The Archaeological Complex at Leamy Lake Park, Hull, QuÈbec: When Nomads Stay Put and Sedentary People Move About Marcel LalibertÈ Projet archÈologique du lac Leamy Hull, QuÈbec An archaeological inventory carried out over the past three years within Leamy Lake Park in Hull, QuÈbec, resulted in the discovery of 14 prehistoric sites over a wide area. More than half of these appear to be gathering places. Located on the floodplain of the Gatineau River delta, at the juncture of the Rideau, Gatineau and Ottawa Rivers, Leamy Lake Park appears to have been originally only sporadically occupied by groups of Laurentian Archaic fishermen before becoming a summer gathering place for Point Peninsula groups during the Middle Woodland. At the end of the last millennium, the Gatineau River Delta was literally invaded by a variety of groups from neighbouring regions as well as by people from areas further north, west and south. The archaeological complex at Leamy Lake provides an unique opportunity to study the habits of nomadic peoples temporarily gathered together. It also allows us to examine the poorly known behaviours of otherwise sedentary groups which have left their communities to travel through foreign lands. This locale combines the documentary qualities of small sites with the difficulties presented by the analysis of gathering sites.
