Ust-orda Buryat

Also called �Ust-ordynsky Buryat,� autonomous okrug (district) in Irkutsk oblast (province), east-central Russia. It lies west of Lake Baikal and extends across the Angara River. The okrug was created in 1937. Its plateau relief is partly in boreal forest, or taiga, of larch, spruce, fir, pine, and birch and partly in forest-steppe. Coal is mined in the west, where the Trans-Siberian Railroad crosses the okrug. Timber
