LeConte Glacier is marked by granite peak formations such as Devis Thumb in the background in the Stikine Icefield seen in an aerial view.
It is one of the few remnants of the once-vast ice sheets that covered much of North America during the Pleistocene, or Ice Age, the epoch lasting from 2.5 million to 11,700 years ago. LeConte covers 2,900 square miles along the crest of the Coastal Mountains that separate Canada and the U.S., extending 120 miles from the Whiting River to the Stikine River in Alaska’s Tongass National Forest.
There are over 100,000 glaciers in Alaska and LeConte is the southernmost active tidewater glacier in the northern hemisphere.
