More than 40,000 man hours have been spent searching for missing April Jones so far.
As many as 150 expert searchers still scour 60 square kilometres of rugged tree-covered terrain around Machynlleth every day.
Mountains, derelict mines, potholes, lakes, the River Dyfi and the town itself fall within more than 300 search areas.
Every five days search teams are stood down and replaced by an equal number of freshly rested experts eager to start work.
Dyfed Powys Police continue to co-ordinate the massive operation and have vowed to search on into 2013 if needs be.
