Wrangell Narrows
Name	Wrangell Narrows
Location	Alexander Archipelago, Southeast Alaska, United States
Type	Tidal channel
Length	35 mi (56 km)
Coordinates	56°12′N 132°23′W

Wrangell Narrows is a narrow, winding tidal channel separating Mitkof Island from Kupreanof Island in the Alexander Archipelago of Southeast Alaska. The channel lies near the city of Wrangell, Alaska and connects to Frederick Sound and Sumner Strait, forming part of the inland passage used by vessels transiting among the islands of the region. The Narrows is notable for its complex bathymetry, numerous shoals and reefs, and long history of indigenous use, exploration, and modern navigation.

Geography and Physical Characteristics

The Narrows threads through the Alexander Archipelago between Mitkof Island and Kupreanof Island, lying southeast of Prince of Wales Island and northwest of Zarembo Island and Stikine Strait. It extends roughly from Frederick Sound at its northeastern approach to Sumner Strait at its southwestern exit, skirting the town of Wrangell, Alaska near the mouth of the Stikine River. The channel’s bathymetry includes numerous shoals such as Neva Strait shoal and rocky outcrops near Petersburg, Alaska approaches, while tidal currents are influenced by the larger Pacific-Interior water exchange documented in studies around Southeast Alaska. The surrounding landscape is dominated by the temperate rainforests of the Tongass National Forest with glacially scoured fjords and islands formed during the Pleistocene.

Navigation and Maritime Significance

Wrangell Narrows forms part of the Alaska Marine Highway and the sheltered inland route preferred by many commercial and recreational vessels navigating between Juneau, Alaska and Ketchikan, Alaska. Historically charted during voyages by George Vancouver and later surveyors from the United States Coast and Geodetic Survey, the channel is marked by a sequence of daybeacons and range markers maintained by the United States Coast Guard. Marine traffic includes ferries operated by the Alaska Marine Highway System, towing vessels from companies like Crowley Maritime, fishing vessels licensed under North Pacific Fishery Management Council regulations, and cruise liners adjusting routes near Inside Passage. Pilotage and local knowledge are often employed by operators from ports such as Klawock, Alaska and Petersburg, Alaska to negotiate narrow turns, reefs, and tidal rips.

History and Human Use

Indigenous peoples of the region, including the Tlingit and Haida, used the waterways and islands for seasonal fisheries, trade, and travel long before European contact; oral histories and material culture preserved in sites tied to Tlingit culture record routes through island channels. Russian explorers and fur traders from Russian America mapped portions of the Alexander Archipelago during the late 18th and early 19th centuries, with figures associated to Russian-American Company activity visiting nearby posts. Following the Alaska Purchase and increased American maritime activity, communities such as Wrangell, Alaska and Kupreanof, Alaska developed as trading, fishing, and logging centers tied to enterprises like Alaska Steamship Company and later pulp and timber operations connected to the Alaska Pulp Corporation. The Narrows has supported timber transport, commercial salmon fisheries regulated by Alaska Department of Fish and Game, and regional commerce facilitated by the Alaska Marine Highway.

Ecology and Environment

The Narrows lies within the ecological matrix of the Tongass National Forest temperate rainforest and supports marine and coastal ecosystems central to Southeast Alaska biodiversity. Waters host populations of Pacific salmon species such as Chinook salmon, Coho salmon, and Sockeye salmon that migrate through the channel, supporting commercial and subsistence fisheries tied to communities like Kake, Alaska and Hoonah, Alaska. Marine mammals including Steller sea lion, harbor seal, and transient Orcinus orca populations use the broader Inside Passage, while seabirds such as glaucous-winged gull and pigeon guillemot frequent the shoreline. The intertidal zones and eelgrass beds near the mouth of the Stikine River provide nursery habitat influenced by freshwater inputs, glacial sediment, and nutrient fluxes studied by researchers from institutions including the University of Alaska Fairbanks and conservation organizations like The Nature Conservancy.

Infrastructure and Safety

Navigational safety in the Narrows is supported by aids to navigation maintained historically by the United States Lighthouse Service predecessors and currently by the United States Coast Guard, including daybeacons, buoys, and lighted ranges. Charting by the National Oceanic and Atmospheric Administration and hydrographic surveys inform pilotage for vessels operated by companies such as Alaska Marine Highway System and private ferry operators serving communities including Petersburg, Alaska and Klawock, Alaska. Search and rescue coordination is provided by Coast Guard sectors and local volunteer entities like municipal harbor authorities; maritime safety is further governed by regulations from the Federal Maritime Commission and applicable United States federal law statutes. Infrastructure on nearby islands includes small harbors, marinas, and logging docks once affiliated with regional operators and shipping lines.

Recreation and Tourism

Recreational use of the Narrows and adjacent waterways includes sportfishing for halibut and salmon, wildlife watching for species such as bald eagle and brown bear, and kayaking and small-boat cruising within routes popular among travelers on the Inside Passage. Tourism operators based in Wrangell, Alaska and neighboring ports offer guided excursions, lodge stays, and cultural tours highlighting Tlingit heritage and regional natural history; cruise lines calling on Alaska ports often reroute through nearby channels including Frederick Sound to view marine wildlife and glacial scenery. Outfitters affiliated with regional visitor bureaus coordinate activities during summer months when weather and marine conditions favor leisure navigation.
