Ogilvie River/Engineer Creek confluence (aerial)
Canada

A 46m aerial view showing the stark contrast of the clear Ogilvie River merging w/ the iron-rusted Engineer Creek along the Dempster Highway north of Tombstone Territorial Park, Yukon.  Engineer Creek as well as nearby Red Creek easily resemble a massive spill of acid mine drainage however the source is actually natural.  The creek gets its colour from iron deposits that have broken to the surface. Specifically, the water becomes jet black after picking up minerals from an exposed seam of black shale, and progressively turns red as it meanders downstream.

 

The water may not necessarily kill anyone who drinks it, but it fails several basic Canadian Environmental Quality Guidelines. Animals have been seen to avoid Engineer & Red Creek, and the rocks along its path are dyed a deep reddish hue by the high-water mark of the contaminated creek.  A chemical analysis of the water revealed levels of iron, nickel, and zinc at more than 10 times what geoscientists considered a “normal” Yukon concentration.

 

Engineer (& Red Creek) have presumably been this way since woolly mammoths walked the area. The Yukon is located in Beringia, one of the few areas of North America not to have been carved up by glaciers in the last ice age, so it remains a unique time capsule of how the continent looked before human settlement.

More About Canada

The capital of Canada is Ottawa, in the province of Ontario. There are offically ten provinces and three territories in Canada, which is the second largest country in the world in terms of land area.While politically and legally an independant nation, the titular head of state for Canada is still Queen Elizabeth.On the east end of Canada, you have Montreal as the bastion of activity. Montreal is famous for two things, VICE magazine and the Montreal Jazz Festival. One is the bible of hipster life (disposable, of course) and the other is a world-famous event that draws more than two million people every summer. Quebec is a French speaking province that has almost seceded from Canada on several occasions, by the way..When you think of Canada, you think of . . . snow, right?But not on the West Coast. In Vancouver, it rains. And you'll find more of the population speaking Mandarin than French (but also Punjabi, Tagalog, Korean, Farsi, German, and much more).Like the other big cities in Canada, Vancouver is vividly multicultural and Vancouverites are very, very serious about their coffee.Your standard Vancouverite can be found attired head-to-toe in Lululemon gear, mainlining Cafe Artigiano Americanos (spot the irony for ten points).But here's a Vancouver secret only the coolest kids know: the best sandwiches in the city aren't found downtown. Actually, they're hidden in Edgemont Village at the foot of Grouse Mountain on the North Shore."It's actually worth coming to Canada for these sandwiches alone." -- Michelle Superle, VancouverText by Steve Smith.
