Clark: July 17, 1804

July 17, 1804
Missouri River near Platte River mouth
AI Summary

The expedition stayed at Bald Pated Prairie to fix the latitude and longitude and reset the chronometer, which had run down two days earlier. Clark calculated the latitude at 40° 27' North and measured the river's current. Lewis rode out to Neeshnabatona Creek, finding handsome country and a rapid, muddy stream that runs within 300 yards of the Missouri. Hunters brought in five deer and two fat catfish. Several men suffered from troublesome tumors. The southeast wind briefly brought swarms of mosquitoes before blowing them away.

July 17th Tuesday, we concluded to lay by today to fix the Longitude, and
get the Cronometer right, (She run down Day before yesterday), Several men
out hunting to day Capt. Lewis rode out to Neesh-nahba-to na Creek which
passes thro. the Prarie (on which there is Some few trees) within ____
Mile of the Missoureis, wind from the S E. Several of the party have
tumers of different Kinds Some of which is verry troublesom and dificuilty
to cure. I took a meridian altitude (43° 27′) which made the Lattitude of
this place 40° 27′ 6″ 4/10 North.(The Ball Hills bear N 25° W for
30 mes. The bend on L. S. passing the Isd. on the right Side is N. 28° W.
4 ms.) Took equal altitudes Tried a part of the comn pt. of the Current in
40 Seconds the water run 50 fathem 30″ & 20″ in places

Cap Lewers returned, Saw Some hand Som Countrey, the Creek near the high
land is rapid and nearly as muddy as the river, & rising Gutrich
caught two verry fat Cat fish G Drewyer Killed 3 Deer, & R Fields one,
a puff of wind brought Swarms of Misquitors, which disapeared in two
hours, blown off by a Continuation of the Same brees.

July 17th, Tuesday. We decided to lay by today to fix the longitude and get the chronometer right (it ran down the day before yesterday). Several men were out hunting today. Capt Lewis (Capt. Lewis) rode out to Neesh-nahba-to na Creek (Nishnabotna Creek), which passes through the prairie (on which there are a few trees) within ____ mile of the Missouri. Wind from the SE. Several of the party have tumors of different kinds, some of which are very troublesome and difficult to cure. I took a meridian altitude (43° 27'), which made the latitude of this place 40° 27' 6" 4/10 North. (The Bald Hills bear N 25° W for 30 miles. The bend on the L. S. passing the island on the right side is N. 28° W., 4 miles.) Took equal altitudes. Tried a part of the common point of the current: in 40 seconds the water ran 50 fathoms; 30" and 20" in places.

Capt Lewis returned. He saw some handsome country. The creek near the highland is rapid and nearly as muddy as the river, and rising. Gutrich (Goodrich) caught two very fat catfish. G. Drewyer (Drouillard) killed 3 deer, and R. Fields one. A puff of wind brought swarms of mosquitoes, which disappeared in two hours, blown off by a continuation of the same breeze.


Bald Pated Prairie, July 17th, Tuesday 1804. We concluded to lay by at this place today to fix the latitude and longitude of this place and to correct the chronometer (run down Sunday). Several men out by daylight hunting. Capt Lewis (Capt. Lewis) decided to ride out to Neesh-nah-ba-to-na Creek (Nishnabotna Creek), which passes under the Bald Hills near this place, and at one point a little above this camp is within 300 yards of the Missouri. On this creek grow a few trees of oak, walnut, and mulberry. I took a meridian altitude of the sun's lower limb (43° 27'), which made the latitude 40° 27' 5" 4/10 North. Wind from the southeast. Several of the party much afflicted with tumors of different kinds, some of which are very troublesome and difficult to cure. Capt Louis (Capt. Lewis) returned in the evening. He saw some handsome country and says that the aforesaid creek is rapid, muddy, and running. This creek, which is 10 or 12 from its mouth, within 300 yards of the river, is at least 16 feet lower than the river. The high lands from our camp in this Bald Pated Prairie bear N 25° W up the river.

The common current, taken with a log, runs 50 fathoms in 40". Some places much swifter, in 30" and even 20 seconds of time. Five deer killed today.
