Newton Creek flows east to northeast, over a distance of about 11 kilometres, into Granite Creek, west of Princeton.
The lower half of the creek cuts through a narrow steep-sided valley while the upper half flows over a broader, more open valley floor.
Gold and platinum were produced from gravels in this creek between 1890 and 1893. The gold to platinum ratios are reported to be 1:1 (Geological Survey of Canada Memoir 171, page 113). The gold is similar to that found in Granite Creek (092HSE230), being coarse and rough. Some of the larger nuggets contained quartz (Minister of Mines Annual Reports 1890, 1933). Total gold production is estimated at 6500 grams.
