Oregon Earthquakes and Tsunamis

Source: Byram 2007.

Every few centuries, on average, the Northwest Coast gets shocked by a massive mega-thrust earthquake, on the order of 8 to 9 on the Richter scale.  On occasion, these produce a devastating tsunami wave.  It wouldn’t be surprising then if such disruptive events featured in aboriginal oral histories and also in the archaeological record itself.  There is a growing body of research on this topic which I am not planning on reviewing at this time, but a nicely focused starting point is a series of papers in the Oregon Historical Quarterly, available online.

Raven de La Perouse

My recent post on the 1786 visit by La Perouse to Tsunami-prone Lituya Bay, Alaska sent me scurrying to download the massive ethnography by Frederica de Laguna entitled Under Mount St. Elia Under Mount Saint Elias: The History and Culture of the Yakutat Tlingit.  As expected, there is a rich oral history of waves in this bay.  From Volume 1, page 94, she says

Emmons (1911, p. 295) recorded Indian beliefs about the dangers of Lituya Bay, caused by:
“… a monster of the deep who dwells in the ocean caverns near the entrance. He is known as Kan Lituya, ‘the Man of Lituya’ [qa htu ‘a?]. He resents any approach to his domain, and all of those whom he destroys become his slaves, and take the form of bears, and from their watch towers on the lofty mountains of the Mt Fairweather range they herald the approach of canoes, and with their master they grasp the surface water and shake it as if it were a sheet, causing tidal waves to rise and engulf the unwary.

De Laguna then continues to discuss an extraordinary wooden smoking pipe, illustrated above:

“This legend of Lituya is illustrated by a carved wooden pipe (fig. 50) [pi. 123], of splendid proportions, which was obtained in 1888 from the chief of the Tuck-tane-ton family of the Hoon-ah Kow [DAqdentan sib of Hoonah], who claimed this bay as his hereditary sea-otter hunting ground. It was used only upon occasions of particular ceremony—when the clan assembled to honor the dead, or to deliberate upon some important question of policy. At one end is shown a froglike figure with eyes of haliotis shell, which represents the Spirit of Lituya [possibly the Frog crest of the sib?], at the other end the bear slave sitting up on his haunches. Between them they hold the entrance of the bay, and the two brass-covered ridges are the tidal waves they have raised, underneath which, cut out of brass, is a canoe with two occupants, that has been engulfed. [Author’s note: This illustration was furnished through the courtesy of Mr George G. Heye, in whose collection the pipe now is.”]

One thng leading to another, I thought I would look into whether the Tlingit story of La Perouse’s visit had been passed on.  As it turns out, the early ethnographer G.T. Emmons records an account given by a Tlingit chief one hundred years after the visit of La Perouse to Lituya Bay.  This gives an indigenous perspective on what must have been an extraordinary series of events for both parties.  This account is well worth reading, so I am reproducing a portion of Emmons (1911) rendering below:

“In 1886, one hundred years after [the vist of la Perouse], Cowee, the principal chief of the Auk qwan of the Tlingit people, living at Sinta-ka- heenee, on Gastineaux Channel, told me the story of the first meeting of his ancestors with the white man, in Lituya Bay, where two boats of the strangers were upset and many of them were drowned. This narrative had been handed down by word of mouth for a century. These people possess no records nor had the chief, who spoke no word of our tongue, ever heard of La Perouse from outside sources; so we can here authenticate by an exact date a most interesting piece of native history in detail, the truth of which is substantiated by the fact that La Perouse was the only one of the early navigators to visit this locality in a large ship and by the attending loss of life in the destruction of his two boats.  Continue reading

Destruction of Kwalate Village

Yesterday’s post about Marianne Nicolson’s powerful pictograph in Kingcome Inlet and the post from a few days ago about the enormous Tsunami in Lituya Bay got me thinking again about recent work in Knight Inlet on the central B.C. Coast (map).

A recent project by a team of geomorphologists and an archaeologist, UVic’s own Duncan McLaren, investigated oral historical accounts about Kwalate Village of the A’wa’etlala and Da’naxda’xw peoples, of the Kwakwaka’wakw First Nations.  The accounts state that a landslide in Knight Inlet triggered a local Tsunami which swept this village away. This account is known anthropologically through a number of sources, including Franz Boas (1910, Kwakiutl Tales):

“About three generations ago, or possibly at an earlier date, a large portion of the mountain opposite Kwalate Point slid into the inlet causing a huge tidal wave which wiped out all of the inhabitants of the village opposite…and the vast slide is noticeable today”.

Of course, the story of the destruction of Kwalate is still told and the dead, unknown in number but perhaps up to one hundred, are still mourned and memorialized in the surrounding communities.  While it is not necessary, or even desirable or possible, for archaeology to confirm oral historical accounts, when that happens it can be of interest to archaeologists and First Nations people alike.

La Perouse at Port des Francais (Lituya Bay)

Most readers will be very familiar with Captains Vancouver and Cook and some of the other early European explorers of the Northwest Coast.  Less familiar is Jean-François de Galaup, Comte de La Pérouse, (1741-1788), who embarked on a world journey of exploration in 1785:

The French decided to mount a scientific and exploration voyage to rival that of Captain James Cook. Two ships, the Boussole and the Astrolabe, under La Perouse’s command left France in August 1785. They spent the summer of 1786 off the coasts of Alaska looking for a northwest passage then sailed down the west coast of North America in August and September 1786.

One of their most memorable and tragic periods was the time they spent in Lituya Bay, Alaska, which they called Port des Francais (map).

Their mapping and illustration of Tlingit life are not unknown but also not that easy to find.  I recently came across an interesting site which has the best web presentation of these materials (actually reproduced from a 1798 British edition) I have seen: the images are highly zoomable, and the zoom is fast and crisp and smooth.  Linking to specific images is possible and the links don’t break.  With a little bit of effort, you can download the images (hint: “view source” of the page and search for ‘Size4″).  So zoom right in and see the details of pictures such as this one of a fish camp (are those halibut drying, or Pacific cod?), or this one of both a fine Tlingit dugout, and the construction of a skin vessel, with its seal skin hull removed and placed to one side.  The chart made by La Perouse is here and full of detail (again, these are English re-engravings of the originals).

While spending  time in Lituya Bay, tragedy befell the expedition. From here, an account of La Perouse’s time in Port des Francais:

1786 July Port des Francais / Lituya Bay

The next day, the narrow entrance to an inlet was located to the east of Cape Fairweather. De Pierrevert, from the Boussole, and Flassan, from the Astrolabe, were dispatched in small boats to investigate the inlet. Their favourable reports encouraged a somewhat reluctant La Pérouse to take the ships in. Their first approach was unsuccessful and they tacked offshore through the night before the tide carried them in the next morning. Even then, it was a precarious passage and the ships both nearly were driven onto rocks. They anchored just inside the entrance but La Pérouse was not happy with this spot, it having a shallow, rocky bottom. He sent men off to a find safer anchorage. D’Escures found a better location behind the large island in the inlet and the two ships transferred there. It was 3 July 1786.
