Hint

In mountainous areas it might be helpful to turn off the terrain layer in Google Earth.  Otherwise, the survey grid can look distorted as it shapes itself to the earth's surface.

Information: BLM Township and Range

The Bureau of Land Management (BLM) cadastral survey program is responsible for the official boundary surveys for all federal agencies in the U.S. that together manage over 700 million acres. The Public Land Survey System also called the Rectangular Survey System is the foundation for many survey-based land information systems.
