p <br />f areas with good site potential. The upland hillslope is divided into five components; in <br />descending order, these components are the summit, shoulder, backslope, footslope, and <br />toeslope (Figure 9). <br />Summits, the upper portion of the landform, tend to be fairly stable, but are subjected to <br />minor eolian deposition and some erosion. Shoulders are formed by the gradual cutting <br />back of the hillslope and are generally convex with a low degree of slope. Backslopes are <br />erosional features formed by the cutting back of the valley wall. Footslopes are the lower <br />remnant of the hillslope. This eroded surface is often covered by colluvial materials from <br />the shoulder and backslope. Toeslopes consist almost completely of colluvial material at <br />the base of the upland. Because of their low degree of erosion and relative flatness, <br />summits and shoulders have a high site potential. These landforms are capable of <br />containing intact, shallowly buried archeological materials. Likewise, footslopes and <br />toeslopes are considered to have good site potential because they are depositional in <br />nature and generally have a low degree of slope. Backslopes, because of the steep slope <br />and high degree of erosion, rarely contain intact, primary context archeological materials. <br />Investigation Techniques <br />The fieldwork was conducted on November 19-23, 1996 by BCA staff. Initially, the <br />project area was walked in order to look for mounds, depressions, foundations, and other <br />surface visible sites. During this initial walkover, the historic sites were located, and <br />areas that required shovel testing were identified. Because of the snow cover, shovel <br />testing was deemed necessary across the project area (Plates 1 and 2). Low, wet areas, <br />heavily disturbed land, and slopes greater than 15 percent (State Historic Preserv’ation <br />Office (SHPO) 1993) were not shovel tested (Figures 3a and 3b). Shovel tests were <br />excavated at fifteen meter inter\'als acro*^s the relatively level uplands. The number of <br />shovel test transects was dependent on the width of the landform. Table 2 details the <br />eleven shovel test areas that are plotted on Figures 3a and 3b. <br />Two sites, three properties, and a farmstead with four structures older than 50 years were <br />located and recorded during the fieldwork. As a part of recording the sites and properties, <br />shovel tests were excavated at five meter interv'als across each site’s area. Following the <br />fieldwork, site and structure forms were submitted to the Minnesota State Historic <br />Preservation Office and the Office of the State Archeologist (OSA) (Appendix A).
