Using USGS Digital Elevation Model data, along with latitude and longitude coordinates from the Lists of John peak list website, I have put together completion maps of my Colorado 13ers and 14ers. The grayscale values are directly proportional to elevation, with green dots representing completed peaks and red dots representing uncompleted peaks. The first map shows all the 13ers in the state, while the second map shows just the "heartland" of Colorado, where I have done most of my ascents.
