Which glacier in Alaska and Yukon is named after Gardiner Hubbard?

Hubbard Glacier, in Alaska and Yukon, is named after Gardiner Hubbard.

The glacier lies in Wrangell–St. Elias National Park and Preserve in eastern Alaska and continues into Kluane National Park and Reserve in Yukon, Canada. Its longest source extends roughly 122 kilometers from the snout, making it one of the major ice systems of the region.

Hubbard Glacier is a tidewater glacier that has generally advanced for about a century, an unusual contrast to the retreat of many glaciers. In 1986, it surged forward and blocked the outlet of Russell Fjord, creating Russell Lake before the natural ice dam failed. A similar closure occurred in 2002. Gardiner Hubbard was an American businessman and the founder and first president of the National Geographic Society, which helps explain why his name appears in geographic naming.
