THE VALLEY CITY GRABEN, UTAH 573 
Along the bottom of the graben plain, toward the base of the 
scarps on both sides, the beds show high local dips that are pre- 
sumably the result of drag along the fault planes. 
While the identification of the beds in the graben plain was 
wholly on lithologic grounds and was rendered somewhat difficult 
by scarcity of outcrop, there seems to be little doubt that the fore- 
going interpretation is the proper one. And while grabens are by 
no means rare, a graben occupying the axial line of a well-defined 
anticline seems sufficiently unusual to merit some attention. The 
area is probably complicated by cross-faulting. Since only one 
day was spent studying the structure, it is more than probable that 
important features escaped detection. ‘The entire region is one that 
offers possibilities of interesting structural and stratigraphic work. 
The topographic expression of this structure is clearly shown on 
the old United States Geological Survey La Sal Reconnaissance 
sheet, east of the road leading from the railroad to Moab. The 
two inward-facing scarps with the central valley and the outward 
dip slopes are plainly marked. 
While no detailed work was done at Moab, the writer has seen 
some evidence to lead to the conclusion that the Moab plain, 
extending southeast from the village of Moab, is possibly also a 
similar graben.
