Manion (Cedar) Creek plunges steeply northward from its headwaters on Hamilton Hill for 4.2 kilometres, entering the Tulameen River 2 kilometres west of the town of Tulameen.
At the Cedar Creek Placer occurrence, gold and platinum-bearing gravels were mined along this creek intermittently between 1886 and 1933. Some coarse gold and platinum, in nuggets weighing 3 to 6 grams, were recovered, in addition to finer dust, by ground sluicing in 1933 (Minister of Mines Annual Report 1933, page 174). Estimated production for 1886 is 1800 grams.
