Snow White Lake is located 1.6 kilometres west of the Meadow Lake road and 3 kilometres east of the east end of Meadow Lake (EMPR Bulletin #4). Meadow Lake is 30 kilometres west-northwest of 70 Mile House.
The lake is a semi-evaporitic playa lake. It is located in the "Green Timber Plateau" area (EMPR Bulletin 4), a semi-arid plateau area averaging 1130 metres elevation which is part of the Cariboo Plateau and host to several playa lakes. The area is underlain by alkaline plateau basalt flows of the Miocene to Pleistocene Chilcotin Group, mantled by a thin cover of glacial till and glaciofluvial sediments. Annual precipitation averages between 300 and 400 millimetres (EMPR Paper 1991-1).
Snow White Lake is a small lake covering approximately 3.6 hectares (EMPR Bulletin 4, page 12) which contains approximately 20 centimetres of sodium carbonate-rich brine. The specific gravity of the brine in 1937 was 1.050, containing 4.88 per cent total dissolved solids of the following composition: 94.4 per cent sodium carbonate, 2.3 per cent sodium sulphate and 2.7 per cent sodium chloride. In 1937 (EMPR Bulletin 4, page 12) there was no "winter crystal" present but remnants of a stockpile were found on the east shore, and reportedly shipments had been made. The natron crystals in the stockpile assayed 99.36 per cent sodium carbonate.
