"Sâh-câ-gar me-âh or bird woman's River"

The captains name a creek Blowing Fly after the blowflies that often congregate on raw meat and open wounds. At the mouth of the Musselshell, they explore and take celestial observations. A tributary of the Musselshell is named “Sâh-câ-gar me-âh [Sacagawea] or bird woman’s River”.

Elsewhere, the barge that headed down the Missouri from Fort Mandan on 7 April 1805, arrives in St. Louis.

Blowing Fly Creek

passed the entrance of a large Creek, affording but little water; this stream we named Blowing Fly Creek, from the immence quantities of those insects found in this neighbourhood, they infest our meat while roasting or boiling, and we are obliged to brush them off our provision as we eat.

The Muscle Shell river falls into the Missouri 2270 miles above it’s mouth, and is 110 yards in width, it affords much more water than streams of it’s width generally do below, it’s courant is by no means rappid, and from appearances it might be navigated with canoes a considerable distance

about five miles abe the mouth of shell river a handsome river of about fifty yards in width discharged itself into the shell river on the Stard. or upper side; this stream we called Sâh-câ-gar me-âh or bird woman’s River, after our interpreter the Snake woman.
