Popovka
Pavlovsk, Popovka River valley
The Popovka River Valley, located south of Pavlovsk, is a natural monument of regional significance. In its middle course, the river has cut a deep canyon, the sheer slopes of which reach heights of 18–25 meters in places, and the bedrock is exposed for a distance of two to three kilometers. The valley area contains more than 20 outcrops of steeply inclined Paleozoic rocks, which are folded in places and attract geologists. Trilobite fossils, orthocones, endoceratids, echinospharitids, as well as obolus shells are found in the limestones.
