EXPLORATIONS FROM A. D. 1852 TO A. D. 1857. 87 
This expedition, consisting of about two companies, all mounted, under the command of 
Brevet Major G. P. Haller, fourth infantry, was organized by General Wool, in the summer of 
1855, for the purpose of chastising the Indiayg who had killed some emigrants near Fort Boisé. 
Leaving the Dalles, the expedition followed on or near the South Pass emigrant road, to 
about 70 miles to the east of Fort Boisé. They then took the new emigrant route, through 
Kamas prairie, known as Jeffries’ cut-off. (From the Kamas prairie an examination was made 
south to the Snake river.) On arriving at the junction of the Kamas Prairie creek with the 
: Malade river, the expedition turned to the north and proceeded up this to its source; thence 
. over to Goddin's river; and thence in a northerly course over to the Pash-a-ma-rah creek, which 
they followed to its junction with Salmon river. This latter stream was examined to the mouth 
of its eastern branch, called Mormon river, where the Mormon settlement of Lemhi is located. 
Returning, the expedition ascended Salmon river to its source, and then taking a northwest 
course, passed along the sources of the Moorumba and the Pashewahkite branches of the 
Salmon river. In a valley of the latter tributary they came upon some of the Indians whom 
they were seeking, and inflicted a severe chastisement. From this stream they turned 
southwest, crossing the mountains to the source of Payette river, which they followed to within 
twenty miles of its mouth, and then left to proceed directly to Fort Boisé. They returned the 
remainder of the way on the route by which they went out. 
SURVEYS OF ROADS IN MINNESOTA, UNDER CAPTAIN J. H. SIMPSON, TOPOGRAPHICAL ENGINEERS. 
Captain Simpson’s annual report for 1855, with a map on a scale of twenty-four miles to an 
inch, showing all the general government roads under his charge, forms a part of the annual 
executive document for that year. One of these roads extends from Point Douglas, on the 
Mississippi, to the mouth of St. Louis river; another from Point Douglas to Fort Ripley; 
another from Fort Ripley, on Crow Wing river, to Otter Tail lake; and another from the Men- 
dota to the mouth of the Big Sioux river. These are the principal roads. The one last 
mentioned was surveyed by Captain Reno in 1853. 
RECONNAISSANCE IN THE DAKOTA OR gm COUNTRY, BY LIEUTENANT G. K. WARREN, TOPOGRAPHICAL 
ENGINEERS, IN 1855. 
The report « of this forms Senate Executive Document No. 76, 1st session 34th Congress. It 
is | accompanied | bya map on a scale of 1 to 600,000, giving the detailed topography of the routes 
explored, and a general map of Nebraska, on a scale of 1 to 3,000, 000. 
While making this reconnaissance I was attached to the staff of General Harney, commanding 
Sioux expedition, and was assisted by Mr. P. Carrey and J. H. Snowden. Sketches of routes 
were also furnished me by Lieutenant G. T. Balch, U. S. Ordnance, and Lieutenant J. Curtiss, 
2d infantry. The instruments used consisted of odometers, compasses, and barometers. I 
left St. Louis on the Tth of June, and proceeded up the Missouri to Fort Pierre. A reserve 
was laid off and surveyed for that post, and the Missouri examined as far up as the mouth? of 
the Shyenne. On the Tth of August, in company with Mr. Carrey, I left Fort Pierre, with six 
men and one cart, for Fort Kearny, which point was reached on the 21st of August. Here, 
joining General Harney, I accompanied the army along the Platte on the route to Fort Laramie, 
at which place the last barometer was broken. From Fort Laramie the expedition went to 
Fort Pierre, over the route along White river, through the Bad lands, and along the ridge 
between the Little Missouri and Big Shyenne rivers. From Fort Pierre I returned to the
