Post-glacial Rebound near Håkansön

I attended a genealogy seminar on 25 September 2016 at the Swedish Club in Seattle, put on by SwedGen. The final portion was on the historical maps available from Landmäteriet. I’ve used that web site for the current maps, mostly as a gazetteer. I didn’t know the historical maps were available.

So I poked around looking for maps of Håkansön, the village where both my great grandparents are from. Some of the old church records identify the farm numbers where my family lived. Unfortunately, I haven’t found any land reform maps for the village, which would show the individual farms.

But there were some general maps for the area, and I noticed something interesting. The first image is from Google Maps of the peninsula today. The marker on it shows where Håkansön was according to the old maps (I thought it was slightly south of there).

The second image is of the same area on a map identified as being from 1858-78. The peninsula is shorter, with an island just off the tip.

What was an island in the 1800s is now part of the mainland. I’m betting the change in sea level is due to post-glacial rebound. The entire area was under thousands of feet of ice 20,000 years ago. and it is now rising because the weight no longer presses down.

Kind of neat to see a long term geological process actually reflected in the maps.
