Collect, filter, and store your water in the backcountry with the quick and convenient MSR Autoflow Gravity Filter. This field-cleanable filter lets gravity do the work and cleans nearly two liters of water per minute. The four-liter reservoir holds enough hydration for your whole group, and the adapter end piece fits onto most standard water bottles and reservoirs. It's field cleanable, too, so you can remove all the bacteria, protozoa, and sediment that's been filtered out and have a filter that's good as new in minutes.

The North Cascades have long been known as the North American Alps. Characterized by rugged beauty, this steep mountain range is filled with jagged peaks, deep valleys, cascading waterfalls and glaciers. North Cascades National Park Service Complex contains the heart of this mountainous region in three park units which are all managed as one and include North Cascades National Park, Ross Lake and Lake Chelan National Recreation Areas.
Badgers are animals of open country. Their oval burrows (ten inches across and four to six inches high) are familiar features of grasslands on sandy or loamy soils of the eastern plains or shrub country in mountain parks or western valleys.
