LOCALITIES WHERE THE GROUPS CAN BE STUDIED. 51 



south side of Henry's Fork, commencing about two miles above its mouth 

 and extending for many miles to the westward. These beds stand on edge 

 and are well exposed. Their junction with the black shales can be plainly 

 seen and the base of the group is the second conglomerate below the teliost 

 shales; the teliost shales themselves constitute a conspicuous datum point 

 from which to study the stratigraphy of this district. Many sections can be 

 obtained on either side of the Uinta Mountains. Perhaps no better place 

 can be found than on Ashley's Creek, where the group stands in a hogback 

 near Dodd's Ranch. Many other localities could be mentioned on the 

 Price, Escalante, Dirty Devil, Paria and Kanab Rivers. 



FLAMING GORGE GROUP. 



This group can be well studied at the typical locality, viz, in the vicin- 

 ity of Flaming Gorge. Commencing at the conglomerate above mentioned 

 as forming the base of the Henry's Fork Group, you pass southward over 

 the upturned edges of the beds, crossing the bad-land sandstones, then the 

 Mid-group Limestones, then the bad-land indurated sandstones, until the 

 White Cliff Limestone is reached. The massive, cross-bedded sandstones 

 beneath, is a very conspicuous feature of the landscape, and forms the sum- 

 mit of the next group. 



In mentioning the typical and other localities of the foregoing groups 

 I have not given detailed sections, as in a following chapter, on the descrip- 

 tive geology of the Uinta Mountains and adjacent country, it will be neces- 

 sary to describe more minutely the stratigraphy of all these groups. These 

 typical localities excepting that of the Sulphur Creek Group all fall within 

 the area that is to be described. The typical localities of the remaining or 

 lower groups are without the region described in this volume, and hence I 

 shall give sections of the groups as they occur at the typical localities. 



WHITE CLIFF GROUP. 



The locality selected as representing the typical series of this group is 

 in Southern Utah. Here a long irregular escarpment or line of cliffs is seen 

 facing southward, from which the geologist may overlook two other sub- 

 parallel lines of cliffs and see in the distance the walls of the Grand Canon
