Why is it so hard to find election data for Alaska?

[minionofmidas]

Alaska does not compile election results by boroughs, but by state house districts. Nor does it compile early / absentee votes by originating precinct. That is the answer to your question.

And the description in the second sentence is far too simplistic.

Is Alaksa all Vote by Mail?

My understanding is that in the remote rural regions it is, tho people there still have the option to make the trek into a town that has a polling station.

The population of the really remote rural regions of Alaska live in small-but-not-minuscule settlements isolated from each other. They have little reason to vote by mail, and don't do so by nationally remarkable rates.
There are some areas of Alaska however that are effectively vote-by-mail.

There really weren't any, at all, until 2012. The new map is a lot worse.

The Natives did.

Just because they always voted for Democrats in the State House doesn't mean they voted for Democratic Presidents - or rather, doesn't mean they did so by margins at all comparable to the Lower 48.
Alaska Natives, Miami Cubans and California Vietnamese are Romney's lost triplets.
