Princess Catherine and Prince William have shared a new family photo in honour of Mountain Rescue Awareness Day.
The couple took to Instagram on Sunday with a sweet new snapshot showing the Princess's completion of the Three Peaks Challenge in June.
It shows the royal couple along with their three children, Prince George, Princess Charlotte, and Prince Louis.
The future King and Queen wrote in the caption: "On Mountain Rescue Awareness Day, we send our heartfelt thanks to all those who volunteer their time and expertise to keep people safe in some of our most beautiful but challenging landscapes.

"Through our connection with this remarkable organisation, we have seen first-hand the dedication, professionalism and compassion that define their work.
"Meeting local mountain rescue teams during the Three Peaks Challenge this summer was an opportunity to say thank you in person for the vital role they play in keeping walkers and climbers safe on the mountains all year round.
"We are incredibly proud to support the extraordinary volunteers who respond in all conditions, often at a moment’s notice, to help others when they need it most. To everyone across the mountain rescue community, thank you for your unwavering commitment, courage and service." They signed their message, "W & C".
Mountain Rescue Day is deliberately held on the day the clocks go back, and it gets darker earlier, to remind people to be properly prepared for winter conditions, including carrying essential safety equipment such as a torch, before heading to the mountains.
William is the Royal Patron of Mountain Rescue England, and his wife notably completed the Three Peaks Challenge earlier this year in aid of the hospital where she was treated for cancer, describing it as a "chance to explore life beyond diagnosis and to give something back".
She did the event, which involves climbing the highest peaks in England, Scotland and Wales over a day, to raise funds for the Royal Marsden Cancer Charity.
Writing on social media, alongside a picture of herself at the summit of Ben Nevis, she said: "Cancer doesn't just affect the body. It changes how you think and feel and profoundly affects every aspect of life.

"I know this personally, and that the journey through and beyond treatment requires more than medicine alone."
She continued: "Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare.
"Every individual is different, and ensuring there is a whole person approach to care enables those living through cancer to manage the deeply personal challenge of diagnosis.

"Holistic therapies complement clinical pathways and support patients' ability to maintain their wellbeing, resilience and quality of life during an exceptionally difficult time."

On Friday, George returned to the family's "forever home" Forest Lodge in Great Windsor Park for the start of Eton's "long leave" – an extended break that is the £65,673-a-year school's equivalent of half term.
The school holiday is longer than most half terms at 16 days, and will see pupils returning on 8 November, according to Eton's website.
