Peril Strait or Háat Ishkáak is a strait in the Alexander Archipelago in southeastern Alaska. It is between Chichagof Island to its north and Baranof Island[1] and Catherine Island to its south. The strait is 80 km (50 mi) long and reaches from Salisbury Sound on the west to the Chatham Strait on the east.[1] It is entirely within the limits of the City and Borough of Sitka.
When a Tlingit canoe party was going through the tide was going against them and they had to stop and camp there until the tide was right to go through. Háat means tide, Ishkáak means to sit down; eel'é is also referred to where the tide goes in and out really fast.
The strait was named Proliv Pogibshy by Russians because of a fatal incident during a fur seal hunting expedition led by Alexander Baranof in 1799. According to V. F. Lisianski, Baranof employed Native Aleut hunters, ate poisonous shellfish from the strait, which resulted in approximately one hundred and fifty deaths.[1][2] Beyond the strait are the points Poison Cove and Deadman's Reach, also named for the incident. Peril Strait is the United States Coast and Geodetic Survey translation of Proliv Pogibshiy.[2]
As the strait runs between two large bodies of water (Chatham Strait and Salisbury Sound/Pacific Ocean), the tidal currents at Sergius and Kakul Narrows pose a danger to large vessels navigating the body of water.[1] With the exception of its fast ferries, the Alaska Marine Highway System only runs its mainline vessels through Peril Strait at slack tide.
On May 10, 2004, the AMHS vessel M/V LeConte grounded on Cozian Reef in Peril Strait. There were no major injuries, and after an extensive salvage process, the LeConte was escorted to Ketchikan for successful repairs. The cause of the grounding was determined to be operator error, not tidal currents.
The Fairway Island Light, located on the eastern entrance to Peril Strait, was an important aid-to-navigation in the early 20th century.
