parallel thrust faults and folds make up a fold-thrust belt on a regional scale. at the local scale segments of the belt are connected by transverse zones. the charleston transverse zone mentioned earlier runs perpendicular to the thrust faults within the sevier belt. it has been debated among geologists if this transverse zone developed during the sevier orogeny or the uinta/cottonwood arch formation during the laramide orogeny. mapping sevier thrusting in the basin and range province suggests sevier structures curve around the uinta/cottonwood arch defining the uinta recess. looking closely at sevier faults in american fork canyon indicate that these faults are the oldest in the charleston transverse zone suggested by cross cutting relationships observed in the area.
