The Pinnacles, Chalk stack formation in Studland, Great Britain.
The Pinnacles are two white chalk formations that rise from the sea near Handfast Point, with one prominent stack and a smaller stump shaped by waves and wind. The rocks stand as distinctive features along the coast and show how natural erosion has carved the shoreline over time.
The chalk structures began forming around 66 million years ago as part of a continuous ridge that once connected to the Needles on the Isle of Wight. Over millions of years, the sea wore away this ridge, leaving behind the isolated rock formations we see today.
These rock formations mark the start of the Jurassic Coast, a UNESCO World Heritage area recognized since 2001 for showing the story of the Earth written in stone.
The best way to view the formations is to follow the South West Coast Path from Studland, with parking available at the National Trust facility nearby. Choose a clear day for the best views and wear sturdy shoes, as the clifftop paths can be uneven and exposed to wind.
The formation of these rocks happened through a gradual process where the sea first carved caves into the chalk, which then became natural arches before eventually collapsing. This ongoing reshaping by waves and weather means the exact shape of the stacks changes year after year.
