Check out this amazing drone video from the Ruskeala Stone Park in the Karelia province of northern Russia. Karelia is one of the eleven republics that make up the Northwestern Federal District of Russia. It is situated between the St. Petersburg area and Murmansk, the northernmost Russian mainland province. What you'll see in the video are marble "canyons", created by the marble quarry operations which date to the 18th century here. A number of these quarries were destroyed from overuse of dynamite.
