Hurd's Deep is a deep underwater valley in the English Channel, northwest of the Channel Islands. From marine navigational charts, the maximum depth is 180 m , and lies to the north of the isle of Alderney. It is most probable that it was named after Captain Thomas Hurd RN , by Admiral Martin White.
The underwater valley system found on the floor of the eastern English Channel formed from a catastrophic flood which was caused by a breaching of a rock dam at the Strait of Dover, which released a huge proglacial lake in the southern North Sea basin. The flood scoured the former river systems to form the Hurd Deep in late Quaternary times.
