Gubakha
Gubakha arose in 1755 beside an iron-ore deposit on Krestovaya Mountain, at the meeting of the Gubashka and Kosva rivers. The village served as a landing for barges that carried ore from the upper Kosva toward the Kama. Coal was found on Krestovaya Mountain in 1825, and the first mining adit was opened there. At first output remained small, with coal floated down the Kosva to the ironworks at Chermoz.
