A glacial lake nestled between limestone walls, with a little-known detail: beneath the surrounding meadow, remnants of the old road used to transport materials for the region's former water network are still visible—a nearly erased trace that lends the place a dual character, both natural and industrious. The lake changes dramatically with the light: on cloudy days it appears opaque and heavy, but in sunlight it displays an intense green that reveals its depth and rocky bottom. It's a good spot to pause and appreciate the contrast between the wild landscape and the barely visible but still present vestiges of human activity.
