USA and Canada Ideas - Generally from North to South
Alaska: Sorry it's such a mess! Most of this is just moving mountains around - Circles for adding mountains and slashes for removing them. Also moving two tiles up on the far west side to create a little peninsula. Readjusted the river. Note that the mystery lake in the north should become a mountain. In southern Alaska, 124, 80 should become water, and 125, 80 should become land.
Dene: Expanded a bit. Essentially Yukon plus the Northwestern chunk of the NW Territories. Again mostly moving mountains around, but (26, 88) and (132, 85) should become water.
Nunavut: Removing land tiles. Circled lake tiles should become land.
Athabasca: Separate the lake into two lakes. Neither of the two current lake tiles there in the western part of the territory should remain water. Not sure if the rivers here are possible to do alas. 142, 80 should become water.
British Columbia: Moving mountains around.
Keewatin: Shrunk the borders a bit to more closely match the historic extent. Added a couple rivers. Remove marked land tile in the northern area.
Quebec: Just some rivers and adjustment of the Labrador border.
Saskatchewan: Recommend renaming to
Campi Canadienses (Canadian Prairies). Shrunk Lake Winnipeg - should just be the lowest lake tile plus the one marked with a red circle.
Southern Canada: Fixed rivers a bit; Smoothed out the borders but can be left alone if desired.
Oregonia: Remove mountain tile for Helena. Rivers.
Dacota: Remove mountain tile for Lame Deer. Rivers.
Great Lakes: Rivers shifting - Proposed a potential split; Western portion (Minnesota, Iowa, Missouri) could be split as Missuria. (EDIT: Alternatively, could just give Missouri (the lowest state in this region) to Louisiana and leave the rest as Great Lakes.)
California: Add tile for Monterey; Remove mountain for Reno.
Nivata: Shuffling moutains around - red lines denote mountains to remove; circles denote either add or remove. Suggest renaming to
Oasisamerica.
Southern US: Moved the Appalachians closer to the coast - Recommend renaming to
Appalachia. Remove mountain for Atlanta. Could potentially add tile on the northeast edge for Dover/Delmarva peninsula - not a huge deal though.
Texas: River and border tweaks.
