Above this section comes a cliff of red, pink, and gray sandstcnes 
apparently embracing the Vermilion Cliff sandstone and possibly a part 
of the White Cliff sandstone, not examined in detail. No lower 
beds are exposed in the valley. 
The upper 1044 feet of the section represents the fossiliferous 
Triassic beds immediately below the Vermilion Cliff sandstone which 
is here well developed. The next 44 feet of beds is provisionally 
referred to the Permian, and in that case represents the basal portion 
of that series. It may possibly belong with the underlying Pennsyl- 
vanian Series, or partly to the overlying Triassic, if the conglomerate, 
No. 22 of the section, be taken as the base of that series. 
From the limestones of the Pennsylvanian portion of the section, 
Nos. 1 to 20, inclusive, we obtained the fossils shown by column 
IV of the table on p. 672. Probably no other exposure near 
near Moab reveals so great a thickness of the Pennsylvanian strata 
as that we examined, but doubtless the upper fossil-bearing limestones 
may be found in Spanish Valley. It is not known whether they are 
continuously exposed in the canyon of Grand River from Moab to the 
mouth of Cafion Colorado. The southwesterly dip of the Spanish
