St. Cloud has the nickname "Granite City" because of all the high-quality granite that was quarried in that area for nearly a century and used in buildings around the world.
Many of those quarries have given up their stone by now. Since 1998 about 20 of them – many now filled with water – have been part of a Stearns County park popular for hiking, swimming, rock climbing ans scuba diving.
Dan Thour used a drone to capture an aerial view of the park and his video was posted by Stearns County.
