The site has undergone some clean up and piles of debris and mining equipment have been placed in various piles, Most of the iron has been removed. Still some cleanup should be done, as this is a wet land area and lead was milled at this site. It has an evaporation pond on site, and water content is unknown. Cattle are grazing on the land near-by. Swallows and various other meadow-land water fowl have made the remaining concrete structures their homes. all tunnels are flooded and no access to mine is possible without it's removal. Also an open pit area is flooded no signs of life in it, other than geen algae.

0.0117 - 2.588 Ma

ID: 2987252
Glacial drift, undivided

Age: Pleistocene (0.0117 - 2.588 Ma)

Stratigraphic Name: Nespelem Silt; Salmon Springs Drift: Wingate Hills Drift; Hayden Creek Drift; Vashon Drift; Sumas Drift

Description: Glacial and glaciofluvial sand, gravel, and till; includes alpine glacier outwash and till as well as some Recent alluvium.

Comments: Nespelem silt (in part); Salmon Springs Stade: Wingate Hills Drift, Hayden Creek Drift; Vashon Drift (in part); Sumas Drift; Primarily located in northeast Washington with some deposits along the Skagit River and near Eatonville. The Hayden Creek and Wingate Hill Drifts are alpine glacial deposits. The drift in northeast Washington was deposited by the Cordilleran Ice Sheet in Late and pre-Late Wisconsin (Stoffel and others, 1991). Most deposits are gravel to fine-grained sand. Finer-grained material (silt and clay) is incidental.
