Andrew Callesen “Cal” Thybo, 61, left this earth to go on to ride fences for the biggest spread around on June 27, 2020. Cal was a cowboy, rancher, husband, father, brother, and dear friend.
He was born December 12, 1958, in Belle Fourche, SD, to Arlo James “Buck” Thybo and Karen (Steele) Thybo. He spent his youth on the family ranch south of Reva, SD. He attended country school at the Rock Ranch School just a couple miles from home. He and his brother, Jimmy, spent their days riding in the Slim Buttes, riding calves, yearlings, and whatever else they could capture. He attended eighth grade in Nisland, SD, and high school in Spearfish, SD, where he graduated in 1977. He started riding saddle broncs as a freshman in high school. He continued to ride saddle broncs for several years after school.
Cal worked for the Crago ranches, first for Walt Crago, then later Vince Crago. He worked on the Kudlock ranch for three years before moving to the Bar H Ranch at Reva. The Bar H was special to him because it was an original Thybo family ranch. He managed the Bar H for 21 years, from 1999 until his passing. He worked hard to improve the cows and the grass on the place. He really enjoyed helping the neighbors; he would drop anything when someone needed help. Many of his favorite days were spent working with the neighbor crew. He loved cowboying and spent a lot of long days on horseback. Cal was also a silversmith, accomplished at making bits and spurs. His grandson, Tregg, put a twinkle in his eye.
Cal is survived by the love of his life, Gail Thybo; children, Teresa Thybo, Tyrel (Jamie) Thybo, and Ashley Thybo; his grandson, Tregg Mitchell Thybo; sister, Kay Thybo Kornemann; brother, Jimmy (Rhonda) Thybo; sister, Oddette Thybo Lambert; aunt, Marie (Jimmie) Donohue; and many cousins, nieces, and nephews.
A prayer service will be held at 6:00 p.m. Wednesday, July 1, at Kinkade Funeral Chapel in Sturgis.
Funeral services will be at 11:00 a.m. Thursday, July 2, 2020, at Besler’s Cadillac Ranch in St. Onge. Interment will be at Pine Slope Cemetery in Belle Fourche, next to his grandpa, James, and grandma, Mary Thybo.

I did not expect a rembrance that would hark back to my early life in South Dakota. I was searching Google maps to take me back to the time that I spent erecting barb wire fence in the Slim Buttes in North Western South Dakota in about 1966. At that time I worked for my uncles construction company, Rounds Construction, who had a contract to build about 40 miles of fence through the Thybo Ranch. I stayed at Buck Thybo's bunk house and enjoyed dinner with them every evening and certainly knew Cal when he was very young. Buck showed me how he was training Cal to be a real cowboy, in fact a real rodeo cowboy at that time. And part of the tuteledge was learning how to chew tobacco as well.

I am very sad to hear of his passing. His family was always very kind to me and I still relish the time I spent on their range. At the time Buck told me that his parents had only installed indoor plumbing a few years ago. I very much treasured Cals life story as I only knew Chapter 1. Cal was in every real sense a real cowboy and he will missed on the range.
