Research for my Caterham Project:
What makes the place what it is?
In the beginning it was the sea, which stretched across all of what we know now as the south of England. During the Cretaceous period, over almost unimaginable lengths of time, the calcified remains of minute algae and other fossil debris drifted slowly to the sea bed eventually to form the ridges of chalk that make up the North and South Downs.
Rather comically, the image looks like a bunch of buttons.
