“Moulton has produced a day by day narrative of the expedition, based on the journals and notes made by the captains, their men, and assistants who helped them catalog their work upon their return. The result is a fantastic resource for anyone—scholar or casual reader—who is interested in the expedition.”—Mark A. Eifler, Western Historical Quarterly
