Long before pioneers, loggers and wealthy retirees discovered the charms of Lake Coeur d'Alene, its shores were considered prime real estate. Going back thousands of years, families have lived along the lake, fishing for mammoth bull trout in its blue depths and digging water potatoes near the shore. Archaeologists are now gathering evidence of prehistoric lakeside dwellers. In some areas, remnants of ancient villages have been found buried under deep layers of sediment. Some sites, however, have yielded only small flecks of charcoal from prehistoric hearths.
