Summary
[edit]DescriptionComparison of the rectified channel of the Rio Grande with a previous natural channel.svg |
English: For the purposes of comparison, I overlaid an OpenStreetMap.org map of the U.S.-Mexico border in the El Paso-Juarez Valley (over the entire distance of the 1935-1938 Rio Grande Rectification from El Paso to Little Box Canyon, south of Fort Quitman). I created an overlay with an Inkscape tracing of the border as it existed well prior to the rectification. I obtained the tracing of the old border from 1908, 1907 and 1894 USGS maps that are available at the "USGS Store" website. In this SVG file, the current border from OpenStreetMap (aquamarine color) is overlaid on its northern half with the border from the 1908 and 1907 maps (black color) and on its southern half with the border being the river as shown in the 1894 map (black color). Note that in the 1908 map of the El Paso Quadrangle, there are several places where the border does not coincide with the then-current course of the Rio Grande, including a significant cut-off area that is too large for the Banco Convention of 1905 to apply.
