The first step in an archaeological excavation or survey is the selection of the site. Information such as who lived there, how old it is, and what timeframe it covered is what archaeologists first need to learn about the site at this stage. Through the use of such things as maps, photographs, regional studies, oral histories, and historic documents of surrounding sites, the archaeologists accomplish this initial analysis. Once this is done, the possible results of the excavation must then be assessed by the archaeologists. Whether or not the work done at a site will yield innovative or duplicated results is taken into consideration. Careful deliberation must also take place to determine whether or not the proper funds, technology, and human resources are available to perform the excavation properly, because the information that comes from a site can only be viewed once.
