Karl Gaskell, 33, visited the “extremely remote” site in the early morning hours of August 23.
A Bolton coroner’s court inquest heard he had texted his father Anthony Gaskell and left letters with details of his location.
Mr. Gaskell reported his son missing and the police used the What Three Words app to find Karl next to a man-made hut.
He could not be resuscitated and was pronounced dead shortly after.
An autopsy revealed he had died from suspension by ligature. There were no drugs or alcohol in his body.
The investigation learned that Karl, who lived in Abram with his father, loved bushcraft and went camping in the Lake District, enjoyed spending time with his dog and making knives.
He had no diagnosed mental health issues but was severely affected by his mother’s death in 2016.
While he seemed confident, he had concerns about his image and it was affecting his relationships.
He had also assisted the police in an investigation, although the details of that investigation were not disclosed in court.
Mr Gaskell saw him briefly at his home on the evening of August 22, but inquiries learned he hadn’t noticed if he was more withdrawn than usual.
He heard Karl’s alarm for work at 5:30 a.m. the next morning and his car pulled away shortly after.
But at 8:30 am, he saw a text from Karl which worried him and he found handwritten notes in his room, which included his location using What Three Words.
He alerted the police, who found Karl in the hut.
Senior Coroner Timothy Brennand recorded that Karl had committed suicide, after learning the whereabouts he was found and notes he left to express his intention.
He said: “Part of the tragedy the family understandably expresses is that if Karl had in fact chosen to look to them, they would have been nothing but supports and encouragement and if that s ‘was produced, it could have meant that Karl could have been guided into a more positive frame of mind.
