Caption: A 70mm infrared frame of the city of San Francisco, taken on a clear day. The gray areas represent urban regions and the red areas are vegetated. Within the city of San Francisco, places such as Golden Gate park and the Presidio at the base of the Golden Gate Bridge easily stand out from the well-developed parts of the city. Major thoroughfares and bridges (Golden Gate and Bay Bridges) are shown, as are landmarks such as Candlestick Park and Alcatraz. The trace of the San Andreas fault show as a straight valley running northerly along the San Francisco peninsula. Good detail is visible in the turbid waters of San Francisco Bay.
