March 2, 1935–March 5, 2019

Dean Helms of Newcastle, Wyo., passed away Tuesday, March 5, 2019, at Rapid City Regional Hospital; he was 84.  

Dean was born on March 2, 1935, in Los Angeles, Calif., to Leonard and Mabel (Clark) Helms. While growing up, his family moved to Texas and worked in the oil industry for many years. He graduated high school in Dallas, Texas, and then enlisted in the United States Marine Corps on March 6, 1953, and was honorably discharged on March 5, 1956.  

The family relocated to Hot Springs, S.D., where Dean took over the family drilling business after his father was killed in an accident in the early 1960s. He was married to Gwen Nienaber, and from that marriage two children were born, Darby (Larralde) Helms and LA Helms. The family later moved to Newcastle. During his time in Newcastle, he had several businesses, including a machine shop and a bar on Main Street.  

Dean was an avid outdoorsman. He enjoyed hunting, fishing, camping and taking long drives down the bumpy old back roads. He was a big fan of trips to Deadwood, S.D., and a huge sports fan who spent much of his time watching football, baseball and basketball, rooting for his favorite teams.  

He is preceded in death by his parents; brother, Thad Helms; son, LA Helms; and his daughter, Darby Larralde.  

Dean is survived by five loving grandchildren, JW (Cheryl) Vickers of Buffalo, Wyo., Jamie (Samuel) Van Norman of Belle Fourche, S.D., Michael (Bridget) Helms of Sundance, Wyo., Joseph Helms and Jesse Larralde, both of Gillette; and five great-grandchildren, Chelsea, Sawyer, Lane, Jaxon and Maxwell.  

A memorial for Dean will be held (and announced) later in the spring when the weather is more cooperative. His final resting place will be Black Hills National Cemetery where he will be laid to rest with military honors.  

In lieu of flowers, cards/letters/memorials can be sent to 215 7th Ave., Belle Fourche, SD 57717.
