1. According to Ordway, Reubin and Joseph Field were among them. (back)
2. In his Field Notes, Clark gives these figures as the weights of the water of the two rivers (see below, the combined entry for June 26–29, 1804). Biddle gives the figures, in degrees, as the specific gravity of the two kinds of water. Specific gravity is usually expressed as the ratio of the weight of a substance to the weight of an equal volume of pure water at the same temperature. Coues (HLC), 1:33. (back)
3. The captains applied the term "Black Mountain" or "Black Hills" to all the eastern outlying ranges of the Rockies, then known chiefly through Indian information. At this time, geographical theory postulated a pyramidal height of land in the west, from which the Missouri, Kansas, Colorado, Columbia and Rio Grande del Norte (Clark's "Del Nord") rose and went their several ways. Before Lewis and Clark, the Anglo-Americans had little conceptions of the extent and complexity of the Rocky Mountain region; as Clark observed, the features of this region were "not well assertaind."

4. Although there are a number of known Kansa villages on the Kansas River in the area noted, the identity of the two villages has yet to be determined. Wedel (KA), 52. (back)
