This lookout, accessible for free, is located on rue du Lac Noir in the Black Lake sector. It offers an exceptional point of view on the pits, transformed into a turquoise blue lake, as well as on the mining installations of the BC Mine. Recall that this mine, opened in 1908, whose operations were interrupted from 1928 to 1936, was closed permanently on November 1, 1997.
To get there: Meet at the Magasin Général O'Brien, at 4233 Rue du Lac-Noir, Thetford Mines, QC G6H. The belvedere is opposite, at the top of a staircase of about fifty steps.
Where does this turquoise color come from? Fine particles suspended in water reflect the blue and green wavelengths of sunlight. The effect is accentuated by the background of clear rocks.
At all times, except the winter period
The reputation of ancient mining pits filled with turquoise water goes beyond the borders of the Thetford region. But where can we observe this phenomenon? Here's a list of the best places to see it, believe it, and share it on social media!
