Here is a draft map, based on his descriptions in the comments to a recent post, showing the approximate borders of the successor states to the USA and Canada. I have yet to deal with states that are split between more that one nation in 2065.
from here, and US state, and Canadian province shapefiles from here. Update - I switched to using this map of Canadian provinces which includes Nunavut.
I have also used the ETOPO1 bedrock relief topographic map as a background, which shows the elevation of Greenland without the ice sheet. It is perhaps a century or two too early to assume complete deglaciation of Greenland. The portion of Greenland below sea level is not actually connected to the sea here, it would be at a +50 metre sea level as assumed in the 25th century setting of Star's Reach.
Update
I have made some updates based on further descriptions based on John Michael Greer's comments, which account for the states that are divided:The borders of the Retrotopia nations can be seen by the colours, with present-day US states and counties shown as lines.
The Lakeland Republic is not labelled since the Free City of Chicago label has prevented it from appearing. |
In this case the Lakeland Republic label wins out. |
These are the borders of the western areas, as far as I understand JMGs comments. |
Close-up of the north-east former USA and adjacent part of Canada. |
Black and white version. |
The shapefile itself containing all of the Retrotopia nations in North America I have made available here.
It is also available as a KML file suitable for use with Google Earth.
Showing 2 meters of sea level rise in blue, with 2-4 metres shaded in lighter blue. |
