puolijalokivien
Puolijalokivien are a type of geological formation characterized by their semi-circular or crescent-shaped appearance. They are typically found in areas with significant glacial activity, such as the Scandinavian Peninsula and the Canadian Shield. These formations are created when a glacier erodes the landscape, carving out a U-shaped valley. As the glacier retreats, the valley walls may collapse, forming a semi-circular or crescent-shaped depression. The term "puolijalokivien" is derived from the Finnish language, where "puoli" means half and "jalokivi" means precious stone, reflecting the semi-circular shape of these formations. Puolijalokivien are of interest to geologists and landscape enthusiasts due to their unique shape and the geological processes that create them. They are also popular among hikers and outdoor enthusiasts for their scenic beauty and the challenges they present for navigation.
