After an apparent try to hike a 12, 326-foot mountain, an engineer from the Bay Area was discovered lifeless in a Wyoming national park last weekend.

The Grand Teton National Park rangers on Monday released a statement identifying the victim as 42-year-old Hitoshi Onoe, a Japanese national who resides and works in San Jose.

His body was recovered by park rangers on Saturday on Teewinot Mountain’s Black Chimney climbing route base.

According to a Grand Teton National Park spokesperson’s statement to SFGATE, the victim probably died a day before he was found by park rangers.

Onoe has served as an information technology engineer, as reported by Bay Area News Group. He was living alone at an Airbnb in Jackson, Wyo.

The engineer was believed to pursue climbing Teewinot Mountain alone using the East Face route, a marked map found on his belongings show. Park rangers described the route as difficult for “route finding.”

While the East Face is categorized as a Class 4 hike and is a famed ski destination, Black Chimney, where the victim was found, is designated as a Class 5. The Bay Area News Group reported that one attempting to climb the route needs to have ample hiking experience and to secure protection took.

The Japanese consulate is already in the process of informing the engineer’s family in Japan for next-of-kin notice, park officials said.
