The Silver Pit is a long valley in the bed of the North Sea, 45 km (28 mi) east of Spurn Head in England.
At some point in time the Silver Pit was part of the valley of the Wash River [citation needed].
Also notable is the Silverpit crater, a crater-like feature near the Silver Pit, discovered in 2002.
In origin, it is probably a tunnel valley (Benn & Evans fig.9.27) which was kept free of periglacial deposits by the Wash River when the sea level was lower, towards the end of the Devensian glaciation.
They found the small valley to be rich in flatfish, especially soles in winter.
