On Nov.27,1803, Lewis and Clark camped near this point, which at that time was the lower portion of Horse Island. Horse Island was located just below the mouth of the Kaskaskia River at the beginning of a sharp bend in the Mississippi. As a result of changes in the course of the river, Horse Island has been absorbed into the Missouri shoreline in the vicinity of this marker, and the Mississippi River has shifted its course eastward, carrying away the original village of Kaskaskia.

When the party reached Horse Island, Capt. Meriwether Lewis left his co-commander, William Clark, in charge of the keelboat and pirogues, while he was put ashore to walk the six-mile distance to Fort Kaskaskia. The fort was now an American Army post situated on the high ground on the east side of the Kaskaskia River opposite the village of Kaskaskia.

Clark and the rest of the men, meanwhile, pushed their boats into the Mississippi and begin to work their way around a long and difficult bend, known as Coco Bend. Clark had wanted to make calculations of latitude with his sextant but a thick morning mist obscured the sun. The west side of Coco Bend hugged the Missouri shore and Clark observed a range of highlands next to the river. At 1 p.m., the party passed Joseph Donahoe’s landing. Boats loaded salt from the salt works in Saline Creek at this place. Two hours later, Saline Creek itself was passed. In addition to the salt works on this creek, there was also a thriving settlement. The party rounded Coco Bend and pulled up to Kaskaskia Landing on the Illinois shore. On the opposite side of the river was the former west bank community of Old Ste. Genevieve, known locally as “misar” (phonetic for misère in French, or misery in English). This community was relocated after disastrous floods in the 1780s.

There is a roadside historical marker for visitors to glen into the times and landscape of 1803 when they camped here.
