I assume that ground water, whether stream or lake, has Giardia and/or
Cryptosporidium in it. I have never yet seen a definitive answer in the
affirmative to the question "Does iodine, in any form, kill Giardia or
Cryptosporidium?"...
Since I've fairly certain that answer will never come forward, the answer is
to filter water with a water filter that has an absolute pore size of .3
microns or less. MSR Mini-works have that specification. I don't leave
home without it...
Left the Polar Pure in the locker on my Philmont trek, since I was fairly
certain that I would not encounter any virus contamination in the water at
Philmont.
Heresy.. Naw, no really.... But consider a different alternative... For the
cost of Philmont (travel +) for those of us in California, we could do 3
outstanding trips to the Sierras.
But..............
It's not Philmont.. There is only one... And I hope to go back in 2005.. And
I'll do the Sierras in the meantime...

Philmont Comments / Trek 15 / Crew 710G1
Water Filter - without our MSR filter we would have had NO potable
water at Bent our first night. Rain had put so much silt in the stream as to
make it
unusable (yes we tried filtering it through bandannas, letting it sit
overnight, etc. Didn't work).
Our ranger had no idea what to do (other than the filter).
I've been on two treks and would never rely on just PolarPure.
Heresy - Having done both Philmont (twice) and Boundary Waters, I MUCH
prefer Minnesota and a canoe
(so do all the scouts in our troop who have done both).
