Stair Hole, Jurassic Coast, Dorset
Looking through the sea arch at Stair Hole in Dorset gives a sense of the relentless power of the waves and the remarkable durability of the Jurassic Coast.
Over time the sea will erode a larger and larger hole in these rocks and eventually the roof will cave in leaving a pillar or stack. There is a blow-hole here too, a sea cave where the roof is open – eroded from above and below – allowing the ocean to force its way up through the rocks like a spouting whale on stormy days.
This is a beautiful and geologically interesting coastline stretching c. 95 miles from Orcombe Point in Devon to Old Harry Rocks in Dorset.
