The Current Archaeology piece on human footprints at Happisburgh in Norfolk can now be read (part thereof) online – go to www.archaeology.co.uk/articles/features/first-impressions-discovering-th… (see the earlier post on 19th February).
Some fascinating information is drily observed. For example, the sediments appear to be river or estuary silts and mammoths and other Ice Age mammals have been found nearby in a similar sediment and contemporary deposit. Iron minerals in the sediments are oriented towards the magnetic pole – and in this instance, during a period of reversal. Compasses today point north but when these sediments were laid down they would have pointed to the south.
