We used to refer to Storrs Hill, a prominent outcrop of sandstone (now with added graffiti), as the 'Ups and Downs'. A lesser outcrop was the 'Little Ups and Downs'. In my childhood it was mainly open with sandy clay slopes, colonised by tussocks of fine glossy grass, dotted with scrubby thorns.
Over the next 30 years the bigger hill kept its gorse, thanks to occasional fires, while it's smaller sibling became overgrown with sycamore and bramble. The 'Little Ups and Downs' has recently been bulldozed which makes its origins more obvious. There's a small rockface of sandstone fronted by mounds of quarry spoil and the intervening hollow has been filled in as a rubbish dump. Fragments of stoneware jars and blue and white china suggest that the tip was in use in Victorian or Edwardian times.
The cleared area won't stay clear for long. Japanese Knotgrass is springing up already.
