Partially Frozen Lake Winnipeg, Canada53.2N 97.9W
The large white area in this image is the frozen northern section of Lake Winnipeg, in the province of Manitoba, Canada.
In the full image, parts of Cedar Lake and Lake Winnipegosis (both west of Lake Winnipeg, with the former of the two just north of the latter) are also frozen.
The other, unfrozen parts of the lakes reveal a variety of colors from sediments and algal growth. The southern parts of Lake Winnipeg are dark brown, while Cedar Lake and nearby smaller lakes show colors ranging from blue to gold to green.
Lake Manitoba, south of Lake Winnipegosis, appears mostly bright green with tan sediments lining the southern shores.
