South Kruzof

South Kruzof is a 55,193-acre Inventoried Roadless Area on the southern half of Kruzof Island in the Alexander Archipelago of Southeast Alaska, administered by the Tongass National Forest. The area centers on Mount Edgecumbe, a stratovolcano rising more than 3,200 feet from the island's interior, with associated landforms including Crater Ridge, Shell Mountain, and Montaña de San Jacinto. The shoreline runs from Cape Edgecumbe and Sitka Point south along Beaver Point, Trubitsin Point, Kamenoi Point, Inner Point, Point Brown, Engano Point, and Escape Cape. Freshwater drains through short, steep catchments to Shelikof Bay, Crab Bay, and Neva Bay; Freds Creek empties to the eastern shore opposite Sitka.

South Kruzof lies within the Coastal Temperate Rainforest of Southeast Alaska. Sitka spruce (Picea sitchensis) and western hemlock (Tsuga heterophylla) form the closed canopy on the lower slopes, with mountain hemlock (Tsuga mertensiana) and Alaska-cedar (Callitropsis nootkatensis) common at higher elevations and lodgepole pine (Pinus contorta) on the muskegs. The understory carries devil's club (Oplopanax horridus), salmonberry (Rubus spectabilis), and Alaska blueberry (Vaccinium alaskaense). Coastal dune and beach communities ring the shoreline with American dunegrass (Leymus mollis), beach pea (Lathyrus japonicus), and beachhead iris (Iris setosa). Subalpine meadows on the upper slopes of Mount Edgecumbe support Nootka lupine (Lupinus nootkatensis) and western moss-heather (Cassiope mertensiana).

The forest, shoreline, and pelagic habitats of South Kruzof support a wide assemblage of marine birds, mammals, and fish. Tufted Puffin (Fratercula cirrhata), Horned Puffin (Fratercula corniculata), Rhinoceros Auklet (Cerorhinca monocerata), and Common Murre (Uria aalge) nest on offshore islets and inshore cliffs facing the Pacific. Marbled Murrelet (Brachyramphus marmoratus), assessed by the IUCN as Endangered, depends on the old-growth canopy for nesting and feeds offshore. Bald Eagle (Haliaeetus leucocephalus) and Black Oystercatcher (Haematopus bachmani) occupy the shoreline, while Black Turnstone (Arenaria melanocephala), Surfbird (Calidris virgata), and migrating Sanderling and Dunlin use the wave-cut intertidal flats. Sea Otter (Enhydra lutris), assessed by the IUCN as Endangered, raft along kelp lines in Shelikof Bay and Sitka Sound, while Steller Sea Lion (Eumetopias jubatus, IUCN Vulnerable) haul out on outer rocks. Brown Bear (Ursus arctos) and Mule Deer (Odocoileus hemionus) range through the interior forest, and salmon-bearing streams support spawning Chinook Salmon (Oncorhynchus tshawytscha). Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

The Mt. Edgecumbe Trail (FS 31520) runs 6.6 miles from Fred's Creek on the eastern shore to the volcano's crater rim, climbing more than 3,000 feet through muskeg, hemlock-spruce forest, and stunted alpine spruce before opening onto the bare pumice and rhyolite of the summit crater. From the rim the view extends across Sitka Sound to the city of Sitka and out to St. Lazaria Island on the open Pacific. Open beaches at Shelikof Bay carry the sound of surf against the outer coast, while the shorter Port Mary Trail (1.1 miles) offers an accessible walk on the eastern shore.

The lands of South Kruzof, on Kruzof Island just west of Sitka, lie within the traditional territory of the Sheet'ká Kwáan, the Tlingit people of the Sitka area, who occupied the western half of Baranof Island, the greater portion of Chichagof Island, and smaller islands seaward [1]. Mount Edgecumbe, the dominant landmark at the southern end of Kruzof Island, is known in Tlingit as Lʼúx, meaning "to flash or blink," a reference to its eruptive past [6][2]. Starting more than 3,000 years ago the Sitka Tlingit established a seasonal round centered on salmon fishing camps along streams throughout Shee Atiká, using trolling, basket-style traps, gaffs, spears, leisters, and stone or wood stake weirs to harvest salmon, which they cured at summer encampments alongside berries and other gathered plants [1].

