The great fresh lake into which the Khalkha flows, with fisheries and good winter pasture round its shores.
In 1200 the Tatars hold the west and north shores; the Onggirat lie east. A route to the Jin boundary trench and its licensed markets runs south from it. The regional brief names Buir Nur's fish and the salt of Hulun Buir; we have no source for 1200, so the trade is an inference from the region's later record. English Wikipedia (Rise of Genghis Khan) has Jin defensive fortifications near Buir Lake by the Koyiten fight of 1201 or 1202; whether they stand on 1 January 1200 is not pinned.
