Basin and Kechika Trough are bounded to the north and east by North American platform strata. Both basin and platform strata are deformed by fold-and-thrust deformation (note the limit of the Cordilleran overthrust belt). The transition from the broad Selwyn Basin to the narrow Kechika Trough has been
