428 SIDNEY POWERS— THE SOLITARIO UPLIFT 



Prom the analogy of the Wells Creek Basin it is believed that the 

 original doming of the Solitario was caused principally by tectonic 

 forces. It is further believed that the symmetry of the dome is related 

 to the preexisting structure in the older rocks, which was probably anti- 

 clinorial, this structure forming a locus for the concentration of stresses 

 developed during the folding of the Cretaceous rocks.
