Welcome to the Calisota Wiki Edit
Calisota is a fictional U.S. state, created by Carl Barks in his story "The Gilded Man" (Four Color #422). Duckburg is among the cities located there, as well as Goosetown and Mouseton.
Although it has many fictional elements and a variable climate, Calisota is probably roughly equivalent to Northern California. A map in Don Rosa's The Life and Times of Scrooge McDuck portrays Calisota covering the part of California north of Sacramento.
The name is a blend of California and Minnesota—supposedly to allow all kinds of weather or climate in the stories—although Calisota bears very little in common with the latter (a state in the Upper Midwest, far from the ocean coasts).
