The Ordnance Survey's 1947 to 1948 revision of its six-inch series recorded it as a quarry, giving it the quiet dignity of a named, documented feature. By the time anyone went to look at it in person, in 1984, it had long since fallen out of use, leaving only that waterlogged depression in the bog as evidence that something had once been extracted there.

What was taken out, and when, is not recorded. The site's post-1700 date places it beyond the scope of formal archaeological investigation, which tends to focus on earlier remains, so it exists in a kind of administrative no-man's-land: recent enough to be disqualified from one category of scrutiny, obscure enough to attract no other. Bogland quarries of this period were often worked for stone to be used in local building or road construction, though nothing in what survives about this particular hollow confirms that. It is a feature defined almost entirely by absence, both the absence of the material once dug from it and the absence of any detailed account of why it was dug at all.
