The Flint Mines

The project’s volunteers recorded and mapped flint mining sites across the Brecks, both ground-truthing existing site records as well as discovering previously unknown sites.

Training sessions for the volunteers enabled them to identify characteristic gunflint mine features such as the sub-circular shafts encircled by waste dumps – these always have one or two entrance breaks to allow access to the mine shaft.  Mines were usually spaced at 5 to 10 metre intervals, reflecting the management of the industry.

The following mine sites were investigated during the project.  to read more about a mine, please click on it’s name.
