I realised Acomb must be vaguely scientifically interesting when I found it mentioned in Martin Lister‘s 1683 Royal Society paper “An ingenious proposal for a new sort of Maps of Countrys, together with Tables of Sands and Clays, such chiefly as are found in the North parts of England…”
Lister’s idea was that rocks and sediments should be mapped, for economic purposes, and he included “Acome near York” in his sand table:
It was only today, however, when I was dragging my daughter round Acomb on an Easter bunny hunt, that I discovered where Lister’s sand probably came from. As said daughter entertained herself in the Acomb Green play area, I spotted an information board, which said this:
I am sad I shall never hear the Acomb sand-hawker’s cry on the streets of Leeds, but I shall henceforth refer to Acomb Green as Yarcomb Sand’oil.
Looking at the British Geological Survey’s map of the Quaternary deposits around York, Acomb Green appears to sit on clayey gravelly sand of the York Moraine Member (shown in green below). However, the lilac-coloured unit to the south-east is simply mapped as ‘York Moraine Member – Sand’. Perhaps the Yarcomb Sand’oil might have lasted longer if they’d dug there instead?
