This image taken from the International Space Station shows the city of Green Bay at the southern end of icebound Green Bay, Wisconsin. This arm of Lake Michigan is six miles wide as seen in this view. The heavy snowfalls of the winter of 2014 cover the landscape. Combined with low sun illumination of a winterís day, all surfaces appear shades of gray. Fields appear brighter (top right, lower right), the cityscape (lower half of the image) appears as a checkerboard of grays, and forests (top left) appear dark.
The center of the city lies on the Fox River, one of the few larger rivers in the United States that flows north. Open water appears as dark patches at the mouth of the river where a power station emits warm water. Thinner (grayer) ice can be detected where slightly warmer water extends from the river mouth towards Long Tail Point, an ancient shoreline of the bay. Crews aboard the ISS do not usually take such detailed photographs because of the difficulty of getting sharp images with long lenses (in this case a 1000 mm lens). Streets and bridges crossing the Fox River appear quite clearly.
