Raysha Nielsen, 21, killed, when the snowmobile she was riding strikes a tree in the Franklin Basin area of Idaho

Authorities in southeast Idaho are investigating a fatal snowmobile accident over the weekend that claimed the life of a 21-year-old Utah woman who was an up-and-coming racer on the regional snowmobiling circuit. The Franklin County Sheriff said Monday that Raysha Nielsen of Logan was a passenger on a snowmobile that struck a tree Saturday afternoon in the Franklin Basin area east of Franklin. No name or other information has been released in regard to the driver of the snowmobile. The Salt Lake Tribune reports Nielsen was the daughter of Rich Gladfelder, owner of Logan's Renegade Sports. She had become a frequent top-three finisher for Team Polaris in Rocky Mountain Snowmobile Hillclimb Association races. She leaves behind a husband, fellow snowmobile racer Cory Nielsen, and a young son.
