Cropmarks of a possible prehistoric or Roman trackway, to the north-west of Calceby. Visible as an incomplete linear feature, defined by two parallel running ditches, with a rough length of 300m. Identified on aerial photography examined as part of the National Mapping Programme. {1} Cropmarks of what appear to be natural palaeochannels and former stream courses are discernible in this area on more recent Google Earth satellite imagery layers. The previously identified linear feature, thought to be a possible former trackway, could not be confirmed on this later imagery, although some of the cropmarks here may derive from archaeological activity. The exact origin and function of the previosuly identified feature remains uncertain. {2}
