necessary if you wear hiking pants
with built-in underwear)
sunglasses (essential, given bright sun)
sunscreen (essential, but we should
share containers)
insect repellent (unlikely to be needed; we should bring one container
for whole group)
personal first aid kit (e.g., in a zip lock bag) containing: moleskin, duct tape, band aids,
ibuprofen or other pain relieving pills, sunscreen (we should share containers
of this); chapstick (optional), any prescription medicines you might need on
trek. The adult leader will carry more
complete troop first aid kit.
personal
emergency gear kit (e.g., in zip lock bag) containing:
nylon cord (25 ft. of 1/8 to 3/16"), matches (with strike pad) in
waterproof container, pocket knife, compass, whistle, paper, pencil, two
garbage bag
toilet paper or tissues in a zip lock bag
zip lock bags, 2-3 midsized (one for packing out toilet paper and trash; others for just in
case)
plastic toilet trowel (for digging "cat hole" for burying human
waste; could share this with others)
toiletries (this is up to personal preference, but some may find that the
following is good: toothpaste, toothbrush, hair brush/comb, liquid soap in a
small container, wash cloth in a zip lock bag, small towel)
headlamp (with fresh batteries, and possibly extra batteries; headlamp is
much better than a flashlight, for working in camp and for hiking should an
emergency require night hiking)
camera (optional)
map (this will be supplied)
travel
bag
(optional; something to carry aboard airline, with stuff you want to have on
the flights; will also serve as a place to put your travel clothes while
hiking)
travel
clothes
(optional; clothes to wear on trip out, and to change into--after a shower we
hope--for trip back)
