If you’re really into the Lewis and Clark Expedition, it’s a giveaway question. Of course! He’s the only one of the expedition who died along the way.

Quite early in the expedition in fact. They were exploring the Louisiana Purchase, and found themselves in Sioux City, Iowa on July 31. Floyd became ill at the end of July 1804 and took a very severe turn for the worse on July 31. It was appendicitis, an illness that no doctor was capable of treating at that time. He ultimately died what Clark described as a most painful death on August 20 and was buried on a bluff overlooking the Missouri River, named Floyd’s Bluff in his honor.

A riverboat was also named after Sergeant Floyd, which has now been turned into a museum covering the Missouri riverboat era. It is one of many visitor centers along the Lewis and Clark National Historic Trail

While it covers a wide number of topics related to the river boats on the Missouri River, it also offers the rare chance to view the pilot house on one of these boats. This one even had a friendly pilot on board.
