The well-prepared bushwalker who vanished without trace
Alex Rosenberg arrived at the popular Edith Falls campground on the tail end of last year's dry season.
Then he vanished without trace.
Moriarty, aged 70, and his dog had sat down for their evening meal together in the tiny town just before Christmas in 2017, and have never been seen again.
Foul play is still the most likely explanation for Moriarty's disappearance, what had befallen Mr Rosenberg?
The NT is not over-imbued with rescue gear but police threw everything at the search, the failed Moriarty sweep gave them recent experience.
Helicopters flew ever widening circles for days, experienced park rangers walked the bush, even police divers were brought in to scour the depths of the tourist-famous clear rock pools.
