471 INTRODUCTION Archeologists and historical geographers are concerned with the discovery, study, and evaluation of past cultures and environments. In arid climates, the detection and delineation of archeological sites are relatively simple, especially where vegetation is sparse or absent. By contrast, detection may be extremely difficult in high-rainfall regions, e.g., tropical forests. Potential sites may not only be obscured by vegetation, but their ground scale alone may render them almost invisible to terrestrial observers. The vertical perspective afforded by aerial imagery thus provides a new dimension in the search for and delineation of archeological sites. And even when such sites are not clearly discernible, possible or probable locales for detailed ground exploration may be outlined by photographic or image analysis of envi ronmental and microenvironmental zones. Site detection may be accomplished by visual aerial reconnaissance or by employing various remote sensors such as aerial photography, infrared scanners, and microwave (radar) imagery. This brief review paper concentrates on the applications of vertical aerial photography and infrared imagery. HISTORICAL HIGHLIGHTS Early Developments One of the first practical applications of aerial archeology was demonstra ted in 1922 by Englishman O.G.S. Crawford, who utilized shadow marks, soil marks, and crop marks to delineate probable sites in the United Kingdom. His successes are exemplified by the fact that he discovered more Celtic, Roman, and "stonehenge" sites in one year than had previously been found during 100 years of ground reconnaissance. This work firmly established aerial techniques for archeological exploration in England. Crawford's subsequent investigations spread to Europe, the Mediterranean region, and eventually to the Americas in the late 1920's. In spite of notable successes, however, aerial techniques were still quite limited during this period because of shortages in trained personnel and the reluctant acceptance of this new methodology by individuals and institutions that were in a position to support and utilize the results of significant discoveries. The 1930's saw a period of little or no expansion in aerial archeology. However, a strong upsurge of interest developed after World War II because of improved cameras, film emulsions, aircraft, and the large numbers of persons who returned with wartime training in airphoto interpretation and aerial reconnaissance techniques.
