Tracy Arm-Fords Terror Wilderness contains and consists of two deep and narrow fjords: Tracy Arm and Endicott Arm. Both fjords are over 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

Access
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.

Deepwater Emergence

The deep passageways and thin continental shelf leads to unique connections between offshore and inshore waters. The colder water temperature, nutrient-rich upwelling, and strong currents allow for many species that live in deeper water to survive in the shallower waters.
