Glacier Bay is covered with 1,375 square miles (3,560 km2) of glaciers which accounts for 27% of the Park area with most glaciers originating in mountains with elevation range of 8,000–15,000 feet (2,400–4,600 m). There are over 50 named glaciers (both tidewater and terrestrial glaciers); 10 tide water…

After a period of quiescence, an intense eruption took place at Okmok in 43 BCE. A rhyodacitic eruption column rose over the volcano from a vent in its northern part. Pumice lapilli fell out from the eruption column. The fallout was emplaced in three distinct units, with a brief break between the first two…

Renamed "Skira", the island was used as the setting for the Codemasters video game Operation Flashpoint: Dragon Rising. The fictionalized version of the island is relocated closer to Russia and China, but the island's topography is replicated almost exactly.

Modern Mount Wrangell, built upon the remnants of a mid-Pleistocene volcano, has an eruptive history spanning from 750,000 years ago to minor phreatic eruptions in 1884. The shield volcano features an ice-filled caldera 2.5 by 3.7 miles (4 by 6 km) in diameter at the top of Wrangell's broad summit. The caldera…

Mount Blackburn is a large, dramatic peak, with great local relief and independence from higher peaks. Its west face drops over 11,000 ft (3,350 m) to the Kuskulana Glacier in less than 4 horizontal miles (6.4 km). Its other faces drop 8,000–10,000 ft (2,440–3,050 m), all in less than 8 miles (13 km). The…

Mount Sanford was first climbed on July 21, 1938 by noted mountaineers Terris Moore and Bradford Washburn, via the still-standard North Ramp route up the Sheep Glacier. This route "offers little technical difficulty" and "is a glacier hike all the way to the summit" but is still a serious mountaineering…

Umnak, the third largest of the Aleutian Islands after Unimak and Unalaska, lies in the Fox Islands of the Aleutian Islands of the Bering Sea, to the southwest of the larger island of Unalaska. It is approximately 70–72 miles (113–116 km) in length (117 kilometres (73 mi)) and 16 miles (26 km) wide on…

The same topography that leads to the heavy tidal currents also created the tsunami with the highest runup against a hillside in recorded history. On the night of July 9, 1958, an earthquake caused a landslide in the Gilbert Inlet at the head of the bay, generating a massive megatsunami which had sufficient…

It was for this latter reason that engineers chose Eagle Summit as the route to build the Steese Highway, which connects Fairbanks, Alaska to the Yukon River at Circle. In 1927, just 11 years after Stuck became one of the first Americans to navigate Eagle Summit on dog sled, the highway was completed and road…
