Scarborough and Ryedale Mountain Rescue Team was called out almost 60 times in 2014 in one of its busiest years on record.
The team, which covers a patch of around 2,100 square miles, usually attends between 30 and 40 incidents a year.
However this year volunteers attended 57 – with call-outs ranging from a teenager who had fallen from a rope swing to treating injured spectators at the Tour de France and searching for lost hikers.
Incident controller Ian Hugill, from Scarborough, said: “The most memorable incidents last year were where we searched for a missing person and didn’t find them. The families who are still missing their loved ones are important to us.”
Members, who remain on standby 24 hours a day, 365 days a year, were deployed for around 177 hours on search and rescues, which amounts to 2,653 hours of voluntary attendance.
While the team was called out most hours of the day and night and all days of the week, they attended a high number of incidents in or around Dalby Forest on Sundays in August.
Mr Hugill said: “I think there are various reasons why. There are more and more activities going on, including organised mountain biking events and more people using the trails in Dalby. As a result we are seeing more people venturing away from the normal roads and suffering injuries.”
Eighteen per cent of the call-outs were between the hours of 9pm and 7.30am and rescue vehicles travelled an average distance of 16 miles to incidents from the team’s base in Snainton.
However team members racked up considerably more mileage in their own transport getting to and from shouts.
Mr Hugill said: “We would like to thank our supporters and friends for their commitment, team members for their dedication and most importantly family members for putting up with us disappearing at all hours of the day and night.
“So far in 2015 we have already had three incidents so it looks like we will be just as busy this year!”
