in case your interested I have come across a couple Canadian bottles from towns and cities very close to Alaska
there was a bottler in the Yukon , in Whitehorse , called "Whitehorse beverages " , that appeared to operate for some time
also seen a bottle online from Prince Rupert BC , which is a small city in northern BC near the border with southern Alaska , its for "north star " but I don't know anything else about it
search around ebay and online , been unable to find much but Coca Cola was definitely bottled in Alaska , also found an ebay listing for 2 , 7 up bottles that were bottled in Anchorage Alaska
