Figure 1 Aerial photographs of a particularly karstified section of the Columbia Quadrangle, taken over half a century apart, show how agricultural activities have changed the terrain. Figure 1a is derived from a U.S. Geological Survey Digital Orthophoto Quarter Quadrangle (DOQQ) produced from aerial photog­raphy acquired on March 3, 2005, showing the eastern portion of Section 34 and the western portion of Section 35, T1N, R10W. Figure 1b is from a digitized U.S. Department of Agriculture aerial photograph taken on July 5, 1940, and illustrates the same one-square-mile area. Comparison of these two images reveals a number of changes that have occurred on the landscape during the 65-year interval. The 2005 image shows sinkholes that have been remediated using stand pipes and then later filled in to increase cropland area. Subtle, near-surface circular patterns diagnostic of sinkholes are quite apparent in the 1940 image, especially in the agricultural fields located on the western portion of this image. Note how these patterns have largely been erased in the 2005 image because of decades of use with modern, large-scale farming equipment and further obscured by the widespread adoption of conservation tillage meth­ods. Scale 1:12,000.
