On Wilderness Atlas →

Petersburg Creek-Duncan Salt Chuck Wilderness begins about 2.6 miles away, and it is the closest of these.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

The cabin was originally built as an administrative site for Forest Service timber layout crews, but was converted to a recreation cabin in 1987. It sits back from the rocky eastern shore of Portage Bay in southeastern Alaska. The surrounding terrain is hilly along the east and flat and rolling south and west of the bay. Portage Mountain rises 3,577 feet in the background.

Recreation

There is excellent halibut fishing in the mouth of Portage Bay. Coho, pink salmon, steelhead and trout fishing are available in the nearby Portage Creek. The primitive Portage Mountain Loop Trail connects the cabin with Petersburg Lake Cabin and Salt Chuck East Cabin through Goose Cove, south of the bay. The trail is especially primitive over to Petersburg Lake and is seldom used due to the level of difficulty. Sections of the trail are flooded by beaver ponds.
