Starting at Flamborough North Landing (Welton and Burnham Chalk Formations - Turonian and Coniacian Stages of Upper Cretaceous)

Horizontal and dipping beds visible in the cliffs Tide mark clearly visible on the cliffs
North Landing, Flamborough - looking north - fairly low tide, July 2004 "Caves" worn into the cliffs by the sea
Close up of criss-cross faulting in cliffs Flamborough Head
Faulting in the chalk Moving South - this is Flamborough Head
Sink hole developing in the foreground Close up of the cliffs
Boulder clay is crumbling away near the path and forming sink holes Flamborough Head cliffs 
Cliffs eroded by wave action Cliffs on south side of Flamborough Head
At Flamborough Head, cliffs formed of flint-bearing Burnham Formation, overlain by flintless Flamborough Formation (Santonian to Campanian Stages) Deformation runs throughout the bay, part of the Howardian-Flamborough fault belt
Continuing South - this is Sewerby, access to the beach via a long flight of steps - Flamborough Formation (Campanian Stage of Upper Cretaceous)

North of the steps are the Flamborough Sponge beds - in the Inoceramus lingua  zone - some pictures of various sponges below

 Cliff face from Sewerby steps
Sponge fossil in the sponge beds More sponges near to Danes Dyke
Pen and walking stick for scale - Laosciadia plana fossil in the rock platform Compass clinometer for scale - these beds also had bivalve fossils
Walking stick for scale My walking stick for scale again
This sponge fossil is approximately 50 cm long Sponge from visit in March 2005
Dipping and faulted beds Cliffs near Danes Dyke
A slight change of direction as you round the corner going north - beds which had looked to be horizontal, once round the corner are dipping to the southwest Fault from top left to bottom right, through the dipping beds at the base of the cliff
Layering in the glacial till also quite obvious Close up of cliff
March 2005 - cliff fall Very fragmented and folded bedding at Danes Dyke 
Lots of fossil sponges in the scars The start of a line of cliffs which used to be the shoreline before the last Ice Age
Danes Dyke - eroded valley filled with glacial till - dug out by Bronze Age man! Sewerby - "buried cliff" - and only glacial till south of here along the coast to Spurn Point
