The Mississippi River as well as the Tennessee and Cumberland Rivers formed and cut deep into the valleys. The Nashville Basin , which in reality is a geologic dome , was pushed up from underneath by a mantle plume , exposing softer strata that with additional erosion on the Highland Rim surrounding the basin expanded the size of the basin.

In 2015, the USGS unveiled the topoView website, a new way to view their entire digitized collection of over 178,000 maps from 1884 to 2006. The site is an interactive map of the United States that allows users to search or move around the map to find the USGS collection of maps for a specific area.
