US Topo maps are not legal documents and the Public Land Survey System (PLSS) representation is not legally authoritative.
The sections, townships, and ranges of the PLSS that are shown on US Topo maps are derived from GIS data from the Bureau of Land Management (BLM) in cooperation with the Federal Geographic Data Committee (FGDC).

The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. Some of the most well-known USGS maps are the 1:24,000-scale topographic maps, also called 7.5-minute quadrangles . In 2009, the USGS transitioned from our hand scribed historical topographic maps to US Topos , which are computer-generated on a regular schedule using national databases...
Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series was launched in 2009 and branded " US Topo ." Though...
The Public Land Survey System (PLSS) is a way of subdividing and describing land in the United States. PLSS surveys, which are available for portions of land in 30 southern and western states , are made by the Bureau of Land Management (BLM). The PLSS typically divides land into 6-mile-square townships. Townships are subdivided into 36 one-mile-square sections. Sections can be further subdivided...
GeoPDF files for both Historical Topographic maps (produced 1884-2006), US Topo maps (produced 2009-present), and OnDemand Topo maps come with an XML metadata file attached to each GeoPDF file. To access the metadata file, download the GeoPDF file, open it in Acrobat Reader, click on the paperclip icon, then select a file from the list that appears (US Topo maps also come with a Map Symbols...
Superseded US Topo maps will remain available for download, but will not become part of the Historical Topographic Map Collection , which is scans of USGS topographic quadrangles originally published as paper documents between 1884-2006. The first US Topo maps were published in 2009. They are updated and superseded every 3 years (maps for one third of the country are produced every year). This...
US Topo maps have a credit legend in the lower left-hand corner of the map collar. This includes a short summary of data sources and data currency. More detailed source information is in an XML metadata file attached to each GeoPDF file. This file contains series-level, quad-level, and layer-level metadata, but US Topo does not preserve or track feature-level metadata. Open the GeoPDF map file in...

A USGS elevation benchmark in Bryce Canyon National Park.
Bryce Canyon is a unique sandstone formation in southern Utah. It is home to a large number of hoodoos, which are oddly shaped pillars of rock that formed due to different erosion rates for the dolomite that caps them and the sandstone that forms their base.
