Tarr Inlet, Alaska 99826, USA
Margerie Glacier Around 1.6 kilometers wide, this hanging glacier has a dramatic 76-meter-high face. Big and beautiful, the river of frozen water flows 1.8 to 2.4 meters daily and very actively sheds icebergs. Those fragments contain compacted snow that fell 75 to 200 years ago, before half the states had even joined America. Presiding over the bay’s extreme northwestern end—perpendicular to the Grand Pacific Glacier—Margerie Glacier serves as the turning point for many cruise ships.
