If 20 Sites were a symphony (which of course it is) then sites 9 to 12 constitute its slow movement whose generally pastoral tone temporarily gives way to a bleak spareness.

This view was perhaps chosen for the distant and often haze-occluded prospect of another estate which in general outline has the look of a complex of Precolumbian ziggurats.

Here my presence was noted even in the first year by council workmen who the following year told me that they'd been looking after my mark for me (at every site we paint a cross to indicate the position for taking the photograph) and, in 1975, in order to relieve the view's monotony, put out their best mowing equipment to make an exciting foreground to the picture.

So little has so far happened here that there is time to notice the minutiae of change right down to the replacement of a section of plastic drainpipe. A splash of yellow paint (destined originally for road markings) seems uncharacteristically dramatic in 1988 and, such is the concentration allowed at this site, one remarks the scratching of this yellow mark in 1989. The appearance of a black circle in 1990 heralds the arrival of the First Dish to 20 Sites.
