The Pagramančia Outcrop is a cliff on the left bank of the Akmena River, situated in a stunning loop of the river, in the northern part of the Pagramančia town. The height of the outcrop is 29–31 meters, and its length along the river is 203 meters. The value of the Akmena Valley outcrops lies in their representation of the middle and upper Pleistocene epochs, akin to an opened book of the Ice Age. Its pages consist of layers of moraine clay, sand, silt, and clay, left by the glaciers that once covered Lithuania. The outcrop represents nearly 200 thousand years of geological history of the Pagramančia surroundings and the southern Žemaitija highlands.
