"Archaeological field work may be of two principal types. The first, logically, should consist in reconnaissance work, exploration and survey of a certain area. The purpose is to learn whether the region considered is of archaeological interest, the nature and extent of the remains to be found, their geographic distribution, possible significance and cultural relations. In other terms, it is supposed to lead to the preparation of a preliminary archaeological map and inventory of sites, a general description of the finds, a suggestion as to direction of further exploration and the selection of sites to be excavated. It must be extensive and informative. The second type of field work, on the other hand, is rather intensive and exhaustive, but limited to a site or group of sites. It deals with detailed information, with cultural sequence and characteristics, with depth and stratification, the time element, while survey work refers more to space, description, and general information.
     Since in Eastern Colorado neither type of archaeological work had ever been done, it was natural to begin by a systematic survey of the country. It was also timely, since the southwest corner of Colorado had been studied over a long period of years by several institutions and connected with the Pueblo culture, since northeastern New Mexico and western Oklahoma had been investigated by an expedition of the Colorado Museum of Natural History the previous year, and since survey work was also done in Nebraska and states East, the exploration of Eastern Colorado would link these two centers of activity and contribute a much-needed knowledge of the High Plains. The project was approved by the Smithsonian Institution, which supported the expedition to the extent of one half the expenses, the University of Denver, assisted by the Colorado Museum of Natural History, contributed the balance of the funds needed for the work. The Museum was especially interested in obtaining all available information concerning palaeontology of Eastern Colorado which could be gathered while surveying the country for archaeological purpose."     E.B.
