Sergeant Floyd Monument | Sioux City

The Sergeant Floyd Monument, located on a bluff overlooking the Missouri River in Sioux City, Iowa, is a towering memorial dedicated to Sergeant Charles Floyd, the only member of the Lewis and Clark Expedition (1804–1806) to die during the Corps of Discovery’s journey. It is a National Historic Landmark and one of the most important monuments along the Lewis and Clark Trail.

Historical Background
Sergeant Charles Floyd, a Kentucky native and one of the 33 expedition members, fell ill and died on August 20, 1804, just a few miles south of present-day Sioux City. His death was likely caused by a ruptured appendix, making him the only fatality of the entire expedition. He was buried on a bluff near the Missouri River, a site that became sacred to local and national history.

In the late 19th century, erosion threatened his original grave. Floyd’s remains were reburied higher up the bluff, and in 1901, the Sergeant Floyd Monument was erected to permanently mark his final resting place. It was the first National Historic Landmark designated in the United States in 1960.

Obelisk Structure: The monument is a 100-foot-tall white stone obelisk, modeled after the Washington Monument in Washington, D.C.

Materials: Constructed of Kettelson stone quarried in Minnesota, designed to withstand the test of time and weather.

Surrounding Park: The monument sits in a landscaped park area with walkways, interpretive signage, and views of the Missouri River valley.
