The lake (Tso Ngonpo, 'Blue Lake', in Mongol dress Kokonor) lies at about 37.0 N, 100.13 E (Wikipedia).
Its east shore, the summer pasture of the Tsongkha horse herds, is the nearest part of the lake to Xining. Wikipedia names an island temple, Mahadeva, 'Heart of the Lake', which historically held a monastery and was a place of pilgrim circuits, especially in Horse years; it gives no date for either. We know of no town or fort on the shore in 1200: it is a camping ground and a fair, in the general pattern of Tibetan lake country.
