Tracy Arm (Twin Sawyer Glaciers), AK Overview
Tracy Arm is a fjord in Alaska near Juneau. Tracy Arm-Fords Terror Wilderness contains 653,179 acres (2,643.32 km) and consists of two deep and narrow fjords: Tracy Arm and Endicott Arm. Both fjords are over 30 miles (48 km) long and one-fifth of their area is covered in ice. During the summer, the fjords have considerable floating ice ranging from hand-sized to pieces as large as a three-story building. During the most recent glaciated period, both fjords were filled with active glaciers.
The most common access is by boat using Stephens Passage and entering Holkham Bay and Tracy and Endicott Arms. Float planes from Juneau and Petersburg are also used as a means of access. Large tour vessels and smaller commercial cruise boats frequently use Tracy Arm as a tour destination or as a stop along their normal tour routes.
