Icy Bay is on the Gulf of Alaska coast about 66 miles (106 km) northwest of Yakutat and lies within Wrangell-St. Elias National Park and Preserve. The area was first explored on June 4, 1794 by Joseph Whidbey, a sailing master in the Royal Navy who served on the Vancouver Expedition. The bay was then blocked by the giant tidewater Malaspina Glacier that calved icebergs directly into the Gulf of Alaska. The bay was described as an indentation of the glacier face and named by Captain George Vancouver but not shown on expedition charts. The present Icy Bay was uncovered by the retreat of the Guyot, Yahtse, and Tyndall Glaciers that stream from the St. Elias Mountains, the highest coastal mountain range on Earth. This century-long glacial retreat has opened a multi-armed bay more than 30 miles long (48 km). Read more here and here.
