NORTH DAKOTA STATE UNIVERSITY - FARGO, N D
OF FARGO, NORTH DAKOTA
The United States' U2 spy plane remains one of the most remarkable aircraft ever built. With its ability to fly at both high speeds and high altitudes, it has played a key role in reconnaissance since the late 1950's.
Unlike the previous images, which were computer-processed from satellite digital data, this image represents a true photograph taken from a U2 aircraft flying about 50,000 feet above the region. We are uncertain of the exact date of the fly-over, but it is likely in the late 1970's. Infrared film was utilized: grasslands and lawns reflect as red; buildings and streets as light gray, and cultivated fields as dark gray or black.
North is to the top of the photograph. The runways of Hector International Airport are apparent in the northwest corner. The North Dakota State University campus position is labeled. The elongate, N-S directed features in fields in the southeast corner of the image probably represent grooves formed from where icebergs floating in glacial Lake Agassiz dragged against the bottom sediments.
