Instead of the almost inscrutable lands of the western orogen, we are now poking among braided thrust faults, telescoped facies boundaries and sedately sprawled Early Cretaceous plutonic suites in the northern miogeocline in pursuit of either a cryptic great fault, or 2000 kilometres worth of distributed dextral smearing, or both.
