Age of cessation of orogenic event is strongly imprinted in the thermochronological record.

Thermal relaxation towards conductive equilibrium is responsible for rapid cooling of upper crust.

Resulting age-elevation trends do not reflect exhumation rate.

This explains the presence of “ghost” or “static” peaks in detrital age datasets

Care must be taken when interpreting thermochronological data.

End of orogenic event erases information concerning pre- and post-orogenic rates.