After the Russian American Company was formed in 1799, the Kiks.ádi clan of Sitka came into protracted conflict with Russian forces seeking to secure a fur-trading post on Baranof Island [1]. On June 15, 1802, Kiks.ádi warriors destroyed the Russian Archangel Saint Michael's Redoubt at Old Sitka [1]. In September 1804 the Russians returned with 120 Russian-American Company employees and 800 Aleut allies; the Kiks.ádi defended the fortified village Shis'g'i Noow ("Green Wood Fort") for five days before withdrawing inland over Baranof Island's rugged mountains [1][7]. The Russians built Novo-Arkhangelsk on the captured site, retaining control until Alaska was transferred to the United States in 1867 [1]. By 1909, nearly all of the commercial timber in Southeast Alaska was incorporated into the Tongass National Forest, with regional harvest then averaging about 15 million board feet annually [3].

Federal protection of the Alexander Archipelago islands began on August 20, 1902, when President Theodore Roosevelt established the Alexander Archipelago Forest Reserve by presidential proclamation [4]. The Tongass National Forest was created by a separate proclamation on September 10, 1907, and on July 1, 1908, the two units were consolidated into a single Tongass National Forest with a total area of 6,756,362 acres [4]. A further proclamation on February 16, 1909, added 8,724,000 acres to the Tongass, bringing the great majority of forested Alexander Archipelago islands — including Kruzof — under Forest Service administration [4]. Industrial-scale logging on the Tongass began in 1951 with the signing of a fifty-year Forest Service timber contract, and a second long-term contract was signed in October 1957, committing 5.25 billion board feet of timber over fifty years from a sale area that included Baranof Island and portions of Chichagof Island [3]. In 1956 the newly formed Alaska Pulp Corporation acquired the site at Sawmill Creek near Sitka, and in November 1959 the company's pulp mill began producing wood fiber from Tongass National Forest timber [5][3]. The Alaska Pulp Corporation suspended operations at the Sitka pulp mill at the end of September 1993, and its long-term contract was terminated by the Forest Service in April 1994 [3]. South Kruzof, a 55,193-acre Inventoried Roadless Area within the Sitka Ranger District and Sitka County, is protected today under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

• Marbled Murrelet Old-Growth Nesting Habitat: South Kruzof's 55,193 acres of contiguous Coastal Temperate Rainforest retain the large-diameter Sitka spruce and western hemlock canopy that Marbled Murrelet (IUCN Endangered) requires for nesting. Without internal roads, the area's interior-forest microclimate and intact canopy extend continuously from shoreline up onto Mount Edgecumbe, preserving the structural conditions on which this seabird depends. The roadless condition is the principal mechanism keeping that nesting habitat unfragmented at a scale relevant to the species.

• Cold-Water Stream Integrity: The short, steep streams draining the area's interior — including Freds Creek and the unnamed drainages reaching Shelikof Bay, Crab Bay, and Neva Bay — flow off forested slopes directly to tidewater, with continuous riparian canopy maintaining cold water and stable gravel substrate. In the absence of road crossings these streams retain natural sediment regimes and continuous riparian buffers, conditions Chinook Salmon (Oncorhynchus tshawytscha) and other Pacific salmonids depend on for spawning and rearing.

• Forest–Intertidal–Marine Connectivity: The shoreline of South Kruzof joins forest, freshwater, intertidal, and pelagic habitats in an unbroken gradient. The kelp shallows along the outer capes support IUCN Endangered Sea Otter, the rocky outer islets host Steller Sea Lion haul-outs, and Pinto Abalone (IUCN Endangered) occupies the rocky subtidal zone. The roadless condition preserves the freshwater, sediment, and woody-debris inputs from forested headwaters that sustain these nearshore communities.

Potential Effects of Road Construction

• Sedimentation and Spawning Habitat Loss: Road construction on the steep, wet hillslopes typical of Kruzof Island would expose cut-and-fill slopes that erode chronically into adjacent drainages. Sediment delivered to spawning gravels suffocates salmonid eggs and reduces invertebrate productivity in the cold-water streams that drain to Shelikof Bay and Sitka Sound. Once installed, road-prism erosion continues for the operational life of the road, and recovery of pre-disturbance gravel structure can take decades after a road is decommissioned.

• Canopy Fragmentation and Marbled Murrelet Habitat Loss: Building roads through the unfragmented forest of South Kruzof would convert closed-canopy interior habitat — the nesting stratum on which Marbled Murrelet depends — into a network of edge zones, increasing solar exposure, wind-throw, and invasive-plant establishment. The interior-forest microclimate that sustains the large-tree canopy does not re-form once it is broken, and the resulting edges propagate further degradation into adjacent stands, reducing habitat value across far more forest than is physically cleared by the road.

