Below are all figures used in this paper (click images for a larger version), along with a few extras at the bottom.
Figure 1. Sherrod and Rolingson's (1987:37, Figure 9) map of the Toltec Mounds site, showing the location of mounds, the embankment, and Toltec Module distances radiating from the center of Mound A. Tick marks on lines are 95 m (2 x the Toltec Module). |
Figure 2. Diagram of the propagation of error as employed by Sherrod and Rolingson. Because the 10% margin of error is applied to the entire distance being measured, it becomes larger with each TM increment. At a distance of 5 TM, the margin of error equals 1 TM, and it becomes impossible to find any measurement which is not within 10% of the 'error'. |
Figure 3. Mound B at the Toltec Mounds site, facing northeast. The break in slope angle represents the upper limits of slope wash; the mound has likely been altered both above and below this point.
|
Figure 4. GIS model of the Toltec Mounds site showing mound and mound center point locations. |
Figure 5. TM increments (+/- 2 m) as measured from the edge of Mound A. Of the area within the embankment (shaded area), 8% is covered by a TM multiple. |
Figure 6. Overlap of all TM increments (within the embankment only) from the edges and centers of all mounds and the edge of the embankment. Overlaps have been reduced to three categories for display. |
Figure 7. (Left, a): Distance surface: all points are coded with their distance from the edge of Mound A. (Right, b): Distances corresponding to all other mounds and the embankment have been extracted by masking out all other cells. |
Figure 8. Histogram of distances from the edge of Mound A to all grid cells within all other mounds and the embankment. The most common distance measurements are between about 150 and 200 m. Vertical bars represent TM multiples. |
Figure 9. Histograms of all distances from the edges and centers of all mounds and the edge of the embankment, measured to all grid cells within the mounds and embankment. Vertical bars represent TM multiples. |
Figure 10. Periodogram of the spatial-series data presented in Figure 8. Frequencies of 2 and 4 m are weakly expressed. These frequencies are an artifact of the square raster cells; distance measurements are "stepped" around the edges of mounds (see Figure 11). The most significant frequency within the data occurs at 720 m. |
Figure 11. Bar graphs of the most significant frequencies derived through all four iterations of periodogram analysis. |
