chutes. . . ) were noted. Drainage characteristics were also recorded. Post reclamation features such as, low water crossings or water bars were located in the field and marked by placing wood lathe at the appropriate locations. The location of each feature was measured and recorded so that each may be located on a map to be included in a bid document. Considerable time and effort was expended on Roads C, E, F and G. These are the haul roads which lead to Mines 4 (road C) , 3 (roads E, F) and 5 (roads E, G) . The effort to map and characterize these roads for reclamation purposes was divided into three phases. The first phase was to measure each road. While each road was being measured existing culverts were mapped. The diameter and depth of burial (inlet and outlet ends) was noted. Erosional characteristics at the outlets were observed and recorded. Natural drainage characteristics were observed and the proposed location of stream crossings, low water crossings and water bars were mapped. These features were located in the field by driving a piece of wood lathe at each proposed location. Geologic conditions and road construction techniques were noted at each proposed water diversion structure location. The second phase of the project was to collect information regarding the physical attributes of each road. This information will be used in conjunction with the information collected in phases one and three to develop an understanding of the road conditions. Ten cross sections per mile of each road were surveyed using either the total station survey instrument or hand instruments. The cross sections traverse from the road cut hill slope, across the inside drainage ditches, through the road surface and down the road outslope. Measurements of the road slope were also made at each cross section location. Geologic conditions and road construction techniques were noted at each station as well. The third phase of the project was to collect data necessary to create an accurate map on which to plot the information obtained in phases one and two. An agreement was reached with the Office of Surface Mining which allowed the Division to be trained in the use of the Global Positioning System (GPS) by OSM personnel. The agreement also allowed the Division to utilize a GPS data logger and the appropriate software. Each of the four roads were mapped using the GPS data recorder. The location of each culvert and the reclamation drainage features located during phase one were mapped. In addition to the four roads, haul roads A and B, the Rock Tunnel Entry and Dump, and the upper and lower coal storage areas were also mapped. The GPS data will be used to create maps of the four roads on which 12
