If the land being described is unsurveyed or partially surveyed, add the words "unsurveyed" or "partially surveyed" to the legal description. Of course, only administrative actions can be based on descriptions of unsurveyed land. All conveyances must be based on official surveys.

For example:

Sixth PM T & R sec. 1, all, unsurveyed; sec. 2, all, partially surveyed; sec. 3, all.
