  • A purple mottled sunset as the winter sun sank over the horizon. A nice grassy walk up the golf course (new clubhouse being built cost 1.7M) keeping a healthy distance back from the cliff edge. Trig missing - splash? The chalk cliffs and foreshore at Seaford Head reveal a marine environment dating from the Late Cretaceous epoch, 89-86 million years ago. Fossils occur commonly throughout the chalk, in particular echinoids, sponges, bivalves, that inhabited the prehistoric seafloor at the time when Seaford Head and much of Great Britain, along with Europe, lay beneath a relatively shallow sea around 40N of the equator, on an equivalent latitude to the Mediterranean Sea today. Global sea-levels were over 200 meters higher.The purity of the chalk indicates its formation took place far from land, mostly free of terrestrial sands and silts that would otherwise have coloured it. During the most recent ice age, between 115,000 - 10,000 years ago freezing winds cut across the exposed land, carrying with them weathered sands and soils. These sediments, known as loess, form the crumbly sandy layer seen at the cliff top.
