Inscription. The steamboats that plied the waters of the Missouri were known as Mountain Boats for their ability to travel close to the headwaters of the Missouri at the Rocky Mountains. Missouri River steamboats were built different then their counterparts on the Mississippi River. To navigate the narrow, shallow channels of the Missouri, the boats were designed with stern wheels and used pine instead of oak on their decking and bulkheads to lighten the boats. Most boats drew about 20 inches of water when they were empty and up to 4 feet loaded.

Smaller steamboats were still used for short halls and ferrying short distances for many years.
