While most of the world’s glaciers are receding, North America’s largest tidewater glacier is advancing. At 76 miles long and 7 miles wide, Hubbard Glacier presents a majestic sight for passengers cruising across Yakutat Bay on the Alaskan panhandle. The glacier calves frequently, meaning that large chunks of ice break off from its face and plunge into the water below, creating icebergs. In addition to witnessing this spectacle of nature, keen eyes also can catch glimpses of the area’s wildlife, which includes harbor seals, orcas, and humpback whales.
