The Journals of Patrick Gass: Member of the Lewis and Clark Expedition, edited by Carol Lynn MacGregor

His simple and direct writing style, along with his emphasis on the daily activities of the trip, made Gass’s journal more accessible to the general reader than other firsthand account and revealed the optimistic spirit of the expedition.
