Samuel Parker was a missionary who accompanied a fur-trading party on an expedition from Council Bluffs Iowa to the Oregon Territory. At the time, the region was claimed by both the British and the United States and was little known except to the fur-traders. Parker's map, based on both personal observation and reports of the fur-traders of the Hudson Bay Company, is a landmark in the mapping of the region. The map provides an excellent view of the river systems and tribal territory. It shows several forts, including an early depiction of Fort Hall. The map extends to include much of present-day Canada. The map is still bound in the original book in which Parker tells of his incredible experiences on the expedition. The book is the fifth edition of Rev. Parker's journal, which is often missing this important map. The books preface refers to the map as being "…far more accurate than any which has before been published."
