The 2001 publication of the authoritative 13-volume edition of The Journals of the Lewis and Clark Expedition offered an opportunity to take a fresh look at one of the most remarkable adventures in American history. Clay Jenkinson, a preeminent Lewis and Clark and Jefferson scholar, examines the dynamics of the journals: how they were written, under what conditions, and what it took to trigger a journal mention. His analysis of what the expedition’s six journal keepers included in their entries—and what they did not—offers a deeper understanding of the greatest land exploration in North America.
