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 (Workings): Workings / Exploration = See individual creeks for specific workings and exploration information: Mammoth Creek, ARDF no. CI036, Miller Creek, ARDF no. CI039, Eagle Creek, ARDF no. CI017 and Mastodon Creek, ARDF no. CI037.
Comment (Production): Production Notes = See individual creeks for specific production notes: Mammoth Creek, ARDF no. CI036, Miller Creek, ARDF no. CI039, Eagle Creek, ARDF no. CI017 and Mastodon Creek, ARDF no. CI037.
Comment (Reference): Primary Reference = Yeend, 1991.
Comment (Geology): Geologic Description = Bedrock in the Mastodon Dome area is varied. Eagle Creek drainage to the west of Mastodon Dome is underlain by both the Upper Quartzite and Upper Schist units described by Wiltse and others (1995). Mastodon Creek is underlain by the Middle Schist and Quartzite unit.? Streams in this area have 5 to 10 feet of gravel under a few feet of muck. Gold is in the bottom few feet of gravel and in cracks in bedrock. Fineness of gold varied from 0.787-0.838 Au and 0.153-0.201 Ag.

Comment (Deposit): Model Name = Placer gold deposit (Cox and Singer, 1986; model 39a)
