Synopsis:
Scrooge is having trouble with his bad memory but after a visit to the doctor he recalls a huge gold deposit he once left behind in Alaska.

Comments:
Alaska was Barks' favourite location outside the Duckburg area (as measured by the number of stories in which the ducks go to any particular state). In this story he has strewn the pages with both real location names (such as Chillfoot Pass, Dawson, Klondike, Skagway, White Agony Creek, Whitehorse) and invented ones (such as Bearflanks, Chillblain, Chillifoot, Frozenjaw River, Goldboom).

Other stories:
FC0062 Frozen Gold, FC0256 Luck of the North, U$13 'Mush!' (1-pager), U$19 The Mines of King Solomon, U$35 The Golden Nugget Boat, U$59 North of the Yukon.

Synopsis:
Scrooge lacks excitement in his life so he follows Donald and the nephews to the desert in order to collect arrowheads. They also find seven golden cities...

Comments:
The last half of the story takes place in Arizona, although Barks never mentions it. The deduction is pretty straightforward: The ducks start out at the Californian border (see California), whereupon they cross the Colorado River meaning that they wind up in Arizona.

Other stories:
U$19 The Mines of King Solomon (one panel), WDCS058 'Grand Canyon', WDCS246 Lost Frontier.

Synopsis:
Following a traffic accident Donald and the nephews feel as they have travelled back a hundred years in time. They visit a Spanish ranchero and gold is found.

Comments:
In a great number of 10-pagers Barks would draw locales that were very familiar to him because he lived in the same sort of surroundings. Even an adventure story like this was filled with locales from his own 'backyard'. In the panel he gave us his rendering of Sutter's Fort.

Other stories:
KG Donald Duck Tells About Kites - version 1 and 2 (giveaways for two local electricity companies), U$07 'The Cibola Story' (the first half of the story takes place in several named places in South California), WDCS245 Sitting High.

Synopsis:
Donald and the nephews travel to an unexplored swamp just to show their grit. They meet a strange tribe and decide to bring one of the inhabitants back home to prove that they have been in the area.

Comments:
The swamp area is The Everglades in Florida. The ducks revisited the area twice (without encountering the strange inhabitants again)...

Other stories:
KG Donald Duck Tells About Kites - version 3 (giveaway for a local electricity company), U$32 That's No Fable!, WDCS147 'Gladstone's Blackmail Dinner'.

Synopsis:
Scrooge buys a volcanic island where he intends to hide his money. But The Beagle Boys learn about his plans!

Comments:
The last half of the story takes place in the Hawaiian islands, where Barks' wife Garé was born and raised, thus she knew a great deal about the islands' history, tales, and special flora. Her valuable insight especially in the latter subject helped Barks form the atmospheric backgrounds for the story.

Other stories:
No.

Synopsis:
The Beagle Boys construct a giant chopping machine to open the Money Bin. Scrooge mails his money to the far woods but the crooks are at his heels...

Comments:
Some of the action takes place on the outskirts of the fictitious town Talltree.

Other stories:
No.

Synopsis:
Scrooge tosses a coin across the Potomac River in an attempt to catch it again before it lands on the other side!

Comments:
This is a 1-pager! The reference to Maryland can be deduced by the fact that Scrooge is standing near Mount Vernon, President George Washington's Virginian plantation on the banks of the Potomac River (see Virginia). When Scrooge enters the river and soon after lands on the other side he is in Maryland.

Other stories:
No.

Synopsis:
Scrooge participates in a steamboat race in which two river captains are fighting over a southern mansion on the Mississippi River.

Comments:
The ducks start the race from Natchez. In U$GTD 'The Fantastic River Race' they were also racing on the same river, but no clear references as for their precise whereabouts are mentioned.

Other stories:
No.

Synopsis:
The nephews draw a treasure map for a game they intend to play. Donald finds the bogus map...

Comments:
The ducks wind up in a desolate military target area in the middle of nowhere.

Other stories:
No.

Synopsis:
The nephews are practicing high wire walking and Donald just has to top them. He heads for Niagara Falls!

Comments:
The state's best known, natural sight is this series of falls that border Canada. When Barks made this story he simply had to refer to them by their real name, because that kind of falls would not be plausible even in Calisota!

Other stories:
WDCS142 'The Fool-proof Vacation' where the ducks are on vacation on Lake Erie, but Donald takes a dive down the falls.

Synopsis:
Donald becomes the owner of a houseboat and travels down the river with his nephews. But the river is haunted by a sea serpent.

Comments:
The ducks travel to the fictitious town of Floodout.

Other stories:
No.

Synopsis:
Donald travels to British Guiana in order to trace down a valuable stamp and he finds it on an undelivered letter. But it has to be delivered first...

Comments:
The ducks travel to the fictitious town of Webfoot in order to trace the adressee of the letter, Miss Susiebelle Swan, 10 Quack Road.

Other stories:
No.

Synopsis:
Scrooge tosses a coin across the Potomac River in an attempt to catch it again before it lands on the other side!

Comments:
This is a 1-pager! The reference to Virginia is plain to see from the sign speaking of an old legend about young George Washington who once was supposed to have thrown a silver dollar across the river (which bordered his estate, Mount Vernon). This would have called for a very strong arm, though, because the river at that point is about 1 mile (1,6 kilometers) wide! (See also Maryland.)

Other stories:
No.

Synopsis:
Donald is checking on how to catch the biggest salmon in a contest in order to win a Snobmobile. But Gladstone is checking in, too...

Comments:
In the opening splash panel we are shown Puget Sound, where the entire story takes place.

Other stories:
WDCS202 'The Rainmaker Story' is also situated in Washington State. Donald speaks of one of the area's Indian tribes, the Yakimas (in Barks' version they became the Kakimaws), and he also took the unprecedented step of acknowledging an old legend of theirs in the splash panel of the story!

The page can by no means be complete for a number of reasons:

A: On their many car trips outside Calisota the ducks must have passed several state lines. Example: This must have happened in WDCS049 'High Wire Artist', when they drove to Niagara Falls.
B: Some places can only be identified partly. Example: In WDCS142 'Houseboat Vacation' the ducks sail on Lake Erie. Trouble is that the lake borders Michigan, New York, Ohio, and Pennsylvania, and we do not know exactly which borders the ducks were near.
C: Some places are only shown or mentioned in one panel of a certain story. Example: U$14 A Square Inch of Land where Barks mentions the ducks' trips to Alabama, Florida, Idaho, Indiana, South Carolina, and Tennessee. Furthermore, it is mentioned that the ducks drive to 'the Panhandle' which might indicate additional states such as Oklahoma, Texas, and perhaps even West Virginia (known as the Panhandle State). Considering that the ducks after a one-day car trip wind up at a place with oil and prairie dogs Texas seems plausible.
D: Some of the 10-pagers contain hidden pointers from Barks' personal life, but they are not easily read. Example: WDCS192 'The Kingfisher Story' takes place in Washington where his daughter Peggy and her husband managed a salmon hatchery for many years.

So, if you are an American citizen and miss the mentioning of your home state, don't despair;
the ducks might have been there after all...
