A lode Au occurrence/mine located in sec. 29 & in the SE¼ sec. 30, T14N, R11E, MDM, about 2.2 km SW of Sage Hill and about 8 km (4.8 miles) ENE of Foresthill, along Ladys Canyon, on French Meadow Road, on private land. The Eagle's Nest was a discovery pit at the top and some adits lower down in a five-level deposit of crystallized gold. The De Maria Mine is also on this deposit.
NOTE: Specifics regarding this mine's location are based on the data for the De Maria Mine at the lowest level of the same deposit.
The Mystery Wind Mine does not exist as a separate mine (Dona Leicht, pers. comm.) and was a made-up name used to conceal the origin of the specimens as was Eagle's Nest. (Wayne Leicht, pers. comm.) Both Mystery Wind and Eagle's Nest specimens are from the upper levels of the De Maria property and should be labelled Eagle's Nest as that was the published locality.
