STS068-230-083 Thunder Bay, Ontario, Canada October 1994
Thunder Bay, a Canadian port city along the northwest shore of Lake Superior, is visible (center of image). This image also shows a rugged, glaciated landscape, especially south of the urban area where low escarpments can be seen. Even Pie Island, southeast of the city exhibits a rough surface terrain. Cultural features include the crossing runways of Thunder Bay International Airport (southwest of built-up area); Highways 11 and 17 as well as the Thunder Bay Expressway (around the north and west side of the city); and cultivated field patterns along the Kaministikwia River Valley (west of the city). The unusual pattern on the surface waters of Lake Superior may be the result of strong surface winds.
