Steve Ridd, who used to work in corporate IT, has written an extensive blog about the death of corporate IT salesman Gary Tweddle. His conclusion is that the effects of work induced stress, plus alcohol and cocaine caused Gary to think that lights visible in the dark on the other side of the valley were at the end of a road or track and that he could reach them by running there, when in fact they were separated by cliff faces on both sides of a chasm. Gary’s disappearance led to the second largest search in local history (about 1,000 people including myself searched from Wentworth Falls to Katoomba for weeks). Steve hasn’t finished editing the blog but you can read it here:

Steve now works as a local tourist guide and he is extremely critical of the Upper Blue Mountains Bushwalking club culture that he says led to the deaths of the two women in Wollangambe canyon. He also says that a canyon grading system like that which exists elsewhere should be introduced in the Blue Mountains.
