Police are appealing for sightings of a walker whose car was found in the Yorkshire Dales.
Kathryn Summersgill was reported missing on Monday and police are concerned for her safety as bad weather has hit the area.
The 62-year-old was seen leaving her Renault Clio in Buckden car park at 9.25am on Friday and was believed to be heading for a walk in the area.
North Yorkshire Police said: “Kathryn recently moved into the local area from Worcester and she also has links with the Ilkley area of West Yorkshire.
“It’s understood that Kathryn is a keen walker and is known to visit the Yorkshire Dales regularly, so has a good knowledge of the local area. However with the recent weather and temperatures, police are becoming increasing concerned for her safety.”
Officers have asked walkers and other outdoor enthusiasts to be on the lookout for her. Searches are continuing, they said.
Police said Ms Summersgill is known to walk three routes from Buckden: Cray Gill, Yockenthwaite and Langstrothdale; Redmire Woods along the River Wharfe to Starbotton; and Rakes Wood to Buckden Gill lead mine and then to Starbotton.
Anyone who was in the area on Friday or over the weekend and who might have seen Ms Summersgill walking alone is asked to contact police on 101 and speak to the force control room, quoting incident number 12160211085.
