 By the time Champlain arrived, the Algonquins and Mohawks were both using the Saint-Lawrence Valley for hunting grounds, as well as a route for war parties and raiding.Neither nation had any permanent settlements upriver above Tadoussac, the trading post in the lower St. Lawrence Valley which had been important for years in the fur trade.Although historians and other scholars have been studying the St. Lawrence Iroquoians for some time, such knowledge has been slower to be part of common historical understanding.
