The tide went out 4,000 years ago!

This morning I was presenting a session on using film, which took up the morning.  It was an early start as the presentation was in Norrfällsviken, an hour's drive from home, and it started at 08:30. After lunch I headed out on a walk around the headland that sticks out into the sea here.
This is a national park and part of the International World Heritage site.  The area has this status because the land is rising up as it rebounds from the last iceage, when the crust of the earth was pushed down by the weight of a 3000 metre thick layer of ice.
Here you can see a pebble beach that has been rising from the sea for the last 4,000 years at about 1 cm a year.
As you can see it’s a fairly hostile environment, with very little soil formed. Only in the oldest areas, in slight dips, has enough soli formed to support bushes and small trees.
My more usual view of this place is from the sea as I sail past so it was fun to come here on foot and look around the whole area.
It was a warm day and the sea is still warm(ish) from the summer so I even went swimming a couple of times during the afternoon.
A bit behind in my blipping so this is the second of four pictures that take us to the end of August.
