Description: During this period ice once more advanced over the region and people were pushed south, returning when the ice retreated. In post glacial times migrant hunters spread across to the limestone uplands and occupied caves at Harborough near Brassington. The caves may have been used as base camps from which to intercept migrating herds of horses and reindeer. Animal bones found include wild horses, reindeer, woolly rhinos, hyena, bison, red deer and wild boar. There is later evidence of occupation around Harborough Rocks, where Bronze and Iron Age remains have been found.
