EXPLORATIONS FROM A. D. 1843 To A Dp. 1852. 63 
MAP OF NEW MEXICO, COMPILED BY LIEUT. J. G. PARKE, TOPOGRAPHICAL ENGINEERS, IN 1851. 
This map, by Lieut. Parke, was a careful compilation of all the available and reliable 
information in relation to New Mexico which could be obtained at that date from trappers and 
hunters, as well as from actual sürvey. It was prepared by him, while in that country, by 
order of Brevet Colonel Jno. Munroe, United States army, commanding 9th military depart- 
ment, and was drawn by R. H. Kern in 1851. It was subsequently reduced in the Bureau of 
Topographical Engineers, and published on a scale of thirty-six miles to an inch. 
RECONNAISSANCE FROM SANTA FE TO FORT LEAVENWORTH, IN 1851, BY CAPTAIN J. POPE, TOPOGRAPHICAL 
ENGINEERS. 
Captain Pope travelled on the Cimarron route as far as Cedar creek, where he turned north 
and struck the Arkansas at the Big Timbers. Crossing this river he took a northeast course 
to the Smoky Hill Fork, and came upon it near where Captain Frémont struck it in 1844. 
From this point he travelled down the stream. 
The map constructed by Captain Pope would make it appear that what had been considered 
the source of Smoky Hill Fork, taking its rise near the sources of Bijou and Boiling Spring 
creeks, was probably that of the Big Sandy or some other tributary of the Arkansas. 
SURVEY OF CREEK BOUNDARY, BY CAPTAIN SITGREAVES AND LIEUT. WOODRUFF, TOPOGRAPHICAL 
ENGINEERS, 1850-'51. 
The report and map of this survey form printed House Ex. Doc. No. 104, 1st session 35th 
Congress. The map is on a scale of 1 to 600,000, or about an inch to nine and a half miles. 
Chain and compass were used in the survey, and the longitude of Fort Gibson was determined 
by moon culminations. A sextant was used to determine the latitudes. 
The northern line begins on the parallel which passes near the mouth of the Red fork of the 
Arkansas, at a point a little west of north from Fort Gibson, and continues west on the parallel 
to the 100th meridian. Of this line about seventy-nine miles were surveyed in 1849 by 
Captain L. Sitgreaves, Topographical Engineers, and one hundred and twenty miles by Lieut. 
I. C. Woodruff, Top. Engineers, in 1850, who also surveyed the north fork of the Canadian from 
this boundary line to its mouth. "The boundary was not ipM SEES west of the 99th meridian. 
RECONNAISSANCE DOWN THE ZURI AND COLORADO RIVERS, BY CAPTAIN L. SITGREAVES, UNITED STATES 
TOPOGRAPHICAL ENGINEERS, IN 1851. 
The report of this forms Senate Ex. Doc. No. 59, 2d session of 32d Congress, and is accom. 
panied by a map of the routes pursued, on a scale of ten miles to an inch. The reconnaissance 
was made with a compass and estimated distances, and chécked by astronomical observation 
made with a sextant. 
This expedition, under Captain Sitgreaves, assisted by Lieut. J. G. Parke, RO 
Engineers, Mr. R. H. Kern as topographer, and Dr. S. W. Woodhouse, surgeon and naturalist, 
was ‘organized at Santa Fé, New Mexico, and consisted of about twenty persons, including 
packers and servants; pack mules being used for transportation of provisions, &c. The party 
accompanied an expedition against the Navajoes as far as Zufii, which point they reached by 
the usual road from Albuquerque on the Ist of September, 1852. From this point, with an 
escort of thirty men of the 2d artillery, the exploring party travelled down the Zuii river to
