I posted the pic above to demonstrate how Alaska can be the most Easterly, and Westerly state of the US. It shows how the Aleution Islands cross over the 180 degree line seperating East and West.
Thats the simple bit.
I think the confusion comes from when
@Philw pointed out that the far East point of Russia in that pic also crosses over the 180 degree line, which should then make that part of Russia the most Westerly point (using the Alaska logic).
Yet when i look it up on google it says the most Westerly part of Russia is
https://en.wikipedia.org/wiki/Kaliningrad_Oblast
which is a small bit of land North of Poland.
