SALT ANTICLINES 



A zone of flexures and faults extends in a northwest-southeast direction 

 from east-central Utah into west-central Colorado. They consist basically 

 of eight elongate anticlines variously modified by collapse folds and 

 normal faults. Their position and orientation are shown in Figs. 26.7 and 

 26.12. Between the anticlines are simple and gentle synclines. Stokes 

 (1948) observes that their strike is common with that of the Uncom- 



pahgre Range of the Ancestral Rockies and suggests that this relation 

 points to a system of deep-seated breaks in the basement rocks. The prob- 

 lem is very complex, however, because the faults and folds (the Meander 

 anticline) have a northeast direction, and the great monoclinal flexures 

 a northerly trend. 



It is fairly certain that the structures are closely connected with salt 

 flowage and solution. At certain times and places, the salt and gypsum 

 have acted as ordinary rock and have suffered the same deformation as
