Cavers Discover 200-Year Old Mine, Untouched Since the Moment It Was Abandoned
Found in northwest England, the cobalt mine is perfectly preserved due to a lack of oxygen

Members of the Derbyshire Caving Club have uncovered a cobalt mine in Cheshire, England, that operated in the early 19th century.

Sealed off from oxygen, the site contains a “time capsule” of artifacts from the day workers abandoned it, shedding light on what mining was like some 200 years ago, according to a statement from the National Trust, which owns the site.

The small town of Alderly Edge has been a mining destination since the Bronze Age. While the caving club, which has leased the mines since the 1970s, has discovered other mines in the past, the newly-discovered mine is in “pristine condition,” says caving club member Ed Coghlan in the statement.

“This mine hasn’t been disturbed by later mining, it’s not been broken into by kids in the 1960s, it’s not been filled with bottles or other rubbish,” Jamie Lund, a National Trust archaeologist, tells the Guardian’s Esther Addley. “It literally is a time capsule in terms of giving a glimpse into the environment that these miners, who were extracting cobalt, encountered.”

Artifacts found in the mine include shoes, clay pipes and a windlass—a type of winch that would have been used to lift heavy objects. On clay handle holders, the miners’ fingerprints are still preserved, as is the imprint of one miner’s corduroy pants where he leaned against a wall.
