About this image
Taken from the banks at Beckingham looking North towards Union Mill (derelict) which was used mainly for crushing oil seed. It was was a working mill in 1907, but was disused by 1922, by which time Trentholme Brick and Tile Works (rear left, off North Warren Road - previously North Marsh Road) was replaced by (Council?) refuse destructor.
The Aegir (tidal surge, like the Severn Bore) heading up the river past Saundby. Ashcroft Mill at Gainsborough is visible on the far bank, and at this point, the River forms the county boundary between Nottinghamshire and Lincolnshire. The Severn Bore and Trent Aegir are naturally occurring tidal waves. These natural phenomena occur in the lower reaches of a few rivers throughout the world with large tidal ranges, including the River Severn and the River Trent. The Trent Aegir is named after the god of the seashore or ocean in Norse mythology - and like the Scandinavian sailors in the myths, river people would fear the coming of the aegir as it is very unpredictable and would sometimes surface to destroy ships. It usually appears during high spring tides, but as with the Severn Bore, its size can be affected by winter floods and the resulting rise in water level. The size of a bore or aegir can also be affected by opposing winds or high freshwater levels which reduce its height and delay its time of arrival, whereas a following wind can increase its height and advance the time it arrives.
