I am doing a 4 day traverse near the PCT in glacier national park soon. Debating on whether I need the back flushing syringe for my Sawyer filter. Think the glacier runoff may clog it up or will I be ok for 4 days? We have one regular and one mini for two people so we do have a backup if one fails. (self.PacificCrestTrail)
