was named for William Garland, of Kansas City, the contractor for 

 the construction of the irrigating canal through Bear River canyon. 

 The red color on the mountain side opposite Dewey is produced by 

 a mixture of blue, gray, red, and pink limestone and limy sandstone. 

 Just north of Dewey the traveler gets the first glimpse of Bear River, 

 the largest stream draining into Great Salt Lake. This river has an 

 interstate habit; it rises in southwestern Wyoming and is crossed by 

 the Union Pacific Railroad near Evanston, flows northwestward into 

 Utah, back into Wyoming, crosses into Idaho, and eventually turns 

 southward to empty into Great Salt Lake. It also drains Bear Lake, 

 a body of water 20 miles long lying across the Utah-Idaho boundary 

 near the Wyoming line .^ 



Irrigation is practiced throughout the length of Bear River valley 

 wherever it has been possible to divert water from the stream at a 

 reasonable cost. 



Between Dewey and Collinston may be seen three conspicuous 

 wave-cut terraces 300, 500, and 640 feet above the track; the upper- 

 most one is the Bonneville and the lowermost the Provo terrace. 

 Several miles to the west on a clear day the parallel beaches can be 

 seen on the lower gentle slope of Blue Spring Ridge. Just before 

 reaching Collinston the train leaves the flat lake floor and ascends 

 through gravel cuts in an uneven surface to a slightly higher level. 



CoUinston is a small settlement surrounded by grain fields. Lake 

 terraces, like gigantic music staves engraved on the mountain, are 



beautifully preserved in this vicinity. The rocky 

 Collinston. knob just beyond the station is gray conglomerate 



Elevation 4,416 feet, (gravcl and saud cemented together) of Tertiary age, 

 Sn 40 ^^i* carrying an abundance of fossil snail shells. This rock 



is very young in comparison with those found in the 

 Wasatch Hange and is the remnant of a once extensive body of gravel 

 and sand which was deposited in a fresh-wat<^r inland sea that covered 

 this area just prior to or during the uplifting of the mountains* 

 Though geologically young, the rock in this knob is nevertheless hun- 

 dreds of thousands if not millions of years old, and ever since its for- 

 mation was completed and the lake was drained it has been subjected 

 to the washing of the streams which have crossed it, so that much of 

 it has been worn away. It has also been affected by movements 

 within the earth, as is shown by the fact that its once nearly horizontal 

 layers are now tilted and broken. 



North of ColUnston the raiboad climbs by easy grades still higher 

 above the plain, across which winds the deep-cut trench of Bear River.
