Mr Walsh, who climbed the mountain as often as twice weekly, is believed to have made his final ascent on Thursday last sustaining a serious injury in the process.
His body was found on Friday. It is believed he lay overnight near the oratory on the summit. A group of other climbers found around 11.30 am on Friday and raised the alarm.
A coastguard helicopter from Sligo was tasked but was unable to land due to difficult weather conditions. But the chopper did manage to lower a paramedic who pronounced the man dead at the scene.
The body was taken from the mountain later by a team from Mayo Mountain Rescue and transferred by hearse to Mayo General Hospital in Castlebar for a post mortem examination.
Mr. Walsh, a single man, who loved at Derrygolan, Tullamore, was described by the parish priest of Tullamore, Monsignor Sean Heaney yesterday as “deeply religious”.
