Wisconsin Historical Society — Charles Floyd Journal

The Wisconsin Historical Society Library and Archives at the University of Wisconsin-Madison holds the Charles Floyd Journal, one of the most important primary source documents of the Lewis and Clark Expedition. Charles Floyd was the only member of the expedition to die during the exploration of the West, succumbing to what is believed to have been a ruptured appendix on August 20, 1804.

Additional Lewis and Clark documents are preserved in the Draper Collection, one of the most significant manuscript collections relating to frontier history in the United States.
