Greylake
Greylake is a 9.3 hectare geological Site of Special Scientific Interest near Middlezoy in Somerset, notified in 1987.
This site, on the Somerset Levels, consists of 20 low-lying fields in the north west corner of King's Sedgemoor, and includes the Royal Society for the Protection of Birds Greylake nature reserve which has taken over arable farmland and is now home to lapwings, snipe, curlews, redshanks, yellow wagtails, skylarks and meadow pipits.
This location is the type section for the Pleistocene Burtle Beds, as it is probably the most complete Burtle Beds
sequence in Somerset. It demonstrates a sequence of fluvial gravels, marine intertidal silts and marine subtidal. Rich molluscan, ostracod and foraminifera assemblages and a mammalian fauna, including red deer, aurochs and fallow deer have been recorded.
Greylake was flooded during the winter flooding of 2013–14 on the Somerset Levels.
