The Pacific Coastal Lowland of Sinaloa and Nayarit is a tract of marshy strand plain fringed by mangrove and lagoons along the west coast of Mexico in the southern part of Sinaloa and the northern part of Nayarit. The physiography of the mainland coast of the Gulf of California naturally subdivides into three provinces 1 a coastline of rocky headlands separated by alluvial fans north of Guaymas, 2 a broader central portion of coalescing alluvial plains, deltas, and sand ridges from Guaymas to San Blas, and 3 a steep rocky shoreline that rises abruptly from the sea to elevations over 3,000 feet south of San Blas. The section under study in this paper is the southern half of the central province and includes the coast of southern Sinaloa and northern Nayarit. The climate, vegetation, landforms, and geology of the region are discussed.
