It is likely that the GPS would refuse to work in a snow storm in the
forest. They really are very sensitive to anything that interferes with
their view of the satellites. Even heavy clouds can cause them to have
trouble locking on. However, if you've been stopping in clearings and on
ridge-tops setting waypoints on your way in, you can look at your last
known position and make a good guess using the compass as to what way you
should be going. And the "breadcrumb" feature on the eTrex certainly does
work, I use it regularly when I'm doing in-and-out day hikes in areas
where GPS works (remember, it does NOT work under a forest canopy!).
A map and compass work 100% of the time. A GPS doesn't substitute for
them, it only augments them. We still are nowhere near the magic
technological solution that can with 100% certainty tell you where you are
under any conditions.

Cell phones generally don't work once you get more than 20 miles from an
Interstate highway. You'll need to think about renting a sat phone if this
is what you're interest in. Note that sat phones have much the same
limitation as GPS -- they need a clear, unobstructed view of the southern
sky in order to find the satellite.

The locator beacon thingy mentioned elsewhere probably would work better
than a sat phone, it works under more conditions. On the other hand, I've
never gotten to the point where I would need either, so I'm not really
qualified to say which would work best. I once got turned around in the
forest (due to not looking at my GPS or compass since I "knew" where I was
going), and found myself miles off course and out of water. After a couple
of minutes of hyperventilating where I considered going to the next
ridgetop and screaming for help on my cell phone, I instead navigated to
the next water source, used my hiker's water filter to filter some scummy
spring water into drinkable water and filled my water bottles, resigned
myself to the fact I was going to be in the forest for a day longer than
I'd expected, and started hiking back out (using the GPS and compass this
time).
I similarly carry enough gear on my KLR when I go into the backcountry
that I could hike out if necessary. I'd be pi$$ed if I had to do so, but
if it is a choice of my survival or that of my KLR, I'd pick my survival
every time. Yes, this means I'm carrying over $500 worth of hiking gear on
a motorcycle trip (sigh). But at least if you go the ultralight route, the
required gear doesn't weigh much or take up much space and easily straps
to the KLR.
