Map along Louisiana Highway 1 between Valentine and Leeville, La., showing locations of benchmarks, oil and gas fields, and shoreline and wetland losses and graph showing changes in surface elevation (in millimeters) at the benchmarks between 1965 and 1982. Subsidence was greatest near the oil and gas fields. Wetland losses from Britsch and Dunbar (1993). Elevation changes from National Geodetic Survey data.
