In those eons the plateau country was flat and much lower than its heights today, which are typically 5,000 feet (1,524 meters) above sea level. Winds also contributed raw material, the makings of ...

In this case, the trace of the PHE conductivity Tr[X] is in direct proportion to the Chern number of the WP, and is robust against many system details, leading to a flat plateau at low energy.
