Bob Saunders and companions spent six summers between 2006 and 2012 hiking, canoeing, and kayaking their way through much of the mainland Arctic. Their epic journeys significantly overlapped not only with Franklin’s overland expeditions, but also Back’s in 1834, and Rae and Richardson’s searches for Franklin in the late 1840s and 1850s.
