Smoking hills from the air northwest territories


The Smoking Hills are located on the east coast of Cape Bathurst in Canada's Northwest Territories, next to the Arctic Ocean and a small group of lakes. The cliffs were named by explorer John Franklin, who discovered them on his 1826 expeditions. They contain strata of hydrocarbons (oil shales), which have been burning continuously for centuries.

The fires result from autoignition of sulfur-rich lignite deposits. The clouds of smoke have given the region its name. Over time the sulfur dioxide from the smoke has acidified the shallow ponds (< 1 hectare or 2.5 acres area and < 1 metre or 3.3 feet depth) in the tundra dotting the area, down to a pH lower than 2. Elevated concentrations of metals (aluminium, iron, zinc, nickel, manganese and cadmium) occur in these acidic ponds. Soils and sediments have also been chemically altered. The acidic biota in the ponds are characteristic of acidic environments worldwide, in contrast to the typically Arctic biota in adjacent alkaline ponds. Although the soil of the region contains much limestone, the buffer effect has completely disappeared.

The nearest community, Paulatuk, which is about 105 km (65 mi) east, is named in recognition of the coal found in the area, traditionally spelt "Paulatuuq" or "place of coal".
