Edited by Carol L. Mac Gregor. Softbound, 460 pages, 6" x 9". Sgt. Patrick Gass’s journal, never widely available to a general audience, is the most readable and straightforward account of the Lewis and Clarkexpedition, largely because Gass focused on the human aspects of the epic journey. In this new edition, the author’s thorough annotation of the journal and the inclusion of Gass’s previously unknown account book from later in his life lend new insight into Gass’s work and his life.
