Drinking straight from crystalline mountain streams is nice in principle, but a lot less awesome when you end up running for the bushes every five minutes for the rest of the trip. There are plenty of ways to help save yourself from waterborne bummers, but none that are as effective, easy to use, and reliable as the MSR Guardian Purifier System. Developed for, and in conjunction with, the US military, the Guardian uses new Hollow Fiber technology to filter out just about everything (protozoa, bacteria, particulate, and even viruses), so you can sip fresh, clean water without first checking that you packed extra TP. The Guardian has an easy pump-action design that can filter up to 2. 5 liters per minute, and an ingenious self-cleaning design--10% of the water from every stroke flushes contaminants from the filter, so it never gets clogged or becomes less effective. The wastewater is discharged through a tube that runs parallel to the intake, so it empties easily back into the water source. MSR also included a water-bottle adapter for easy fill-ups, and a cartridge life indicator that lets you know when it's time to switch (although the included filter is good for at least 10,000L, so it might be a while before it's that time).

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
