Which two Meridians are primarily recognized in Louisiana?

The two primarily recognized Meridians in Louisiana are indeed the Louisiana Meridian and the St. Helena Meridian. The Louisiana Meridian serves as a baseline for surveying and land description in the central part of the state, providing a reference for lot and parcel identification. The St. Helena Meridian, on the other hand, is used primarily in the eastern portion of Louisiana and includes parts of several parishes.

These two meridians are significant because they form the basis for the Public Land Survey System (PLSS) in Louisiana, which is essential for determining property boundaries and ownership. Each Meridian has its own base line for the east-west measurement, ensuring the effective mapping and organization of land throughout the state.

The other options do not include the correct pair. The Mississippi Meridian, although recognized in other contexts, is not primarily used in Louisiana’s land surveying practices. Similarly, while the Sabine Meridian relates to surveying in the bordering areas of Texas, it does not play a central role in Louisiana's meridian system. Overall, knowing the correct Meridians is crucial for understanding land transactions, title insurance practices, and real estate arrangements in Louisiana.
