I don't have first-hand stories on-hand about the role of the post office in Alaska, though I'd love to read them! I did find this blog post that explains some of the ways USPS supports rural Alaskan communities: https://blog.evankalish.com/2017/02/the-last-frontier-alaska-by-post-office.html
I also found this USPS report on the Alaska ByPass from 2011 interesting (screenshots attached). not surprisingly, found it was benefiting private interests on the backs of USPS.
And a nice piece in the Guardian: https://www.theguardian.com/world/2014/jul/01/us-postal-service-alaska-bypass
