Summary

High-resolution, terrestrial laser scanning (TLS), was used to quantify the volume of sediment eroded from outcrops at Malakoff Diggins State Historic Park, located about 17 kilometers (km) northeast of Grass Valley, California. TLS was used to create centimeter-scale, three-dimensional (3-D) maps of the complex outcrop surfaces, which could not be mapped non-destructively or in sufficient detail with traditional surveying techniques. To develop a comprehensive sediment budget for the Malakoff Diggins mine pit that will help identify sources of sediment and metals within the pit that comprise the suspended sediment discharged from the pit into Humbug Creek, the USGS used TLS technology to quantify the eroded volumes and erosion rates [...]

Purpose

The purpose of this data release is to make publicly available the point-cloud data that was used to calculate the volumes of eroded sediment and the rates of erosion, for nineteen sedimentary units at four study sites in the Malakoff Diggins mine pit from December 2014 to August 2017. The results of this study will be combined with laboratory determination of grain-size distribution, mineralogy, and geochemistry of the various sedimentary units to identify sources of sediment and metals within the pit that comprise the suspended sediment discharged from the pit through the Hiller Tunnel. Results from this investigation can be used by California State Department of Parks and Recreation and California State Department of Water resources to facilitate the design of an effective sediment and heavy-metal abatement program for water discharged into Humbug Creek and to determine whether stabilization of sediment source areas may be needed at the Malakoff Diggins pit.
