INTRODUCTION

Topographic surveys of abandoned, acid producing mine dumps were performed at four sites in Colorado to provide reference maps for U.S. Geological Survey research projects for geochemical and geophysical characterization of mine dumps. Two of the sites are located in southwestern Colorado near the town of Silverton, and the other two sites are located in central Colorado near the town of Leadville. The sites have been named for the mines located on them. The sites near Silverton are located along Cement Creek just north of town, and have been named the May Day (also known as BLM60) and Yukon ( also known as Gold Hub) sites (Figure 1). Those near Leadville are located east of town on Ball Mountain and are named the Venir Pile and Sunday #2 (Figure 2).

The topographic base maps resulting from these surveys contain information useful to ongoing research. Included in the maps are topographical features such as roads and hills, geophysical profile locations and grids, some geochemical sampling cells, biochemical sampling points, and other pertinent features such as vegetation "dead zones" produced by acid runoff from the dumps. The goal in producing these maps was to tie sample sites to topography, in some cases helping to interpret data. Many of the sites may need to be reoccupied in the future, accordingly steel pins (12" nails) were placed in the ground at all EDM locations to facilitate surveying of additional points or measuring changes of features such as vegetation boundaries with time.

EQUIPMENT

A Sokkisha Set 2 electronic distance meter (EDM) was used for surveying. A a HP-7 IB handheld computer was used for data logging. Digital surveying data were transferred directly from the EDM to the HP-7 IB. A corner reflector, tripod, barometer, thermometer and notebook completed the field equipment. The computer program used to record and download of data from the EDM to the HP- 716 is described in Lucius (1997). Distances are estimated to be accurate to 1-2 cm, and elevation differences accurate to 2-4 cm. While this instrumentation is capable of much more precise surveying, this was not warranted for our purposes. Absolute positioning of the survey points was done using a military GPS receiver (Rockwell Precison Lightweight GPS Receiver or PLGR). Absolute horizontal and vertical positioning are generally estimated to be better than ± 15 and ± 5 meters respectively as indicated by the PLGR.

DATA PROCESSING

After data were transferred from the HP-7 IB to a minicomputer they were converted to ASCII text files and manually editted to remove any erroneous points. The data were collected along geographic features such as the edges of roads, breaks in slope, and grid points to allow plotting of these features to provide points of reference. Data points are given as (x,y,z) coordinates relative to a local reference point (REF) for each site. These data are tabulated in the Appendices. All of the data points for each site were gridded using gdminc (Webring, 1981) to produce elevation grids. Maps were produced from the elevation grid and

topographic feature files using gdclrx, a display program written by Robert Simpson (U.S. Geological Survey, Menlo Park). Figures 3 through 7 show the completed topographic maps.

DISCUSSION

The May Day (BLM 60) site (Figure 3) is characterized by a series of slopes and benches, the main road runs diagonally from the southeast corner of the map to the north end of the map, and is marked by a dashed line. A spur road (dashed) branches off from the main road and follows the first bench northwest towards the top of the mine. A geophysical and geochemical grid is marked on the site, along with the location of a geophysical transect. Well locations and bench edges are also included. Instrument points EDM1, EMD2, and EDM3 were located using GPS (see Table 1).

The Yukon site, also known as Gold Hub, ( see Figure 4) is characterized by a large upper bench, one major slope, and several buildings and other permanent features. The road on the north side of the site is used to gain access to the upper bench. The outline of two buildings are shown on the upper bench: a garage and a collapsed shed. The location of the mill below the upper bench is shown, while its extension to the upper bench is not because of siting problems. Railroad tracks and geophysical transects are included, as well as the grid system laid out for geophysical and geochemical work. The location of spring to the west of and below the mill were not measured with the EDM, but rather sited on the map (W. Wright, written commun., 1998). The GPS coordinates were obtained for points EDM1, EDM2, and EDM3.

The Venir Pile (Figure 5) is characterized by a series of lobes that extend out from a level bench, then drop off a steep slope to a lower bench. Geophysical lines and DC resistivity sounding locations, and geochemical sampling points are shown on the map. The leader identifying the various geophysical lines points to the zero end of the lines. The geophysical lines were named LB1, LB2, LB3, LB5, and MLB for the various lobes and mini-lobe of the pile. EDM locations and reference points are marked. GPS locations were obtained for the west end of geophysical line MLB and the east of geophysical line LB2.

The Sunday #2 site (Figure 6) is characterized by a medium sized mine waste pile, a long gentle down sloping trend to a road, then a steep descent into a ravine below. Numerous pits surround the site as well as smaller waste piles. Roads, the vegetation "dead zone", upper and lower surfaces of the main pile and surrounding features are all included. The grid system laid out for geophysical and geochemical work is marked, along with geochemical sampling cells and the biochemical sample sites. The location of DC resistivity soundings are shown. These locations were measured relative to grid markers using a tape. EDM locations are labeled. GPS coordinates for several points are given in Table 1. Only the locations of EDM1 and BIO2 are marked as GPS locations in Figure 7. Figure 7 is an enlarged view of the main pile and its immediate surroundings showing the geophysical grid and geochemical sampling cellss in more detail.

SUMMARY

Topographic surveys of the four mine dumps in Leadville and Silverton, Colorado, resulted in topographic base maps that will be used for current and future studies by the U.S. Geological Survey. Key points such as sampling sites and fixed features are included on the maps to aid in reoccupation and interpretation of data. GPS coordinates enable the maps to be accurately tied into a global coordinate system,

APPENDIX

This appendix contains tabulations of surveying data for the four dump sites. Included in the data are a location identifier, (x,y,z) position relative to the reference point, and a comment. The distances are given in meters relative to the first surveying instrument site (EDMl). The direction of the x-axis is the line running from EDMl a reference point (REF). The reference point was usually taken as some fixed and easily recognizable feature. In some instances a steel pin placed in the ground and used for the reference.
