Table 1: USGS 7.5 Minute Topographic Quadrangles

Table 1 at right shows the USGS 7.5 minute quadrangles (1:24,000 scale topographic maps) which surround the area containing the physiographic features Rio Grande Pyramid and La Ventana. Both of these features are readily visible in the larger version of the photograph on the first page of the tale of La Ventana, which is reproduced again below.

The 7.5 minute quads named in Table 1 can be found in the 37107 block of the United States Geological Survey "COLORADO - Index to Topographic and Other Map Coverage" (publication number 39104-F8-MI-99x) available from the United States Geological Survey, Reston, VA; and are now downloadable at no charge from the USGS here. But note that these topo maps are high-resolution, and so are about 12MB, so can take some time to download depending on your internet connection speed.

The interactive maps below, derived from the central quad of Table 1 (Rio Grande Pyramid), show the physiographic features La Ventana ("The Window") and the Rio Grande Pyramid summit. These two landmarks are clearly visible if you click our photograph at left, and are reported to be visible from the portal of the mine.

The maps below are initially centered on the Rio Grande Pyramid physiographic feature. This is an interactive map display, so you can change the map type and scale, as well as pan and zoom the map to suit you needs. (Zooming out can take several seconds as additional tiles are loaded.)
