[1] The origin of the contemporary name is obscure, but it may be based on the fact that Mount Solitary is the only mountain in the Jamison Valley.
Along the way is the Ruined Castle, a rock formation on a ridge above the track, and the sealed opening of an old coal mine.
[3] In December 2006, a bush walker, 17-year-old David Iredale, lost the track while on the Katoomba to Wentworth Falls trek with friends.
He made calls to "000" on his mobile phone, but was repeatedly rebuffed by emergency operators because he could not provide a street address to which an ambulance could be dispatched.
He was lost in the bush for twelve days before finally finding some campers in the vicinity of Narrow Neck Plateau.
