Onni Raassina, a 28-year-old man from Finland, was last seen March 5, 2025, after arriving at Salt Lake City International Airport. He planned to visit the Moon Lake area in Duchesne County to explore the Uinta Mountains and was reportedly driven toward Moon Lake Lodge by a yellow cab. It is unclear whether he ever reached his intended destination.

Onni’s phone last pinged in the Moon Lake area, roughly 150 miles east of Salt Lake City. He was reported missing by family on March 17, 2025, after nearly two weeks without contact. Authorities say he did not appear to have appropriate equipment for harsh winter conditions, the campground is closed for the season, and searchers have found no further clues. He is described as white, short blonde hair, blue eyes, 5 feet 9 inches, 165 pounds, last seen in a gray hoodie, black jeans and carrying a black backpack.

The case is classified as endangered missing and investigators are asking anyone with information to contact the Duchesne County Sheriff’s Office. Did anyone in the Moon Lake or Uinta Mountains area see a traveler matching Onni’s description in early March?
