The only evidence of its existence came from the air, captured in a photograph taken in July 1989, when the cropmarks of a fosse betrayed the outline of a subrectangular enclosure with rounded corners, measuring approximately 35 metres east to west. Cropmarks form when buried features such as ditches or banks affect the growth of crops above them, producing variations in colour and height that are legible from altitude but imperceptible underfoot. The fosse, a defensive or boundary ditch, would once have defined the perimeter of a settlement, most likely a ringfort-type enclosure of early medieval date, though nothing in the available evidence pins down exactly when it was in use.

The aerial photograph also recorded a macula, a dark stain or patch, within the eastern portion of the interior. Such marks can indicate pits, hearths, or areas of concentrated organic activity, the kind of subsurface traces left by sustained human occupation. Together, the fosse outline and the interior macula suggest a site that was once a functioning enclosed farmstead or settlement, now lying entirely beneath cultivated ground, known only because a particular combination of crop stress and summer light caught it at the right moment in 1989.
