Junction of Chalk and Tertiary Strata at The Warren Wood, 2001. Differential erosion of the Chalk (to the left) and the soft Tertiary sediments (to the right) results in an abrupt change of coastal orientation at this point. The Chalk erodes very slowly and its coastal slope has become vegetated. The Tertiary sands and clays fail readily and loose debris is removed from the toe by wave action. These cliffs yield some beach forming sands that drift northward (to the right).
