Geograph - photograph every grid square

Filling up most of the width of the foreground of this image is a shallow pit. It is only on account of the light covering of snow that it is at all discernible in the photograph; the patchy snow cover in the interior can be contrasted with the unbroken layer of snow on its near side.

This shallow pit appears to be an outlier of the system of tracks and quarries mentioned in the end-note. There are other small inconspicuous pits nearby. Tracks (NS4378 : Old braided track) lead east, to this area, from the northern end of Black Wood; other pits beside those tracks are apparent on satellite imagery: for example, at NS43387789.
