Wisps of frozen mist rise along the northern shoreline of Wisconsin on Lake Superior during a frigid January morning, as relatively "warm," saturated air over the greatest lake is captured in a north wind and drops its moisture when colliding with the colder, drier inland air. The temperature was -6°F (-21°C), and I took these images with the ubiquitous recorder of 21st century, a smartphone, across the narrow west end of the lake from above Duluth, Minnesota. The Wisconsin shore is already almost 15 miles (24 kilometers) distant at it's closest (right), and recedes farther to the east (left).
Such fogs are common on the coldest — typically sunny — mornings on Lake Superior, when the lake is not completely frozen.
