Yes indeed. the canadian brand name is "Pristine" - it's the same thing as Aquamira - chlorine dioxide. Works fast (on anything you're gonna find in the canadian rockies) and is impervious to silt.

I've drunk lots of glacial silty water. if it's *really* silty it's nasty, but by "really silty" that's usually the stuff that's literally meters from the feet of the glacier. So for example here:



I didn't take that water - instead I just hiked up to the glacier and collected some melting off the top (instead of coming out of the bottom) of the glacier).

Now, having said that most of the time, I have no problem at all. The "normally" silty water, I have no problem drinking, but the thing to remember is that this is often very finely ground up limestone - it won't hurt you, but it can put some people's digestive systems out of whack, so you get the poops (and think you've had bad water..) Generally I've found if it doesn't taste funny (like it has ground up chalk in it) it's fine and doesn't bug me. the water at the base of that glacier above did, OTOH, the water in the pics below was all fine for me:






And for the record, the water in the *first* picture above clogged three filters in four point campground, who all ended up "yogi-ing" a dose of pristine from me so they'd have water

the other thing to remember is it's usually not hard to find "less silty" water when the big creeks are running hard - just look for a little side feeder or spring or seep.
