From the time of earliest French and Spanish penetration into the mid-continent region, the Kansa Indian villages were an important stopping point for explorers and traders. The region was the most productive source of high-grade beaver furs, which were in great demand in Europe (Hoffhaus 1984). Beginning early in the 18th century, French-Canadian voyageurs ascended the Missouri River to Kawsmouth and beyond on a near-annual basis.
One of these early Frenchmen was Etienne Veniard, Sieur de Bourgmont. He undertook a remarkable journey in 1713 to explore the Missouri River as far as the Platte. Following his return to France, he was given a charge to establish a permanent post on the Missouri River in order to make peace and to trade with native Indians. This was accomplished in 1723 with construction of a small stockcade, known as Fort Orleans, near the modern town of Brunswick in central Missouri. In 1724, de Bourgmont once again ascended the Missouri River to the Kansa villages near modern Fort Leavenworth. There was much feasting and many speeches during his visit (Hoffhaus 1984). De Bourgmont continued westward onto the plains accompanied by about 1000 Indians! However, he was struck down with fever and had to return to Fort Orleans.
At Kawsmouth, Lewis noted, the waters of the Kansas is verry disigreeably tasted to me. Although he did not elaborate, there is a good physical explanation. In late June, the Missouri River would have carried considerable fresh runoff from melting snow in the northern Rocky Mountains. In contrast, the Kansas River has its headwaters in the Great Plains region and does not reach the mountains. In central Kansas, subsurface salt beds contribute high salinity to springs and streams that feed the Kaw River. Water of the Kansas River indeed would have tasted poor in contrast to the Missouri River.
The Missouri and Kansas rivers seen by Lewis and Clark were quite different from the rivers of today. The river channels were wide, shallow, and filled with sand bars and small islands. The character of the old Missouri River is indicated by the map below from the late 19th century, prior to management by the U.S. Corps of Engineers. The modern Missouri River is a single, deep channel flanked by levees and maintained by dredging. In the 20th century, bottomland was reclaimed for airports, railyards, and other industrial development.
Throughout most of its length from the Mississippi into the Dakotas, the Missouri valley is a broad avenue, in many places more than five miles (8 km) wide. However, near Kansas City, the valley is quite narrow--see images. Stream erosion of the valley bluffs is restricted by resistant limestone bedrock, and the valley is only about two miles (3 km) across. The limestone has been exploited in many underground quarries, which now are utilized for storage and office space in several parts of the the city.
