James “Butch” Harland Mayfield, 84, of Playas, New Mexico, passed away on Saturday, October 10, 2026, following a seven-year battle with cancer.

Butch is survived by his wife, Amanda Mayfield; his daughters, Leann Saunders (John) and Melinda Birkeland; and his six grandchildren, Kenneth Saunders, Hannah Saunders, Kathryn Saunders, Payson Birkeland, Riley Birkeland and Cain Birkeland. He is also survived by Amanda’s daughters, Victoria Johnson and Erica Valdez.

Born December 27, 1941, in Durango, Colorado, Butch was the son of James Fletcher Mayfield and Annie Modene Mayfield. Affectionately nicknamed “Butch” by his parents, he grew up in southwestern Colorado, where he developed a lifelong love of ranching, horses and cattle.

Butch graduated from Ignacio High School in 1959, where he played football and basketball, ran track, participated in the Science Club and served as president of the Future Farmers of America (FFA), earning FFA state judging awards. His classmates voted him both “Most Versatile” and “Best Dressed” in his senior class.

He earned a Bachelor of Arts degree in Mathematics from Fort Lewis College in 1965 and a Bachelor of Science degree in Civil Engineering from Colorado State University in 1967. He continued his education while serving in the military, earning a master’s degree in Mathematics from American University in Washington, D.C., in 1969.

In November 1967, Butch was drafted into the United States Army and completed basic training at Fort Bliss in El Paso, Texas. Recognized for his exceptional mathematical abilities, he was assigned to the Combat Analysis Group at the Pentagon, where he served from March 1968 through September 1969, supporting the Joint Chiefs of Staff. For his distinguished military service, he was awarded the Joint Service Commendation Medal.

Butch began his professional engineering career with the Colorado Highway Department in 1963, working intermittently while completing his education and military service. He ultimately rose to the position of Head District Construction Engineer, overseeing district construction operations. He remained with the department until 1980, when he chose to pursue his lifelong passion for ranching full-time.

Following his military service, Butch began building his cattle herd while living in the Ignacio and Bayfield areas of Colorado, with cattle operations extending into Pagosa Springs and northern New Mexico. An accomplished horseman, he raised quality American Quarter Horses that he used extensively in his ranching operations.

In 1986, Butch sold his Colorado ranching operations and relocated to southwestern New Mexico, settling in Playas, where he continued ranching for the remainder of his life. Through decades of dedication, determination and hard work, he built a respected cattle operation and established lasting relationships throughout the livestock industry.

A progressive and forward-thinking cattleman, Butch recognized early the opportunities that emerging livestock marketing technologies could provide to ranchers. He worked with Satellite Cattle Exchange, a pioneer in video livestock marketing, before joining Superior Livestock Auction in 1993 as one of its original video marketing representatives.

For more than three decades, Butch devoted himself to serving cattle producers throughout the Southwest. He took great pride in helping his customers reach new markets, participate in value-added marketing programs and secure competitive opportunities for their cattle. His commitment to his customers and extensive knowledge of the cattle industry helped grow Superior Livestock Auction’s Southwestern Region and earned him numerous awards and professional recognition.

In April 1996, Butch married Amanda Mayfield in Silver City, New Mexico. Together, they shared a life centered around ranching and the livestock industry. Amanda worked alongside Butch in his Superior Livestock Auction business, where he shared his extensive knowledge and experience, helping her develop her own expertise in cattle marketing. They worked closely together with his customers until his death.

Among his many ranching accomplishments, Mayfield Ranches, LLC, was honored as the 2018 Commercial Cattleman of the Year by the American-International Charolais Association, recognizing the operation’s commitment to quality cattle and progressive breeding practices.

Beyond his professional achievements, Butch was a talented lead guitarist, bluegrass musician and singer. Music was an important part of the Mayfield family tradition, and annual family reunions often featured three days of bluegrass music played by generations of family members. A devoted enthusiast, Butch maintained a nearly complete collection of Bluegrass Unlimited magazine, missing only its inaugural issue, and faithfully read each edition from cover to cover.

One of his most memorable stories dated back to his military service in Washington, D.C., when legendary bluegrass musician Bill Monroe invited him to join him on the road. Although Butch chose not to pursue the opportunity, he often reflected on it as one of life’s great “what ifs.”

As a father, Butch instilled in his daughters the values of independence, determination and a strong work ethic. A devoted “girl dad” long before the term became popular, he raised his daughters with the same expectations, opportunities and responsibilities he would have given sons. He taught them to be capable, self-reliant and unafraid of hard work, lessons that would shape their lives and remain an enduring part of his legacy.

Butch was known for his exceptional intelligence, tireless work ethic, determination and unwavering commitment to achieving his goals. Whether working cattle, serving his customers, or playing music, he approached life with passion and purpose. His accomplishments were many, but his greatest legacy will be the example he set through his perseverance, integrity and dedication to the things he loved.

He will be deeply missed by his family, friends, fellow cattlemen and the many people whose lives he touched throughout his 84 years.
