What is archeology?
Archeology is the study of the material past. It is a way of studying people, like anthropology (study of culture) and history (study of events). All three disciplines, and their sub-disciplines, are put to work in Yosemite to understand the story of humans in the park.
In Yosemite, the focus of research is ancient peoples, American Indians, and groups after the Mariposa Battalion entered the Yosemite Valley in 1851 (which include European-Americans, African-Americans, Asian-Americans and more). With over 1500 archeological sites identified in the last 100 years, Yosemite has a rich diversity of human stories told through artifacts left behind. At least 10,000 years of humans visited or lived in what is now Yosemite National Park. We know that thanks to archeological research. Just like today, past peoples left their mark.
