A mountain search for a hill walker believed to have been missing in Snowdonia since Monday was stopped for the night on Thursday.
A helicopter joins the Snowdonia search for the missing walker
A 40-strong team have been involved in the operation in the Pen-y-Pass area.
Friends of the walker, believed to be from Berkshire, were looking for him when they found his car still in the car park on Thursday lunchtime.
A windscreen voucher suggested it had been parked there since Monday morning. The search will resume on Friday.
Ian Henderson, co-ordinator with the Llanberis Mountain Rescue Team, said on Thursday: "We will meet tonight with the search managers who have been working together and review the information we have got so far".
Aled Taylor, Snowdonia National Park warden, told BBC Radio Cymru that the man, from the Slough area, was believed to have some walking experience but not a great deal.
Search and rescue teams had been split into nine units covering Snowdon with an RAF rescue helicopter covering the more inaccessible parts.
Along with the RAF, the Llanberis and Ogwen Valley mountain rescue and search and rescue dogs association (Sarda) were involved in the operation.
