Roger Moore said that the Skagway streets were actually a back lot in Burbank, California. The cast were dressed in giant snow boots, fur boots, gloves and parkas, yet the temperature was usually in the eighties.
According to Roger Moore in his autobiography, the fake snow used in production was initially made with gypsum and cornflakes. However, it later included six inch nails and lumps of wood. The crew were allow to wear protective masks, but the actors were not. Moore said that the cast members had to go to the studio nurse at least twice a day to get their eyes flushed out from the dirt and grit.
The Screen Writers Guild went out on strike in January 1960 and did not settle with the major studios until June 1960. After Warners had gone through all existing scripts of "The Alaskans" they began to rework old scripts from their series "Maverick". Hardly more than character names were changed which made the plot very predictable to "Maverick" fans. It is interesting to note that "The Alaskans" went off the air at the same time that the writers settled their strike.
