About this site
Big Blue is a dive site in Iowa, located near the town of Blue Earth-area waters along the state's southern border, close to the Minnesota line. Inland dive sites in this part of the Midwest are typically former quarries flooded after mining operations ended, drawing local and regional divers for training and recreational dives. The surrounding landscape is flat farmland typical of north-central Iowa.
