Where on Earth?


Aerial view of Experimental Lakes Area Lake 302 located on the Precambrian Shield of northwestern Ontario, approximately 250 kilometers east of Winnipeg. It is one of 58 small lakes that the Canadian and Ontario governments have set aside since 1968 for use in ecosystem-scale experiments and long-term monitoring. While Lake 302 was the site of eutrophication experiments in the 1970s and later for acid-rain experiments, other lakes have served as sites for research on contamination by metals, such as mercury.
