South Dakota topographic maps

These topographic index maps for South Dakota state are provided by the U.S. Geological Survey (USGS) for map sheet identification. To locate the USGS topo quad in South Dakota that you are trying to find, look at the index map of the appropriate map scale.

1:24,000 scale South Dakota topo quads

The index map below is for South Dakota topo quads at 1:24,000 scale. It is zoomable, and you can find the name of the 1:24,000 scale map (sometimes abbreviated as "24k") written diagonally across rectangular boxes that define the borders of the individual 24k map sheets.

Note that a rare few of the 1:24,000 scale (aka 7.5 minute) maps in South Dakota state might actually be at 1:25,000 scale, which is a very minor difference in map scale. Some of these 1:25,000 scale maps also cover a larger area than regular 7.5 minute maps. Those maps are 7.5´x15´ topo quads, and can be identified on the index map below by a larger sized rectangle that is twice as wide as usual (covers twice the longitude). The map names for these sheets are labelled horizontally, not diagonally.
