Three 1899 survey/plat maps of the Suffolk Mine near La Porte/Grass Flat, Sierra County, California [Wahoo Mining District]

Item: Three 1899 survey/plat maps of the Suffolk Mine in Sierra County, California [Wahoo Mining District, Marysville Land District]

Description: Three survey/plat maps of the Suffolk Mine, located in the Wahoo Mining District in Sierra County, California (Marysville Land District). The maps are based on the surveying made in December 1898 and January 1899 by Arthur Walter Keddie (Mineral Survey No. 3620). Each map is signed by the Surveyor General of California, J. M. [James Malcolm] Gleaves, and is 15.5 x 22 inches. Some minor soiling appears on each of the maps; one shows more significant soiling; there is a bit of light edge-wear. These have been in rolled storage.

The Suffolk Mine is located near the city of La Porte and very close to what is now the ghost town of Grass Flat in Sierra County. The coordinates are T21N R9E (Sections 13 and 24) and T21N R10E (Sections 18 and 19). It mine was originally a claim of James G. Berryhill and was active, off-and-on, up until at least 1936 (the last mention of it that we could find).

The three maps are very close to being identical copies (the two that are actually identical contains a few extra field notes on the map).

The notes in the column indicate the improvements made on the Mining Claim, including a tunnel, air shaft, timber shed, blacksmith shop, dump house, and a boarding house (with values indicated for each). These structures are located on the maps.

The surveys were conducted by Arthur Walter Keddie, who is known as the father of the Western Pacific Railroad. He was a resident of Plumas County and was responsible for developing the railroad line through the Feather River Canyon.
