The year-round hill fumes acid

Smoke Hills (Smoking Hills) is located on the east coast of Cape Bathurst, in Canada's Northwest Territories, adjacent to the Arctic Ocean and a small pool of lakes.

Smoking Hills - year-round hill fuming with acid

In 1850, British captain Robert McClure piloted the Investigator to the North Pole to search for the missing expedition led by Admiral John Franklin.Franklin's 129-person expedition left England five years ago.(Photo: Rebrn).

According to Amusing Planet, Investigator travels north through the Pacific Ocean and into the Arctic Ocean through the Bering Strait, then east to combine with another British expedition ship from the northwest.(Photo: Panoramio).

When McClure's search team arrived at the Horton estuary in the Beaufort Sea near Cape Bathurst, Canada, he saw smoke from the hills far away.Doubtful that smoke might come from Franklin's bonfire, McClure immediately sent a team of sailors to investigate.(Photo: Ponant).

The investigation team spotted dense columns of smoke rising from the spray mouths on the ground.The sailors returned with a smoldering stone sample.When they put the specimen on the table, it created a hole in the wood.(Photo: Featherlight Photography).

At that time, McClure said that the stones originated from volcanoes.However, scientists discovered this hilly area contains large sulfur-rich lignite deposits, which can catch fire immediately when the hills erode and mineral circuits come into contact with the air.(Photo: Wikimedia Commons).

Smoke emanates from coal mines containing sulfur dioxide, sulfuric acid and water vapor, causing nearby shallow lakes to become acidic and creating a unique biota that contrasts with the organisms in alkaline reservoirs close.(Photo: Wikimedia Commons).

According to scientists, the burning of coal mines at Smoking Hills has been going on for centuries and will continue in the future.(Photo: Wikimedia Commons).
