Challenge of the Yukon

 Challenge of the Yukon was a radio series that began on Detroit's station WXYZ (as had The Lone Ranger and The Green Hornet), and an example of a Northern genre story. The series was first heard on February 3, 1938.

The title changed from Challenge of the Yukon to Sergeant Preston of the Yukon in November 1951, and remained under that name through the end of the series and into television. The program was an adventure series about Sergeant William Preston of the North-West Mounted Police and his lead sled dog, Yukon King, as they fought evildoers in the Northern wilderness during the Gold Rush of the 1890s. Preston, according to radio historian Jim Harmon, first joined the Mounties to capture his father's killer, and when he was successful he was promoted to sergeant. Preston worked under the command of Inspector Conrad, and in the early years was often assisted by a French-Canadian guide named Pierre.

 Preston's staunchest ally, who was arguably the true star of the show and indeed often did more work than he did, was the brave Alaskan husky, Yukon King. Typical plots involved the pair helping injured trappers, tracking down smugglers, or saving cabin dwellers from wolverines. Sergeant Preston's faithful steed was Rex, used primarily in the summer months, but generally Yukon King and his dog team were the key mode of transportation (as signaled by Preston's cry of "On, King! On, you huskies!)."

There is some confusion regarding King's actual breed. The writers seemed to use malamute and husky interchangeably. At least once, Preston answered "malamute" to the question from another character. In one radio episode Preston indicates King's mother had been a wolf, which would make him a wolfdog. In the early radio shows, the cry of "On, you huskies!" would alternate with "On, you malamutes" from show to show.

The theme music was Emil von Reznicek's overture to Donna Diana a now long-forgotten opera, though the overture remains a concert staple to this day. The show's episodes ended with the official pronouncement, Well, King, this case is closed.


Following the success of Lone Ranger and Green Hornet, George W. Trendle, the station owner, asked for a similar adventure show, but with a dog as the hero. According to WXYZ staffer Dick Osgood, in his history of the station, Trendle insisted that it not be "a dog like Lassie because.. this must be an action story. It had to be a working dog." Writer Tom Dougall, who had been influenced by the poems of Robert W. Service, naturally chose a Husky. The dog was originally called Mogo, but after criticism by Trendle, Dougall re-christened the canine King. Dougall likewise created Sgt. Preston and the French-Canadian guide. Fran Striker, who wrote for The Lone Ranger, also contributed scripts.

However, Trendle's criticism of Dougall may have had another reason behind it. Shortly before the two Trendle series aired (Lone Ranger and Challenge of the Yukon), popular author Zane Grey had a book in circulation (Lone Star Ranger) about a Texas Ranger like the Lone Ranger and a comic book series in circulation (King of the Royal Mounted) about the adventures of Sgt. King, a Royal Canadian Mounted Policeman like Sgt. Preston. It could be that Trendle borrowed both ideas from Grey's work and wanted to retain the name "King" as a tribute to Grey, who died after a long illness one year following the first airing of Challenge of the Yukon.


Challenge of the Yukon began as a 15-minute serial, airing locally from 1938 until May 28, 1947. Shortly thereafter, the program acquired a sponsor, Quaker Oats, and the series, in a half-hour format, moved to the networks. The program aired on ABC from June 12, 1947, to December 30, 1949. It was then heard on The Mutual Broadcasting System from January 2, 1950, through the final broadcast on June 9, 1955. In November 1951, the title changed to Sergeant Preston of the Yukon.

 Radio cast:

  Sgt. Preston – The part of Sgt. Preston was played by different actors over the course of the long run. Jay Michael, who had often played villain Butch Cavendish on The Lone Ranger, originated the role, and played the brave Mountie from 1938 through the mid 1940s. Former movie actor Paul Sutton took over the role, followed briefly by Brace Beemer when The Lone Ranger ended in 1954. Sutton took over again, however, by the time of the final broadcast.

Yukon King – The barks, whines, and howls of Yukon King were supplied by one of the station's sound effects men, Dewey Cole, and following Cole's death, by actor Ted Johnstone.

Narrator and supporting players – The original announcer/narrator was Bob Hite, also a narrator for the Lone Ranger, Green Hornet and The Shadow. Hite was replaced by former star Jay Michael when Sutton took over. Lone Ranger narrator Fred Foy also filled the role from time to time. John Todd was heard occasionally as Inspector Conrad, and Frank Russell played Pierre. Episodic performers came from the same talent pool as the other WXYZ shows.

From 1951 to 1958 Dell Comics published 29 issues of Sergeant Preston of the Yukon. The first four issues appeared bi-annually, then quarterly, in the weekly catch-all series, Four Color Comics (#344,373,397,419), then assumed its own numbering with issue #5, most-often as a quarterly but also bi-monthly. All issues were written by Gaylord Du Bois (creator of Turok), and illustrated by Alberto Giolitti (best known as the long-time illustrator of Turok). The Dell comic book covers were paintings portraying drama or action, featuring Yukon King and Sergeant Preston in exciting scenes. Once the Sergeant Preston of the Yukon television series premiered, the comic book featured photo covers of the TV series star in character as Sergeant Preston.


 In 1955, the same year the radio show ended, Sergeant Preston of the Yukon premiered as a television series. Richard Simmons starred as Sgt. Preston, and was supported by Yukon King and Rex, now played by real animals. The dog cast as King was not a husky, however, but a large Alaskan Malamute. Charles Livingstone, who had worked on the radio version, directed several episodes. Though no plotlines seem to have been re-used from the radio show, they were generally built upon the same themes. The same few buildings were regularly seen as part of many settlements in the shows. The additional visual component of the snowy Yukon, however, did give the television version a different feel but like all such films when filmed on a stage set, the frosty breath of people in Arctic conditions could not be simulated. Generally, however, there was an outdoor feel though a few times shadows on the skyline could be seen. Genuine outdoor scenes were added to give the show some reality though the viewer could not help but notice a sameness to them as they were all filmed in the same area and reused at times.

Mainly filmed at Ashcroft, Colorado, the series was telecast on CBS from September 29, 1955, to September 25, 1958. The first two seasons were produced by Trendle-Campbell-Meurer, and the show was broadcast in the same time slot as ABC's The Lone Ranger. In its last season, Sergeant Preston of the Yukon was purchased and produced by the Jack Wrather Corporation.

In 1955, the Quaker Oats company gave away land in the Klondike as part of a promotional tie-in with the television show. Genuine deeds each to one square inch of a lot in Yukon Territory, issued by Klondike Big Inch Land Co. Inc., were inserted into Quaker's Puffed Wheat and Puffed Rice cereal boxes.
