"North of the Yukon" is a 24-page Disney comics adventure story featuring Scrooge McDuck and his nephews, Donald Duck and Huey, Dewey and Louie.
The character of Barko was inspired by an actual sled dog named Balto, who participated in the 1925 serum run to Nome.
Barks had read an article about Balto in an issue of National Geographic and was inspired to create this character.
Donald is partly to blame after he tries to convince Scrooge that if he does it, he will be paid fifty thousand dollars.
Scrooge refuses, saying that if more people knew that he was the Richest Duck in the World, "every chisler from Cape Town to Nome would be waylaying me!"
Soon after the magazine is published, Scrooge is shocked to see that they extended his story to "ten pages of hogwash" and even calling him "a bashful King Midas".
Scrooge doesn't worry, however; he tells Donald that he has the receipt in his files, proving that he paid Slick in full that same year.
Fortunately for Scrooge, he kept his "big, soft mittens" filled with twenty pounds of gold nuggets.
His hopes of sneaking back into Goldboom unnoticed are foiled after news reporters get wind of the lawsuit.
Dewey sees Slick going for Scrooge's bag (with the receipt inside), and shouts a warning to his uncle.
Scrooge leaps upon the would-be thief, and seeing that it's actually Slick in disguise, the two fight.
Donald tries to convince his uncle that the newsmen could help him, but Scrooge refuses, seeing that this was meant to be a race between Slick and himself, "with the only rules of the Arctic Law of Club and Fang."
Desperate to help their uncle, the boys stop by an Inuit village to see the local Junior Woodchucks.
As the sled sinks through the ice, Scrooge cuts the team free, and they make it for dry land.
Before he can rip it and steal Scrooge's great fortune, news reporters show up, taking his photo for the court to see.
