Jordan River and proceeds northward along the west side of that 

 stream, and second a branch of the Los Angeles & Salt Lake Railroad, 

 which connects the line running down Salt Lake Valley with the 

 main line at Boulder south of Stockton. The Denver & Rio Grande 

 Western Railroad descends at a steep grade, and at milepost 721 it 

 runs on the right bank of Jordan River, which has gravel bluffs 

 rising more than 100 feet on both sides. The top of the first terrace 

 (about 250 feet above the river), which is crossed by the Los An- 

 geles & Salt Lake Railroad, corresponds with the Provo shore line 

 and doubtless was a gravel bar built out across the channel when the 

 waters of the lake stood at the Provo level. The material composing 

 these terraces is well shown in the numerous cuts of the Denver & Rio 

 Grande Western Railroad and the trolley line across the river and 

 in an immense gravel pit open on the right at a siding called Xash, 

 at the lower end of the Narrows. At this place several large flumes 

 on the left take water from Jordan River and distribute it over the 

 low plain to the north. 



The river valley below the Narrows is well farmed and makes 

 a pretty picture as the traveler catches glimpses of it here and 

 there, but the river swerves to the west away from the railroad and 

 the traveler sees it no more. Near the siding of Olivers the railroad 

 emerges upon the plain and the traveler has spread before him on 

 the right the south end of the broad valley in which Salt Lake City 

 is situated, bounded by the great wall of the Wasatch Mountains, 

 as shown in Plate XCI. Here again the §hore lines of Lake Bonne- 

 ville are the most conspicuous features of the landscape. The trav- 

 eler may readily follow the uppermost or Bonne^nlle shore line by 

 the slight horizontal line across the mountain front which separates 

 the more rugged slopes above from the smoother and more gentle 

 slopes below. Below the Bonneville is another shore line, which 

 in some respects is much more prominent, as it is represented by 

 the uppermost terrace or the great bar built out from the moun- 

 tains to the east. Below this bar is the terrace which was made when 

 the lake stood at the Provo level and which is crossed by the Los 

 Angeles & Salt Lake Railroad in its course from Salt Lake City to 

 Provo. These terraces are shown in figure 61. 



On the left stands the Oquirrh Range in all its barrenness. The 

 traveler may think that this range is the very type of desolation 

 and of wortliless barren rock, but if the atmosphere
