Stonebarrow is located about east of Charmouth and west of the hamlet of Seatown. Stonebarrow Hill reaches an elevation of about 155 metres. The cliff face, part of which is known as Cain's Folly, is about 140 metres high, which is about 50 metres lower than the neighbouring Golden Cap, the highest cliff on the South Coast of England. Rock falls occur on the cliff face very frequently, continually exposing new fossils. There are a couple of examples of biological weathering, especially on the sandy-soils on lower-lying cliffs.
