The expedition travels about thirteen miles up the Mississippi camping opposite present Chester, Illinois. Lewis describes the range of hills forming Cinque Hommes Cape and reports three grist mills and several settlers living in the area.
Brazeau Creek
Set out this morning before sunrise— (1) ¾ of a mile to the mouth of this river it is about 18 yards wide at it’s mouth and affords but little water at this moment, tho’ I am informed that there is a handsome settlement on it & that in high water it navigable many miles, it heads with the waters of the Saline of Mississippi & the St. Francis rivers—

Above: the three vessels under sail, ascending the Mississippi River. At this point in their journey, to accompany their barge, the Lewis and Clark Expedition had acquired two pirogue vessels: one white and one red. I did this painting on a beautiful September day, at a scenic overlook next to Fort Kaskaskia, Illinois. On November 28, 1803, they arrived at the Fort with about 24 men.—Steve Ludeman
A Bold Point of Rocks
This is a bold point of rocks forming the extremity of a range of hills which have continued on our Lard quarter for a considerable distance the Creek of the same name which puts in just above it is 20 miles in length and has a considerable number of inhabitants on it, and as many as three gristmills.—

Of all the celestial observations the captains took, the simplest was to calculate latitude from a Meridian Altitude—a noon observation of the sun. They only needed a sextant or octant and a nautical almanac. Unlike longitude, an accurate clock was not necessary. For more on the procedure, see “Latitude” in Kansas River Observations by Robert N. Bergantino.
