Ecofacts are types of environmental information that can be used to give an idea about the environment of an area at the time people lived there and about foods people ate. Animal bones, charred seeds, pollen, and soil type are ecofacts. These are sometimes useful in interpreting why people moved into or out of an area. Ethnohistory is the use of historic accounts about a group, usually written by outsiders, to give information about that group. Explorers, soldiers, traders and missionaries drew maps, described cultural practices and provided a range of information.
