Guess the POD from this map?

Texas is more successful in their war of independence.

Also is this not something that should be posted in Alternate History Maps, Flags and Graphics.

Well Canada has lost most of British Columbia to the US but nothing else which suggests that this wasn't the result of a war but for some reason Britain conceding virtually all the Oregon region to the US. Quebec is independent but suspecting that is either it doesn't join the Federation or leaves later.

Texas seems to have gone berserk with sizeable gains from the US as well as much of Central America and assorted Spanish and British Carribean colonies and Alaska. This seems very ASB.

Only thing I can think of is that somehow William Walker's empire in central America becomes stable and part of Taxas, which would give them the lands in the isthmus and might result in them gaining Alaska. Possibly also they are somehow able to defeat Spain and gain Cuba plus general expansion means they take Hispaniola. However how they get Jamica and so much of the US?

The other factor is a much larger California that is independent from both Mexico and the US, resulting in a very odd finger of US territory between it and Texas? Could be that after the initial wave of Texan expansion it clashes with the US, possibly with the aid of other powers over the future of California. Seems unlikely, especially since that finger of land stays in American hands but only thing I can think of.

Than it now move therer if you do not have a problem with it.

Wonder, was there ever a American-Mexican war in this universe, looking at it i would say no, but i could be wrong.

So how was California formed than and i also see that the United states has a small strip of New Mexico which separates both California and Texas, makes me wonder if that was done on purpose as maybe they hate each other.

You're right. The US really would have taken more of Canada, probably. From the original timeline:

"Gold is discovered early in California (1844), and the resulting gold rush increases the American and Texan population there,
such that when the Bear Flag Rebellion takes place, sentiment is against annexation, and California remains an
independent republic.

"Consequently, there is never a Mexican-American war. Rather, Polk looks northwest, and the
counterpart of the war with Mexico is a war with Great Britain over Oregon. The US is triumphant,
gaining Oregon and a protectorate over Canada."

I don't remember my thinking now, but I believe the protectorate over Canada expired before 1947. The area between Texas and California is called the "Mormon Strip," and was arrived at by treaty between the US, Mexico, Texas, and California. It's administered by the US, but the treaty says it can't be settled and the area can never become states of any of those countries.

Oh, I assume that the UK was involved in what it considered more important struggles elsewhere, and ceded Canada that way as more trouble that it was worth. Contributing to that attitude is the fact than unlike OTL, three countries instead of one US keep each other from becoming powerful enough to be a real threat to the UK.

Hint: the precise POD takes place at the Alamo.

Close. The defenders lose, but one survives who didn't in OTL.
