I believe that will work fine, until you hike near glaciers..

Run water from this beast through it:




That's the Brazeau river in Jasper NP, just the other side of nigel pass. while not unique
for mountain parks at all, I use this particular example, because there were three other
groups there with water filters. and me with my pristine (aquamira clone). I treated water
for everyone. Why? the lovely medical grade ceramic filters would clog solid with rock flour
(the really really fine stuff the glaciers grind off the rocks) after about a half litre, and no amount of scrubbing would clear them. So after three clogged filters, one of which was busted by the party involved in a desperate attempt to clean it, everyone just shuffled over to the fat guy in the hammock to get the stuff that works. (well, one used up a ton of fuel boiling it...)

(did I mention I have a hate on for filters? <img src="/forums/images/graemlins/smile.gif" alt="" /> - they're heavy and unreliable <img src="/forums/images/graemlins/smile.gif" alt="" />
