"Alaska, June 1921" was an un-produced episode of The Young Indiana Jones Chronicles, which would have been part of the third season of the series. The subject of the episode would have been anthropology, and the historical figures Indy would encounter were Nellie Cashman and Dr. Joseph Romig.
In the episode, Indy studies a group of eskimos with one of his professors. After a contagious disease is discovered among the group, medicine has to be brought by dog sled. The events of this episode are possibly foreshadowed in Young Indiana Jones: Travels with Father.