• Disruption of Forest–Marine Linkages: Road construction near the shoreline would alter the freshwater, sediment, and woody-debris inputs that connect forested headwaters to nearshore marine habitats. Culverts replace natural channels, hydrologic timing shifts, and disturbed corridors carry pollutants and invasive species into intertidal and subtidal zones. These changes affect the kelp, eelgrass, and rocky subtidal communities on which Sea Otter, Steller Sea Lion, and Pinto Abalone depend.

South Kruzof, a 55,193-acre Inventoried Roadless Area on the southern half of Kruzof Island, lies a short boat ride west of Sitka and offers a mix of formal trail and dispersed water-accessed recreation. Access is by boat across Sitka Sound — most parties land at Fred's Creek on the eastern shore — or by chartered floatplane.

Hiking. The Mt. Edgecumbe Trail (FS 31520) is the area's signature route, running 6.6 miles one-way from Fred's Creek to the rim of the volcano's summit crater, with an elevation gain of more than 3,000 feet. The route climbs through muskeg, mixed hemlock-spruce forest, and stunted alpine vegetation before opening onto bare pumice and rhyolite at the top. The Mt. Edgecumbe Shelter Spur (FS 31520A, 0.1 miles) reaches a backcountry shelter near the upper trail. The Port Mary Trail (FS 31482, 1.1 miles) offers a shorter walk on the eastern shore.

Sea Kayaking and Small-Boat Travel. The long, indented shoreline of South Kruzof — Cape Edgecumbe, Sitka Point, Beaver Point, Trubitsin Point, Kamenoi Point, Inner Point, Point Brown, Engano Point, and Escape Cape — offers paddlers protected coves backed by open Pacific exposures. Crossings between the eastern shore and Sitka are exposed to the wind and chop of Sitka Sound. Shelikof Bay on the western coast carries long open beaches that draw outer-coast paddlers willing to manage surf landings and dispersed camping above the wrack line.

Wildlife Viewing and Birding. Marine birds dominate the local roster: Tufted Puffin (Fratercula cirrhata), Horned Puffin (Fratercula corniculata), Rhinoceros Auklet (Cerorhinca monocerata), Common Murre (Uria aalge), Black-legged Kittiwake (Rissa tridactyla), and Pelagic Cormorant (Urile pelagicus) occupy nearshore cliffs and offshore islets, and the nearby Alaska Maritime NWR–St. Lazaria Island eBird hotspot has logged 142 species across more than 500 checklists. Shorebirds — Black Turnstone, Surfbird, Sanderling, Dunlin, and Ruddy Turnstone — pass through the intertidal flats during migration. Sea Otter and Steller Sea Lion are routinely seen from the water; Humpback Whale (Megaptera novaeangliae) and Orca (Orcinus orca) work the deeper waters of Sitka Sound.

Hunting. Brown Bear (Ursus arctos), Mule Deer (Odocoileus hemionus, the Sitka black-tailed deer), and waterfowl support hunting opportunities regulated by the Alaska Department of Fish and Game. Hunters should consult the current Game Management Unit regulations and reporting requirements before traveling and must arrange for boat- or air-supported pack-out.

Fishing. Saltwater angling in Sitka Sound, Shelikof Bay, and the bays along the outer coast targets Pacific Halibut (Hippoglossus stenolepis), Lingcod (Ophiodon elongatus), and a rockfish complex including Yelloweye Rockfish (Sebastes ruberrimus), Black Rockfish (Sebastes melanops), and Copper Rockfish (Sebastes caurinus). Regulations and seasons are set by ADF&G for the relevant statistical areas. Freshwater fishing is limited by the short course of the area's streams; stream-mouth zones at Freds Creek can be productive when salmon are running.

Photography. Cape Edgecumbe, Crater Ridge, and the rim of Mount Edgecumbe offer long sightlines across Sitka Sound to the eastern islands and out over the Pacific. Coastal-cliff and intertidal photography at Sitka Point and along Shelikof Bay reveals the wave-cut shoreline, kelp beds, and offshore stack rocks that frame the outer coast.

Every activity above depends on the roadless condition of South Kruzof's interior. The maintained trail to Mt. Edgecumbe, the dispersed shoreline travel, and the unfragmented forest backing the kelp shallows and offshore islets all turn on the absence of inland roads. Visitors should be prepared for full remoteness off the trail, no cell service, and rapid weather changes.
