The search for missing five-year-old April Jones is drawing to a close and is expected to end in a few weeks.
Officers from around the UK have been searching for the little girl since she disappeared from near her home in Machynlleth, Powys, in October.
In a statement Dyfed-Powys Police said: "It has been a massive search operation where an area of 60 kilometres square (23 square miles) has been searched including and have over 300 specific search areas.
"The terrain is extremely challenging. The mountains, gorges, streams and waterfalls in the area mean extra care has to be taken and specialist safety equipment has to be worn.
"The force made a commitment to search until all viable lines of enquiry were complete."
Officers confirmed the search would stop over Easter but that during the rest of April they would search "specific areas of land with a view to all search areas identified being completed by the end of April".
Searches of specific areas of land will continue but they are expected to be completed at the end of next month.
Mark Bridger, 47, denies abducting and murdering April as well as intending to pervert the course of justice. He is due to stand trial at Mold Crown Court on 29 April.
April's disappearance sparked one of the largest police searches in UK history.
