Urka

The Urka rises on the southern slopes of the Kulin heights and runs south toward the upper Amur. Its course crosses forested ridges and marshy ground, dividing into branches before joining again. Birch and pine grow in the wet valley, while the surrounding heights separate its waters from other northern streams. The Urka is one of the smaller rivers that feed the Amur from the north, bringing the waters of the inland forests to the great eastward-flowing river.
