STS61A-048-0094 Denver, Colorado, U.S.A. November 1985 The dark, forested Front Range of the Rocky Mountains provides a dramatic and abrupt landform change from the western edge of the Great Plains. Visible at this scale is little of the infrastructure of Denver--some street grid patterns; dark, irregularly shaped lakes and reservoirs scattered across the urban area; and part of the north-flowing South Platte River. The picture was taken prior to the construction of the Denver International Airport northeast of the city.
