The Sawlog Creek is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): Age = Quaternary.
Comment (Reference): Primary Reference = Brosgi and Reiser, 1964
Comment (Workings): Workings / Exploration = Williams (1952) reported that the results of a magnetometer survey on Sawlog Creek looking for a pay streak were generally inconclusive, but because the survey was performed at the request of the property owners it suggests some activity at that time. Heiner and Wolff (1968) reported one claim located in 1960.
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Geology): Geologic Description = Brosgi and Reiser (1964) reported recent placer mining in 1964, but there is no other information regarding this placer occurrence. The area is mapped as quartz-mica schist with intercalated greenschist and greenstone. Sawlog Creek heads against Dennys Gulch (CH019), in which there is documented placer activity, and both creeks are just south of the southern end of the Baby Creek batholith (DeYoung, 1978).
Comment (Exploration): Status = Not determined
