I’ve just found this on google, they must have updated their satelite imagery, as it is incredibly detailed. This is where i got all the tarmac for my After the Rain piece. After asking a few road workers where i could get as much free old tarmac as possible I was directed to a depot in Greenwich. It was hard to find but i saw this black mountain as I approached the area. It doesn’t look that high from a satelite photo, but it is huge, as is the digger you can see perched ontop of it.
