Who Is Mark Slade?
You probably know him as Blue Cannon, the blond, blue-eyed son of ranch patriarch John Cannon on The High Chaparral. He won the role in 1966 after an impromptu audition with the show's creator, David Dortort.
Before that, he'd already built a following playing seasick radioman Patrick Hollis on the NBC sitcom The Wackiest Ship in the Army (1965–66). The High Chaparral is what made him a household name in Western television.
Mark Slade's Age and Early Life
Slade was born in Salem, Massachusetts, the son of Elinor Van Blarcom and William A. Slade Jr., a Boston businessman and watercolor artist. His parents divorced when he was 13.
- His stepfather, Esmond R. Crowley Jr., became a major influence on his life.
- He enrolled at Worcester Academy in 1956 intending to become a painter.
- He turned 87 on May 1, 2026.
That last detail — art school before acting school — matters. It explains why he eventually returned to painting as his primary creative outlet.
How Tall Is Mark Slade?
Several fan and bio sites list his height as 5'10" (178 cm). None of them cite where that number originally came from.
It's likely lifted from an old fan-club measurement or a since-deleted database entry and then copied site to site for years. Treat it as commonly repeated, not verified.
Mark Slade's Career
The High Chaparral and Billy "Blue" Cannon
The High Chaparral ran from 1967 to 1971, and Slade's character was central to the ranch-family drama at its core. He also guest-starred as Jud Rikeman on Bonanza the same year he landed the Blue Cannon role.
According to his IMDb biography, he received several period acting honors, including a Western Heritage Award, and was made an honorary life member of the Navajo Nation for his portrayal of Native American storylines with sympathy and accuracy.
Life After The High Chaparral
Slade didn't disappear when the show ended — he shifted behind the camera. He wrote and starred in the 1975 TV episode "Cliffy," which reportedly earned national writing awards and a commendation from the White House, per his IMDb profile.
He also appeared in guest roles on other Western-era staples:
- Gunsmoke
- The Virginian
- The Big Valley
- Branded
- Voyage to the Bottom of the Sea
Mark Slade the Artist and Author
This is the part most competing pages skip entirely. Slade returned to his original ambition — painting — and now sells original oils, mixed-media work, and photography through his own site, marksladestudio.com.
He's also published written work, continuing the storytelling instinct that shaped his acting and directing career.

Mark Slade's Personal Life
