Is there a layer that shows the Public Land Survey System (PLSS)?

PLSS is available by using the Add Data tool in The National Map viewer. PLSS data layers, such as sections, townships, and ranges, are provided by the Bureau of Land Management (BLM) through their REST service endpoint or WMS. BLM provides updated downloadable PLSS data called the Cadastral National Spatial Data Infrastructure (CadNSDI) that complies with latest Federal Geographic Data Committee guidelines. Data is distributed as statewide file geodatabases. Go to this link to open a .pdf with a table showing PLSS CadNSDI data set availability.
