At the confluence of the Avižlys and Venta rivers, the erosion of both rivers has created a unique form of nature - a narrow and long spur. Approaching the Venta, Avižlys falls into an ever deepening valley. And behold, hundreds of meters before the confluence, the valleys of the Venta and Avižlys become interspersed, they are seperated by a steep embankment of steep, tree-covered shrubbery slopes that ends at the confluence with a steep outcrop. It is a ridge about 112 meters long with steep slopes, ending in a steep outcrop at the very confluence of the two rivers. It shows layers of pleurisy and sand, which probably settled in a lake that was here 50 to 70 thousand years ago. Preliminary research of the outcrop have shown that this form may be a glacial tectonic fold (glaciotectonic deformation) flushed on both sides by the waters of the Venta and Avižlys rivers.
