Interesting pair of maps showing the route of the controversial Dakota Access Pipeline
The upper map is the official map from Energy Transfer Partners. It is remarkably free of detail. Enter Carl Sack's map below, which contains a lot more detail and was designed explicitly to help oppose the pipeline. It's objectively a better map in many ways, particularly showing the locations of rivers and the Sioux Reservation.
It's also notable that Sack includes the "Unceded Sioux Territory". My understanding (and I could be wrong) is that land has disputed legal status today, the result of a broken treaty with the Sioux. The passing of this pipeline through that land is a key part of the dispute, though, and mapping it helps us understand the protest against the pipeline's passage through that land.
