"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 Doctor Joseph Romig.
In the episode, Indiana Jones would have been involved in an expedition with an American anthropologist, his professor, to study Eskimos in a region east of Nome near the Arctic Circle. There, Jones and his professor would have meet Nellie Cashman and Doctor Joseph Romig. Indy would meet and get to know the villagers, and would have learned about sledding and the care of the dog team, going on a hunt with them, and learning about their customs. The villagers would have been stricken by a contagious disease with the serum having to be rushed to them by dog sled so that they could be inoculated.
