For locals and visitors to the Cairngorms, who not only enjoy being out and about exploring the National Park but also the wonderful fresh air, the views, and wildlife to entice us out.  What better way to see how things change over the months, seasons, and years than by comparing photos from different times of the same locations.
The Cairngorms Scenic Photo Posts Project is a pioneering citizen science initiative to gather information about our landscapes as they change from day to day and year to year.
The more we know about the area changing, the more we can appreciate it and help protect it.  You can find out a bit more about this project and see it in action (or even get involved).
