Whitestone Pond on Hampstead Heath may have been the highest point in
the old LCC area (though actually I think there is a higher point off
Spaniards Road a little to the north-east of the pond).

ISTM that if a pond were the highest natural point in an area, it would
soon go somewhere else.


The pond is man-made, and its man-made edge will stop the pond from
going anywhere else. ISTR Bell Moor, the first block of flats in East
Heath Road, has a blue plaque on it stating that it is built on the
exact highest point in the old LCC.
