Ugadaga Bay is part of Beaver Inlet, one of the large embayments on Unalaska Island in the Eastern Aleutians, about 6 miles (10 km) southeast of Dutch Harbor, Alaska.
The native Unangan people, including those who lived in the village of Biorka on nearby Sedanka Island, would put in at Ugadaga Bay with their kayaks for the overland trek to Unalaska village, a major trading center for otter and fox pelts. The Ugadaga portage is ancient and may have been used for more than 9,000 years.
The trail was also used by the U.S. military in the 1940s to bring supplies to a communication post in Ugadaga Bay. Anticipating an invasion by Japanese forces during World War II, the U.S. military deployed thousands of Rommel stakes near potential landing beaches. Rommel stakes, also known as screw pickets, were a choice defensive weapon used as supports for barbed wire. Many of the stakes remain and are considered a local hazard. The village of Biorka was abandoned after the war, but the trail is still used as a popular recreational hike. Read more here and here. Explore more of Ugadaga Bay and Beaver Inlet here:
