Some interesting footprints on the beach.

There are major difficulties in investigating human history immediately before the coming of agriculture some 10,000 years ago because of the lack of evidence for early fishing villages along the coast lines of the world. The problem arises because during the last ice age sea levels were 100 metres or more below the current levels and this would suggest that any remains could be buried deep underwater. A recent discovery of footprints in the sand said to be about 13,000 years old suggests that there is one place where evidence has been preserved at sea level.

The place is Calvert Island, British Columbia, and earth movements (presumably mainly due to the growth in the Rocky Mountains) mean that locally the sea level has only risen by a few metres since the Ice Age low. In addition the fact that humans appear to have been on the island at the time suggests that they had sea-going boats. I look forward to future developments from this site - but unfortunately the realities of plate tectonics means that there are not going to be similar sites in Europe of Asia.
