to the very precipitous sides of the valley and others not 

 frequently seen elsewhere. These we have represented 

 according to our best understanding of them, and it is hoped 

 that the larger map, together with what is here written 

 concerning the valley, will need no further explanations. A 

 second map has been prepared, in which are embodied the 

 results of our sketches on our road back to Fort Bridger, 

 together with such information as we could obtain from the 

 inhabitants, and an old map which Judge Carter was kind 

 enough to lend us, which latter, however, we found incorrect 

 in some particulars. This map we give as a mere hint as to 

 the relation between Fort Bridger and the Smith's Fork 

 Valley. The third map contains the skeleton triangulation 

 of the main map. In this map the distances and heights are 

 given in feet. As the heights have been given already we will 

 only here repeat the distances :

A noticeable feature of this region is the scarcity of birds, 

 reptiles, and insects. We saw only a few snakes and lizards 

 on these plateaus. Musquitoes are very numerous in the 

 months of June, July, and August, after which, we under- 

 stand, they disappear. The deer-fly is a ferocious insect, 

 very much like the common horse-fly, but larger and with 

 irridescent colors, sometimes yellow, green, and red being 

 banded together on its head. They go in swarms, attacking 

 both man and beast, and are a terrible scourge to animals. 



We have chosen to name one of these peaks (our point No, 

 u) Santa Anna Mountain, from our faithful Mexican guide.
