Hecate Strait

Hecate Strait and Pitt Island
Hecate Strait as delineated by BCGNIS, along with Queen Charlotte Sound and Dixon Entrance. Red dots indicate capes and points, gray text indicates island names. The international boundary between Canada and the United States follows Portland Canal to "Point B", thence to Cape Muzon. The "A-B Line" portion of the boundary is disputed.

Hecate Strait (; Haida language: K̲andaliig̲wii,[1] also siigaay which means simply "ocean") is a wide but shallow strait between the Haida Gwaii (formerly the Queen Charlotte Islands) and the mainland of British Columbia, Canada. It merges with Queen Charlotte Sound to the south and Dixon Entrance to the north. About 87 miles (140 km) wide at its southern end, Hecate Strait narrows in the north to about 30 miles (48 km)[2] It is about 160 miles (260 km) in length.[3]

According to the BCGNIS, the southern boundary of Hecate Strait is defined as a line running from the southernmost point of Price Island to Cape St James on Kunghit Island, the southernmost point of Haida Gwaii. The northern boundary is a line from Rose Point, the northeastern tip of Graham Island, to Hooper Point at the north end of Stephens Island off the mainland.[2]

Hecate Strait was named by Captain HecateHMS .[2]

History

Hecate Strait, because it is so shallow, is especially susceptible to storms and violent weather. The Haida crossed the Hecate Strait to the mainland to plunder coastal villages to take slaves and booty. Only the Haida knew the real nature of the Strait's workings, and so could not be followed by the tribes of the mainland. Hecate Strait, therefore, was one of the main defenses of the Haida people from attack.

Geology

During the last Ice Age, the seafloor in this area was a wide coastal plain stretching south to the Olympic Peninsula and including what is now Queen Charlotte Sound.[4]

Flora and fauna

The strait once contained strong salmon and halibut fisheries.

Hecate Strait is one of the few locations in the world with species from the Glass Sponge class of fauna. Regions with these sponge are currently protected from damage by commercial fishing.[5]

What is now Hecate Strait, the body of water that separates Haida Gwaii from the mainland, was for the most part dry land. Throughout this area of dry land, there were lakes and small rivers draining north and south to the Pacific Ocean. Soil samples from Hecate Strait indicate that many areas were habitable in the last ice age. After 10,000 years ago, the melting glaciers contributed to a rise in the sea level that resulted in a flooding of the Northwest Coast, temporarily creating beach lines high above today's high tide marks.".
