[post_page_title]A bit of history[/post_page_title]
The Blue Lake is not a natural formation. It is actually a former quarry – a sort of open-pit mine in which different types of rock can be dug up from the ground. In this case, the rock being dug up was slate, a material known for its durability and attractive appearance that has a variety of uses – most commonly, flooring and roofing.
The quarry dates back to 1867, when the slate industry was growing rapidly in North Wales, and it was later flooded as part of a failed plan to transform it into an hydroelectricity reservoir. It is said that the stirred up minerals from its quarrying days are responsible for the characteristic blue color of the lake’s water.
