STS068-200-059 Thunder Bay, Ontario, Canada October 1994
Located on the northwest shore of Lake Superior the color infrared image captures the overall physical setting of Thunder Bay, a dynamic industrial and transportation hub for this region of Canada. The general outline of the urban, built-up area is discernible on the picture. The thin, linear feature that skirts along the west side of the city is the Thunder Bay Expressway (also known as Highways 11 and 17). The two intersecting runways of Thunder Bay International Airport are faintly visible along the southwest side of the urban area. The meandering, thin dark line that makes a 90 degree turn to the east is the Kaministiquia River. Notice that the color infrared image helps to accentuate and map the numerous cultivated (red) field patterns (actually showing the location and distribution of healthy green vegetation) west of the city. The dark, irregular shaped features are lakes. The larger island southwest of Thunder Bay is Pie Island.
