OK, talking about states (the US). (Not sure if I've already posted this, altho' I did a search and nothing came up)
The northern-most, southern-most, western most, and eastern-most states (all 50) in the US? (Not counting US Territories)
Not what you'd think...not four states at all.
Only two:
Hawaii is southern-most
19.8987° N, 155.6659° W (Florida is 27.6648° N)
Only one fulfills all three other positions: Alaska.
Northernmost (obviously).
Westernmost: the Aleutian
Islands bump right up against the 180th meridian.
However, one Island, Attu, lies at 52°54'09"N
172°54'34"E situating it in the
eastern half of the Northern Hemisphere.
That is, it bumps up against the 180th meridian, but from the other side of the meridian compared to all the other Aleutian Islands.
