Seth Rasmuson

Seth Dean Rasmuson was born in Rapid City, South Dakota on February 22, 2001, to Curtis and Jennifer Rasmuson. He is the second child of five sons. Seth moved to Buffalo, Wyoming with his family in September of 2001. He loved spending time in the Bighorn Mountains fishing and hunting with his Dad, brothers, and dear friend Augie Wagner. He had a wonderful childhood surrounded by his four brothers and friends. He enjoyed playing baseball and hockey. Seth knew at a young age he wanted to serve his country as a U.S. Marine. He graduated from Buffalo High School a semester early and went to boot camp after his 18th birthday. Seth graduated from boot camp on June 7, 2019. He then went on to become a tiltrotor Crew Chief after another 15 months of training; including Survival, Evade, Resist, and Escape (SERE) training in Maine.

On May 18, 2020, Seth married the love of his life and childhood sweetheart, Avery Burtenshaw. Avery was Seth’s rock during his military career; always supporting him, encouraging him, and being an incredible mother to their sweet son, Reed James Rasmuson, who was born in October of 2021. Seth’s first duty station was at Camp Pendleton where he and Avery began their married lives together. He reported to the Purple Foxes, Marine Air Group 39 starting his career as an Osprey Crew Chief. He was deployed in April 2021 for six months to the Middle East, earning his combat wings while serving in Saudi Arabia and Djibouti. Seth and Avery had a little over a year left in the Marine Corps at the time of Seth’s death before beginning their much-anticipated civilian life.

Seth is survived by his wife, Avery (Burtenshaw) Rasmuson; son, Reed Rasmuson; parents, Curtis and Jennifer (Whatley) Rasmuson; brothers, Blaine (Emma), Trevor, Ryan, and Cole Rasmuson; dearest friend Augie T. Wagner; nieces, Ava and Hazel Rasmuson; grandfathers, Dean Rasmuson and Loyd Whatley; several aunts, uncles, and cousins. He is preceded in death by his grandmothers, Marlene (Hansen) Rasmuson and Viola N. (Gilbert) Whatley.
