EXPLORATIONS FROM A. D. 1832 To A. D. 1834. 31 
as represented. by Lewis and Clarke, and have so indicated them on my map of military 
reconnaissances in the Dakota country. The examinations made by me in 1857 somewhat 
modified that representation as regards their extent and position, but confirmed it in relation to 
the direction. 
MAE OF LIEUT. E. STEEN, T. 8. DRAGOONS, 1835. 
This map وهی‎ the NAM from the west boundary of س‎ and Missouri to. the 
Rocky mountains, between the 31st and 45th parallels, on a scale of twenty miles to an inch; 
it shows the route of the rangers, under Colonel Manny, in 1833, who made an excursion from 
Fort Gibson, westward, as far as the head of the Little river, and back, and of the routes of. 
the dragoons, under Colonel Dodge, in 1834~ 35. 
The expedition under Colonel Dodge, in the summer of 1834, went into the country lying 
between the Red and Canadian rivers as far west probably as longitude 100? 30, some seventy 
miles west of the Witchita mountains. This expedition, the object of which was to visit the 
Camanches and Pawnee picts, was very disastrous to the troops. General Leavenworth died 
of fever, and many officers and men perished from disease produced by the summer heats, bad 
water, and malaria. The report of Colonel Dodge (the only official one which I have seen) 
gives very little topographical information, and it would be difficult to trace out the exact 
route of the party. The artist, Mr. Catlin, was with the command; and a glowing account of 
the sufferings they underwent, and the places visited, with Kiss of scenes, can be seen in 
his work on the North American Indians. ' 
Captain R. B. Marcy, U. S. A., has since explored all this section, and information con- 
. cerning it can be found in his reports. 
The expedition under Colonel Dodge, in 1835, started from Fort Leavenworth, proceeded 
up the Platte and South Fork to its source; then travelled south to the Arkansas, and returned 
by it and the Santa Fé road to Fort erek 
: On the map of Lieutenant Steen the Cimarron river is — as flowing into the dilimi 
beum near the — of Fort Atkinson.
