Chalk dry valley on Askerwell Down
Dry valleys are relict landforms left over from the ice age. During the ice age, ice plugged all the pore spaces in the chalk rendering it impermeable. During the summer months meltwater would carve a valley and create the feature. After the ice age the chalk became permeable and porous and all surface water was lost leaving an obvious water carved valley, but now dry.
