The sunken lane (wąwóz drogowy, holweg), at the north-western edge of Samborowiczki village, made in Pleistocene loess deposits. It runs in a depth of up to 5 meters, with characteristic, very steep walls with an inclination reaching 80°. Loess deposits of the area lie on much older paleozoic and proterozoic rocks, building the majority of the Strzelińskie Hills.
