Impassable Northwest Passage Open For First Time In History 528
An anonymous reader writes "The Northwest Passage, a normally ice-locked shortcut between Europe and Asia, is now passable for the first time in recorded history reports the European Space Agency. Leif Toudal Pedersen from the Danish National Space Centre said in the article: 'We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.'"

Not in any great hurry ; in theory, the opening of the Arctic Ocean could make development and/ or extraction of minerals somewhat cheaper in the immediate coastal regions. But once you're more than a few tens of miles from the coast, then you're going to find that the costs of building rail lines or pipelines (depending on if you're talking about minerals or oil) gets up to the level where it's just as cheap in the long run to go overland with rail. And that's not going to be a quick option. Then again, building port facilities isn't quick either, particularly if you've got no port to bring the building materials for building your port.

Of course, you could be referring to the 1630s as several attempts were made after this to find this passage that did not exist. Perhaps (but surely not) you're conflating the (prior lack of) existence of the Northwest Passage with the satellite record — which only stretches back about 30 years or so. Still, we know that the Northwest Passage has not been passable for well over 400 years.

Basically, the Haida band, who are the indigenous First Nation of Haida Gwaii (the archipelago which you non-PC foreigners are probably more familar with as "the Queen Charlotte Islands") display such a number of cultural similarities to the Norsemen that many reasonable people find it less of a stretch to presume that there was contact between them than to assume a remarkable cascade of coincidences. Let us take an example, boat design.
""Yakutat," or "Northern-style" canoes include a variety of design forms, including a characteristic curve and swelling near the bow. The prow of the canoe gracefully curves up from the water and can be adorned by elaborate carvings."
http://www.amnh.org/exhibitions/expeditions/treasure_fossil/Treasures/Haida_Canoe/canoe.gif [amnh.org]
Now, contrary to the learned discourse above, these are not actually characteristic of Haida design. There is one other culture that designed its ocean-going vessels with those same "characteristic" traits. Care to guess what that culture was?
http://www.geocities.com/dragar.geo/WSP/Pix/longship.gif [geocities.com]
Those are just the first two images Google search came up with for each; if you look into it further, you'll find that the similarities are more striking than those two make apparent. Striking enough that when Haida/Tlingit take their canoes on cultural exchanges to Europe, they constantly get questions along the lines of "why did you make a longship out of a single tree trunk and paint it funny?", as Europeans just assume that the design is a conscious imitation of the Norse, not their own.
Also, the Haida are physiologically distinct, rather dramatically so in fact, from every other American aboriginal culture; they are taller, whiter, grow facial hair, and produce significant quantities of brunettes and redheads.
"Marchand also described the Haidas of Queen Charlotte Islands whom he visited in 1791. He found them not differing materially in stature from Europeans, better proportioned and better formed than the Sitkans and without the gloomy and wild look of the latter. Their color he found did not differ from that of Frenchmen, and several were less swarthy "than the inhabitants of our country places' (Edward L. Keithahn, MONUMENTS IN CEDAR: The Authentic Story of the Totem Pole, Bonanza books, New York 1971:19-23, emphases supplied)."
This is not consistent with Haida mixing with Asian genetic pools, or any other Western North American genetic pool, or hell any other race bordering the entire Pacific for that matter. On the other hand, this is remarkably suggestive of significant admixture with a Scandinavian genetic pool, yes?
