by Catherine McGrew Jaime (Author) Now, in larger, easier to read print. The Lewis and Clark Expedition was filled with adventures and danger. Most of us know something of its travelers, almost all being familiar with Captain Meriwether Lewis, Captain William Clark, and Sacajawea. But one important member of the Expedition if often overlooked, Clark's slave York. This short story tells the tale of the Corps of Discovery from York's perspective. We join York as he shares the stories of his adventures with his grandchildren, in his cabin in Kentucky. While the setting is fictional, as well as the family he may or may not have ever had, the adventures he shares with them are based in history.
