Title: Birmingham and central Alabama area seen in Earth Resources Exp. Package
Description:
A vertical view of the Birmingham and central Alabama area is seen in this 
Skylab 4 Earth Resources Experiment Package S190-B (five-inch earth terrain 
camera) infrared photograph taken from the Skylab space station in Earth 
orbit. The Birminham industrial complex, with a population of nearly
850,000,  is the light gray area nestled in the valley between the
northeast-trending  ridges that rae prominent topographic features in the
southern Appalachian  Mountains. The narrow ridges and adjacent valleys
reflect folded and faulted  sedimentary rocks. Bankhead lake, formed by a
dam on the Black Warrior River,  appears as bright blue west of Birmingham.
Two lakes are formed by dams on  the Goosa River East of Birmingham.
Federal and state highways appear as thin  white lines and are easily
identified. Power line clearings are visible in  the center of the picture
along the Goosa River, and can be traced  northwestward to northern parts
of Birmingham. The predominant deep red color  of the picture is due to the
reflections from living vegetation. In contrast  are the light tan areas
that commonly occur as rectangular patterns in the  east part of the
photograph and represent mature agricultural crops or  grazing lands.
