If you stand atop Triple Divide Pass in Glacier National Park you'll be near a geographic rarity - a hydrological apex - where water flowing off the various sides of Triple Divide Peak empties into three separate oceans. Oh yea, the scenery is quite awesome as well: http://www.hikinginglacier.com..../triple-divide-pass.
Swiftcurrent Pass provides unbelievable views of the Many Glacier and Granite Park areas - one of the best hikes in Glacier National Park: http://www.hikinginglacier.com..../swiftcurrent-pass.h
The hike to Gunsight Lake provides one of the most magnificent views in Glacier National Park. The grassy meadow alongside Mirror Pond is framed by Mt. Jackson, Gunsight Mountain, Fusillade Mountain and Gunsight Pass: http://www.hikinginglacier.com/gunsight-lake.htm
