Hi Jonathan - Just following up here... you should be able to see some new historical boundary information on OHM at http://www.openhistoricalmap.org/#map=6/47.665/-116.136&layers=H. If it doesn't pop up at first, be sure to clear your browser cache. These are old borders of American territories and states.
I just loaded this info yesterday & am still playing with the tagging a bit. I've highlighted some of those fields in the screenshot here: https://imgur.com/a/bL34gkC. These boundaries are overlapping and hence, a mess. I'm hoping to use this data as a test for the time slider work underway.
