252 ANNUAL KECORD OF SCIENCE AND INDUSTRY. 



those numerous canons of whicli that of the White River is 

 one. Having completed their work by October 14th, the 

 party marched eastward through Middle Park, and, after 

 twelve days of rain and snow, reached Boulder City, Col- 

 orado. 



The field-work of the Yampah Division during the past 

 season was principally confined to a district of Northwestern 

 Colorado lying between the Yampah and White Rivers, and 

 between Green River and the subordinate range of mount- 

 ains that lies west of and parallel with the Park Range. 

 The area is embraced between parallels 29 30' and 40 20', 

 and meridians 107 30' and 109 20'. 



The party consisted of Mr. G. R. Bechler, topographer di- 

 recting, accompanied by Dr. C. A. White, the well-known 

 geologist. They proceeded southward from Rawlin's Springs, 

 a station on the Union Pacific Railroad, August 6th, toward 

 their field of labor. From Rawlin's Springs to Snake River, 

 a distance of eighty miles, table-lands form the chief feature 

 of the topography; while from Snake River to the Yampah 

 River the distance is more undulating, and thickly covered 

 with sage. Between the Yampah and White Rivers, a dis- 

 tance of fifty miles, the country is mountainous ; and on the 

 divide betw^een the Yampah and White Rivers the eleva- 

 tion is 8000 to 9000 feet. Mr. Bechler, after having formed 

 the geodetic connection with the w^ork of previous years, con- 

 cluded to finish the more mountainous portion of the area 

 assiQ:ned to him, wdiich besjan from a line of meridian with 

 the White River Agency, and extended westward to about 

 108 10'. Here the party found water and grass in abun- 

 dance, with one exception. The plateau country, however, 

 was so destitute of water, and so cut up with dry gorges or 

 caiions, with scarcely any grass or timber of any kind, that 

 traveling was rendered very difticult. The party, therefore, 

 made White River its base of supply for water and grass, 

 making side trips into the barren hill-tops or plateaus in 

 every direction. 



From the Ute Agency, which is located approximately in 

 lat. 38 58' and long. 107 48', the White River takes an al- 

 most due west course for fifteen or eighteen miles, most of 

 the way through an open valley, with here and there narrow 

 gorges. About fifty miles from the Agency the river opens
