FOOT HILL SECTION. 369 



Above this blue limestone was a body of yellowish limestones and 

 sandstones, with some red argillaceous strata, of a thickness of about 500 

 feet, succeeded by another blue limestone, very dark and compact, from 

 which was obtained 



lUiyncJionella UtaJiensis. 



In a thickness of about 1,000 feet of beds, largely blue limestones, next 

 above, no fossils were found. Above this, in a bed of about 50 feet of limy > 



shales, with greenish clays, were : 



Eumicrotis Hawni. 

 Eumicrotis, sp. ? 



Next north were about 200 feet more shales, then blue and gray sili- 

 ceous limestones, next, rather soft limestones with seams of white calcite, 

 and more siliceous limestones, a thickness of about 300 feet, above which 

 were obtained, from some clay-slates, two undetermined varieties of Avicu- 

 lopeden and an Eumicrotis. From here to the mouth of Parley's Canon, a 

 thickness of about 500 feet is composed principally of limestones, gener- 

 ally soft, sometimes siliceous and broken, but in which no fossils were found. 

 In these, the dip has steepened to 65° north, with a strike due west. At 

 the immediate mouth of Parley's Canon is a bed of about 50 feet of white 

 quartzite, with 100 feet of red sandstone, somewhat metamorphosed on 

 either side, all dipping and striking as above. 



North of this point, the dip shallows to 40° north, and the beds strike . 

 north 40° east. They consist of alternating siliceous, rather quartzitic beds, 

 with various blue limestones and limy shales ; the dip steepens again, and 

 seems almost reversed, but beyond the limestones are found red and pinkish, 

 rather loose-grained sandstones, with colored clays, characteristic of the 

 Triassic, dipping south, showing that there had probably been some faulting. 

 These sandstones sweep up on the spurs above, where the red beds can be 

 easily traced from below, forming an anticlinal fold on the front of the spur 

 between Parley's and Emigration Canon, of which the western end has » 



been cut off and eroded, and exposing again on the extreme foot-hills more 

 Permo-Carboniferous forms in the little anticlinal of blue limestone and clay-
