For completeness, we describe another type of ravine-Yar (Яр).Dann Falk wrote: So there are three different types of ravines, Ovrag, Balka, Dol or Log. Interesting.
We have two varieties of Yar (Яр).
First variant Yar - a Ovrag with a wide bottom. The locals call this Yar.
However, in my opinion this is any more not a Ovrag, but not yet Yar.
Second variant Yar - is tall and steep (almost vertical) the bank of river. This Yar on the Medveditsa river (left tributary of Don), here in November 1942 before the Uranium operation, was hidden the tank corps of 5th Tank Army.
We can say with good reason that the bank of Chir river, where was the position of battle group Selle and on the other hand 1120 Rifle Regiment 333-th RD is Yar (see my photos earlier).
