BIG WALL CAN
Leave No Trace® wilderness ethic suggests
we take every action possible to reduce our impacts
on the environment over which we travel. What
to do with human waste is always a concern. Rock
climbers and big wall climbers have practiced
pack it in, pack it up & out for years. This is
a requirement in Yosemite!
BIG WALL CAN is an adaptation of the Clean Mountain
Can sponsored by the American Alpine Club and
The Access Fund originally used in Denali N.P.
It is washable and reusable as defined by the
Bureau of Land Management, National Park Service
and National Forest Service. Most importantly,
it is light weight (just over 2 lbs!) and easy
to pack or haul. There are two options for use:
- Unscrew the lid, hover and do your business
- this requires a rock ledge or portaledge (do-able)
and mad balance skills. In all cases be sure to
keep yourself and the BWC on belay! The result
of several days "deposits" is a slurry of waste
that can be emptied directly into flush toilets,
pit toilets or RV Sanitary Stations (located near
Upper Pines C.G. in Yosemite). Various organic
and chemical additives are commercially available
to accelerate biodegradation and reduce odor.
Add a small amount if you wish before the start
of your climb. See
Yosemite N.P Climbing Regulations for this
and other useful details.
Big Wall Use
- Most climbers
will want to do "number two" in a small brown
paper bag (degradeable) then roll it up and place
in the Big Wall Can for transport. Bags can be
pre-rigged and stashed with a small handful of
kitty litter to cut the smell and absorb liquids.
Empty this in to a pit toilet (not a flush toilet)
or RV Dump Station once down from the wall. Similarly,
take GO-ANYWHERE (aka WAG) BAGS (1.5 bags / day
per climber) - which come with TP, sanitizer and
waste bag. These can be disposed of in trash bins
and will degrade in the landfill. Make every effort
to pee into a bottle carried on
the climb for this purpose or reuse water bottles (marked accordingly). On 1-2 day routes either can be emptied into the Big Wall Can for secure transport.
& Back Country Use
- If you
travel with a group and congregate in one area
or site (guided climbers, river trips, trail crews,
fire fighters, construction & utility workers)
consider using a BWC for communal use. This should
be one of the responsibilities of the guide, crew
chief or supervisor. The BWC can be carried in
hand, strapped to a pack or carried inside one.
- After use,
clean the Big Wall Can with a mild soap and water
solution and a little bleach.
