Glacier Bay
Glacier Bay National Park includes 16 tidewater glaciers: 12 actively calve icebergs into the bay. The show can be spectacular. As water undermines the ice fronts, great blocks of ice up to 200 feet high break loose and crash into the water. The Johns Hopkins Glacier calves such volumes of ice that it is seldom possible to approach its ice cliffs closer than about 2 miles.

The national park is an entire array of ecosystems. Lush pine forests and protected coves give way to beautiful saltwater beaches and jewel-like lakes. Glacier Bay is a living laboratory for observing the ebb and flow of glaciers and a chance to study life as it returns in the wake of retreating ice.
