Petersburg Creek-Duncan Salt Chuck Wilderness
The Petersburg Creek-Duncan Salt Chuck Wilderness is made up of two watersheds divided by the alpine covered peaks of Portage Mountain. On the east side of the Wilderness, Petersburg Creek spills down a U-shaped glacier-cut valley with mountain peaks overlooking the valley. The mountains reach their highest point at 3,577 feet and slope down to the sea-level grass flats of the Petersburg Creek estuary, a popular place for sheltered sea kayak day trips beginning in Petersburg. The creek is known for its salmon and trout, as well as for the uplands wildlife of black bears, wolves, black-tail deer and moose. A 6.5-mile rugged trail connects Petersburg Lake with a saltwater trailhead four miles west of Petersburg.
