This dataset includes data for in-situ solid materials and suspended sediments from surface-water samples, as well as surface-water chemistry from samples collected during storm events at Malakoff Diggins State Historic Park, Nevada County, California. In-situ solid samples were collected during 2015 along six vertical transects along the cliff walls of the mine pit. Surface-water samples were collected during 2014 and 2016 from Hiller Tunnel and from drainage networks below the in-situ sampling sites during runoff conditions. In-situ and suspended-sediment samples were analyzed for grain-size distribution, X-ray diffraction (XRD) for quantitative mineralogy, inductively coupled plasma - mass spectrometry (ICP-MS)...
