With careful examination for grid markers, the federal-land-state townships and ranges usually can be identified in a Rand McNally ''Commercial Atlas and Marketing Guide''<ref>Rand McNally and Company, ''Commercial Atlas and Marketing Guide'' (Chicago : Rand McNally, 1989). {{WorldCat|22500935|item|disp=At various repositories (WorldCat)}}.</ref> found at most large libraries. Each township has a range strip and a township strip. Together they create an address for that township within the boundaries of their ''principle meridian&nbsp;'' and ''baseline''. Begin counting where the principal meridian and baseline intersect. If the township address is T2N R3E, it means that the township is two units north of the baseline, and three units east of the principal meridian. Similarlly, a township address of T3S&nbsp;R1W would be three units south of the baseline, and one unit west of the principal meridian.

[http://www.earthpoint.us/Townships.aspx Earthpoint: Tools for Google Earth] displays a Google Earth map based on BLM township, range, section, and quarter-quarter section if you zoom in close enough (most, but not all areas have quarter-quarter sections mapped). The tool can convert township, range, and section to latitude and longitude, or vise versa.
