This page covers the process of making a topo map.
Inspired by this D3 sketch: http://bl.ocks.org/herrstucki/6312708
Github readme for that sketch here: https://github.com/interactivethings/swiss-maps/blob/master/README.md
Ultimate goal: map topo data from the National Map Viewer (maybe even automated somehow!)

Downloading Data
Selecting a location for which I wanted topological data, I faced the dilemma of not knowing which data set to select.
I narrowed the view down to a specific region. I then clicked the download data link at the top.
I was presented with an array of choices, and I chose "Contour" data. This gave me multiple shape files, two of which covered the region of interest. I went through the checkout process to download these two shapefiles.
The region that I'm looking at is the Barry Goldwater Bombing Range outside of Yuma, Arizona, on the southwest Arizona-Mexico border.
Loading into QGIS
Here is what the shapefile looks like when loaded in QGIS... woah!
