Landowners and courts may not accept surveys that have not been approved by the BLM. |

Witness corner; Meander corner. A witness corner "stands in" when the true corner cannot be monumented or occupied because of difficult terrain or obstruction of the corner sight. The witness corner must be on the section line and is usually 5 or 10 chains away from the true corner. A meander corner is the intersection of a township, range, or section line and the banks of a navigable stream or meandering body of water. |
