Summary
Fault plane in quartz passing from footwall to hanging wall, Sixteen to One Mine, 800- foot level. Vein is in the unusual condition that neither wall is formed by a fault and stringers extend out into both foot and hanging walls. The straight boundary along a small part of the footwall (to the right of the center) may be due to a fault prior to the introduction of the quartz as it does not cut the quartz. Sierra County, California. 1924. Plate 16-B, in U.S.Geological Survey Professional paper 172. 1932.
