The Dorothy Pecaut Nature Center is located in the heart of the northern Loess Hills, within Stone State Park in Sioux City, Iowa. The Center is owned and operated by Woodbury County Parks and is also where the Woodbury County Conservation Board is located.

The Lewis and Clark Expedition passed through present-day Sioux City after laying to rest Sergeant Charles Floyd, who died on August 20th, 1804 of what was likely a ruptured appendix.
