5 Golden Cap Lyme Regis ~ Charmouth ~ Golden Cap

6 The cliff top at Black Ven Black Ven between Lyme Regis and Charmouth. Upper Greensand lies over Lower Jurassic clays. The largest coastal mudflow in Europe took place here in the winter of 1958/9 The coast is unstable because there are numerous situations where porous strata, principally the Chalk and Upper Greensand, lie over impermeable clays.

7 How Landslides occur

8 Chesil Beach Isle of Portland The Fleet West Bay (west) Pebbles are ’sorted!’ Portland (east) The gradient of the beach can get very steep

9 The Isle of Portland When the island was uplifted, a series of massive fractures developed in the limestone.

10 Weymouth is a traditional seaside resort. It is protected by the Isle of Portland. Portland Harbour (South of Weymouth) Weymouth

12 Day 3 – Ringstead Bay to St. Alban’s head Durdle Door ~ Lulworth Cove ~ Stair Hole ~ Warbarrow Bay ~ Tynham ~ Broad Bench ~ Kimmeridge ~ Winspit

13 Durdle Door ~ A Limestone Arch Eventually the arch will collapse to leave a sea stack

14 Limestone Headlands Soft sand and clays Chalk Hills stop the cove eroding any further inland Lulworth Cove

15 Small arch is only gap in the limestone. Marine processes eroding further inland Stair Hole

16 The formation of Lulworth Cove, Stair Hole and the future

17 Worbarrow Bay Tyneham from Gadd Cliff (Note the land use) Broad Bench

18 Kimmeridge Bay – A wave cut platform

19 Chapmans Pool St. Alban’s Head Waves shape the coastline. Winspit Winspit (behind)

21 Dancing Ledge (+ tidal pool!) Looking out to see from Anvil Point Durlston Head Peveril Point Swanage Bay Old Harry Sandbanks Studland Anvil Point

22 Swanage Bay Swanage

23 Old Harry Rocks – A stack Stack New cave forming Collapsed Undercutting means stack will collapse

24 Studland – Sand Dune System Fieldwork (transects!) Little Sea 3 Major dune ridges

25 Development of Studland – Blown Sands Little Sea

26 View over dune slack with further vegetation succession Younger dunes with Marram Grass Actual fieldwork! Hmmmmmm!
