The smoking hills are well believed to have been burning for
centuries, and will do so for many years to come. Most people perceive the
Arctic as a clean, pristine environment, but the Smoking Hills, located 350 km
east of the Mackenzie Delta, are a natural source of air pollution. In 1850, British Captain Robert McClure was
sent on an expedition aboard the Investigator to the Arctic to pursuit for the
lost expedition of Sir John Franklin who had departed England 5 years earlier.
It was the second exploration party who went searching for the 129-crew Arctic
exploration team, and one of several dozens that were to follow for the next
four decades.
Therefore, the Investigator sailed north through the Pacific
and entered the Arctic Ocean by way of Bering Strait, sailing eastward past
Point Barrow, Alaska to in due course link up with another British expedition
from the north-west. When McClure’s exploration party reached the mouth of the
river Horton on Beaufort Sea near Cape Bathurst in Canada's Northwest Territories,
he observed smoke in the distance. He is suspecting the smokes could be coming
from campfires, maybe from Franklin, McClure at once sent a search party to
investigate. The party found not flames from Franklin's campfires, but thick
columns of smoke emerging from vents in the ground. The sailors get back with a
sample of the smoldering rock, and set it down on McClure's desk it burned a
hole in the wood.
He thought that rocks to be volcanic, but the fact was
something else. The mountains contains actually a large deposits of
sulphur-rich lignite (brown coal) which ignite instinctively when the hills
erode and the mineral veins are exposed to the air. The fumes they give off
comprise sulphur dioxide, sulphuric acid and steam, all of which has acidified
the surrounding shallow pools making a pocket of distinguishing acidic biota,
in contrast to the typically Arctic biota in adjacent alkaline ponds. Though
the soil of the region contains much limestone, the buffer effect has totally
disappeared. The adjacent community, “Paulatuk or traditionally spelt Place of
Coal”, which is about 105 km east, is named in recognition of the coal found in
the area. Source: Charismaticplanet.com
