In addition, there is limited access to within 2 miles of the area by road from Yakutat. Much of the area is composed of rugged peaks, glaciers, and icefields which severely restrict access. There are numerous active glaciers above the ice carved fiords. The area is of great scientific interest for its record of recent catastrophic geological events, post glacial ecological succession, and the effects of frequent earthquakes. The area displays great scenic variety.
Vegetation ranges from heavily forested river channels to alpine meadows at higher elevations.
Situk Lake and the head waters of the Situk Wild and Scenic River Study Area are within the Wilderness. Mountain goats, wolves, brown and black bears, and numerous furbearers occupy much of the area. Harbor seals and sea lions utilize the major rivers and fiords. Shore birds, song birds, waterfowl and bald eagles are found in many parts of the Wilderness. Fisheries are fairly limited, with the exception of the lower reaches of Russell Fiord and the headwaters of the Ahrnklin.
