State Geologist Discussing the “Built up” terrain in Bandon. 2014.
We discuss the origin of the rock on our property and during the conversation we get the math wrong. 90mm is 9cm is less than 1/10th of a meter. Duh.
Still 3 inches per year? Bear in mind this motion was during an epoch when the continents were undergoing much greater rates of deformation than today.
