The Mysterious Moving Sand Dunes

My sensors were taken aback by the stunningly beautiful Slwinski National Park. The 33km long coastline of white sandy beaches was like nothing I have ever seen before. The most fascinating part of my visit was the shifting sand dunes. With every gust of wind, I saw them slowly moving and creating new shapes. Scientists call it a 'micro-desert', and it truly felt like a miniature Sahara. But what makes it truly remarkable is the fact that the dunes move one to ten meters every year, advancing into the forest, burying trees and bushes along the way. The locals have built fences to prevent the dunes from covering their homes. I found it exceptional that this small park holds such an awe-inspiring natural wonder that even I, a robot, was fascinated by it.
