As the cold weather began to settle into the Madison area, the temperature of Lake Mendota, the largest of the Chain of Lakes in Madison, was significantly warmer than the surrounding air resulting in some foggy mornings. Here are some photos from those foggy mornings.
Here is a photo of Maple Bluff (about 3/4 mile [1.2 km] across the lake from where I took this photo and about 120 feet [36.5 meters] above the lake at this point) shrouded in the fog.
Here is a photo of part of the City of Madison shore (foreground) with fog on the lake.
Here are two views of the Tenney Park breakwater in the early morning with the fog in the background.
