Exploration in the period 1668 to 1689 was initiated by the re-emergence of the English in James Bay. This map shows the routes of seven expeditions into inadequately known areas of Hudson Bay and James Bay: Gillam and Des Groseilliers (1668 to 1669), Bayly and Radisson (1670 and 1671), Bayly (1674), Grimington and Abraham (1686) and Kelsey (winter of 1688 to 1689 and summer of 1689). The map also shows the extent of territory known to Europeans and the navigation of all exploration routes in the period 1651 to 1760. The historical names found on the map are derived from contemporaneous maps and written documents of the period.
