Mr. and Mrs. Jean Hersholt (Via), left, and Mr. and Mrs. Leo Carillo (Edith), right, stand in the doorway of Hoot Gibson's house on the grounds of the Saugus Rodeo on the day of the annual event in 1935, April 28. (Actually, Gibson had sold the ranch to Paul Hill in 1934, so it wasn't technically his house any more, although he was probably still living there.)

When Bill Bonelli bought the rodeo grounds in 1939, the home became known as the Bonelli House (or Bonelli Ranch House), and the rodeo was called Bonelli Stadium, later Saugus Speedway. Auto racing was added in the 1940s.

Bonelli's heirs razed the 5,600-square-foot adobe ranch house in February 1988, seven weeks after Santa Clarita became a city, for fear the new city would try to force them to preserve it. In truth, however, it would be another 20 years before the city adopted its first historic preservation ordinance, and it was quickly modified such that it protected only eight (8) properties outside of Heritage Junction-Hart Park, all in Newhall.

Leo Carillo (1881-1961), who descends from an old Spanish California family, was best known for his appearance in the Wallace Beery vehicle, "20 Mule Team" (1940), and for his co-starring role as Pancho in all 157 episodes of the 1950s television series, "The Cisco Kid." A state park and beach in California are named for him. Note: He used the Castillian pronunciation for his name — "ca-reel-yo" ("careeliyo") — not the Mexican pronunciation, "carEEo."

Hersholt (1856-1956) was an actor who made the transition from stage to screen and from Denmark to Hollywood. Often typecast as a villain, he appeared in 1921's "The Four Horsemen of the Apocalypse" with Rudolph Valentino and starred in Erich von Stroheim's "Greed" (1924). He appeared on screen into the 1950s (until death).

The future Saugus Speedway was built originally as a rodeo arena in 1927 by Roy Baker, brother of shoe magnate C.H. Baker.

Roy Baker purchased the 40-acre property east of Bouquet Junction in 1923 for the purpose of breeding and selling show and pleasure horses. To that end he imported saddle brood mares from Kentucky and studded them with a pedigreed, chestnut-colored saddlebred stallion named Peavine McDonald (b. 1910), which sired five pedigreed mares and four pedigreed colts between 1920 and 1936. Baker advertised that he had 2,500 acres of grazing land and also offered training and boarding services for outside horses.

Probably to attract horse buyers to his ranch in faraway Saugus, Baker staged rodeos. Some references suggest he built a 12,000-seat arena in 1924, but this is dubious. (Promoter Bob Anderson organized a local rodeo in 1924, but its exact location is unclear, and it wouldn't have had grandtands.) Anderson did hold the annual rodeo on Baker's property in April 1926. That December, Baker and Anderson started construction on a new stadium, complete with partially covered grandstand seating and a quarter-mile oval track. When it opened May 1, 1927, it seated 18,000 fans, and thousands more had to be turned away for lack of room.

Over the next decade, ownership of the arena would change hands three more times.

As with a majority of the American populace, Baker was hit hard financially by the Great Depression of 1929 and was forced to sell the stadium to cowboy actor Hoot Gibson in 1930. Gibson continued to hold rodeos at the stadium and drew a Hollywood crowd including famous actors such as William S. Hart, Harry Carey, Tom Mix, and John Wayne. He also used the stadium as a movie set or leased it to other companies for film making.

But Gibson felt the effects of the Depression, as well. In September 1933 he appeared in a Los Angeles courtroom and pleaded poverty, saying he had no assets with which to repay a $2,500 loan. He testified that he owned a one-third interest in Hoot Gibson Inc., which owned the Saugus rodeo, and that it was in arrears.

In 1934, Gibson sold the stadium to Paul Hill, owner of the Western Livestock Stockyards, who continued to call it the Hoot Gibson Rodeo. As with his predecessors, however, the stadium brought Hill financial hardship when it was hit by the Great Flood of March 2, 1938. Heavy rains that year caused a river of water to flow down Soledad Canyon and filled the ranch home and arena with mud and debris. As reported in the Los Angeles Times, the "old buildings ... collapsed during the March floods" and the arena was built anew.

Nonetheless, Hill lost the ranch sometime after the April 1938 rodeo. According to Reynolds, the property was repossessed by the bank. In 1939, ownership passed to William Bonelli, and it was renamed Bonelli Stadium.

Bonelli, a professor of economics at Occidental College, continued the annual rodeo tradition for a number of years but introduced auto racing in 1939 on a more frequent schedule; ultimately auto racing became the primary draw and Bonelli renamed the arena Saugus Speedway. Occasional rodeos and circuses continued until at least the late 1960s, auto racing until 1995. The facility was sometimes used for concerts before the grandstands were removed in 2012 (the originals had been replaced in 1955). The venue continues to host an outdoor swap meet.
