ladd.1 GEOGRAPHY ELEVATIONS. 441 



The Yampah was gauged in the middle of November, near the ford 

 where the Bawlings wagon-road crosses, and this result also gives the 

 minimum amount of water in it at any season of the year. The width 

 was 156 feet, the deepest place 2.5 feet, the maximum velocity 2.4 feet 

 per second, and the amouut of water 364 cubic feet per second. 



In the spring these rivers are very high and impassable until nearly 

 July, and the Grand below the Blue is not fordable till August, and 

 then only in a few places. 



Plenty of water is naturally accompanied by an abundant growth of 

 timber, and about one-half of the whole area is so covered, though a 

 great deal of it is small, and of no value as lumber. 



The Park range is covered with good large timber, similar to the 

 Front range, mostly pines, but with aspens and small low trees along 

 the lower edges. The Park View Mountain range and the Medicine Bow 

 are the same, the hillsides well covered with flat areas, arms of the North 

 Park, clear and open. These flat areas are covered with the lake deposits, 

 and wherever these basins exist, as in Egeria Park, and the parks along 

 Yam pah, they are free from timber, with the exception of the cotton- 

 woods bordering the streams. 



The long sloping spurs from the White Biver plateau aud the heads 

 of the valleys draining it are well timbered, especially on slopes facing 

 the north. 



From the southeastern corner of the plateau, near station XLVII, and 

 the long ridge that, starting at this point, runs southwesterly from this 

 point around to the east and north to the mouth of the South Fork of 

 the White, and beyond it to station LV, the country is well, and in 

 places even heavily, timbered, coveringabout700 square miles. The best 

 timber, pine and spruce, grows on the heads of the White, Williams 

 Fork, and Yampah Bivers, and on the top of the plateau between Shin- 

 gled Mountain (station XLII) and station LIX. The spruce-trees grow- 

 ing on the top, at an elevation of from 10,500 to 11,000 feet above the 

 sea, are large and tine, often reaching 3 feet in diameter. 



A list is given of the elevations of the principal points and places. 

 A few are calculated trigonometrically and those are marked with a t, 

 and a few that are dependent upon an aneroid barometer are marked 

 with an a; the rest are all obtained from a mercurial barometer.
