Summary Cranberry Bog is a lowland moss which developed originally in a small shallow glacial hollow which contained open water during the late‐ and early post‐glacial. After a brief transition stage ombrogenous peat began to form and continued to do so throughout zone VI. An unusual feature of the bog is a well‐developed ‘Grenzhorizont’ which was not formed as a result of changes in climate. The late‐ and early post‐glacial vegetation of the area was transitional in character between that described from the Northumberland lowlands to the north and that described from the Yorkshire lowlands to the south, although it more closely resembles the former. Several unusual features of the pollen diagram, high birch frequencies throughout and low alder frequencies in zone VIII, are best understood in terms of a locally dominated pollen spectrum.
