1. The courses and distances appear to be the only entry for August 10, 1804, in the Field Notes. The similar brevity of the Codex A entry for this day suggests that Clark had little time or energy left at the end of the day. A figure near the course heading appears to be 19¾. (back)
2. Coupée à Jacques means simply "Jacques's Cut." Part of it apparently forms present Blue Lake, at Lewis and Clark State Park, Monona County, Iowa. Atlas map 15; McDermott (WCS), 150; Osgood (FN), 103 n. 8; MRC map 26; MRR map 72. (back)
3. Two quarries along the valley and bluffs near Fort Calhoun, Nebraska, have been excavated in limestones of Pennsylvania age, but no sandstone is reported in them. The Dakota sandstone (Cretaceous) has not been reported in this area. The hill is immediately north of Decatur, Burt County, Nebraska, and appears prominently in Nicollet.
