Buh Depression [Надбужанська котловина; Nadbuzhans'ka kotlovyna]. The western part of Little Polisia, the Buh Depression forms a triangle bounded by the Roztochia hills in the southwest, the edge of Podilia in the southeast, and the recess of the Volhynia-Kholm Upland in the north. The depression is of tectonic-erosive origin. The northern part is a moraine-sand or sand outwash plain, in many places covered with pine forest. The southwestern part consists of low, flat, latitudinal chalk hills, covered mostly with loess, which are dissected by broad, swampy hollows.
