Tracy's Arm Fjord

Tracy Arm is a fjord in the U.S. state of Alaska near Juneau. It is named after the Secretary of the Navy Benjamin Franklin Tracy. It is located about 45 miles south of Juneau and 70 miles north of Petersburg, Alaska, off of Holkham Bay and adjacent to Stephens Passage within the Tongass National Forest. Tracy Arm is the heart of the Tracy Arm-Fords Terror Wilderness, designated by the United States Congress in 1990

Tracy Arm-Fords Terror Wilderness contains 653,179 acres and consists of two deep and narrow fjords: Tracy Arm and Endicott Arm. Both fjords are over 30 miles 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.
