Published with survey data from 1937 and reprinted in 1963, it preserves a carefully measured view of the Gulf Coast landscape before many later episodes of industrial expansion, highway development, and coastal change. The map centers on one of Louisiana’s most distinctive geological curiosities: Avery Island, the famous salt dome rising subtly from surrounding marshes, bayous, agricultural tracts, and low coastal wetlands. Its restrained but information-rich style captures both the practical precision of federal mapping and the atmospheric complexity of a watery, shifting landscape.\u003c\/p\u003e\n\u003cp\u003eThe United States Geological Survey was, by the twentieth century, the preeminent American authority in scientific cartography, producing maps that served engineers, geologists, planners, soldiers, and travelers alike. In “Derouen,” the USGS method is evident in the disciplined contouring, clear symbols, and meticulous classification of roads, railways, waterways, forests, and cultivated land. The color scheme is purposeful rather than decorative: blues gather the bayous, lakes, and marsh channels; greens mark wooded or vegetated areas; and contour lines reveal the modest but meaningful relief of a coastal plain where even slight elevation can define settlement, drainage, and industry.\u003c\/p\u003e\n\u003cp\u003eAvery Island dominates the map’s historical and geographic interest. Though called an island, it is in fact a salt dome—a subterranean geological formation that lifts the land above the surrounding marshes. This unusual feature made the place valuable for salt extraction and, famously, for the production of Tabasco sauce by the McIlhenny family. The map’s contour lines quietly convey the island’s raised form, distinguishing it from the watery lowlands nearby. Around it, the intricate network of bayous, drainage channels, and wetlands reflects the ecology of Iberia Parish and the broader Louisiana coastal zone, where land and water interlace in endlessly variable patterns.\u003c\/p\u003e\n\u003cp\u003eThe surrounding names extend the story beyond Avery Island: Weeks Island, Vermilion Bay, Lake Fausse Pointe, and Lake Peigneur all situate the map within a region shaped by salt, oil, fisheries, agriculture, and waterborne movement. Roads and railways thread cautiously through the terrain, connecting small settlements, industrial sites, and agricultural lands while negotiating marshes and bayou crossings. The depiction of cultivated fields beside forested tracts and salt marshes evokes a landscape in transition between rural production and extractive enterprise. These details make the map not merely a geographic record, but a portrait of coastal Louisiana’s working environment in the late 1930s.\u003c\/p\u003e\n\u003cp\u003eSeen today, “Derouen” carries particular historical resonance because Louisiana’s coast has changed so dramatically. Wetland loss, subsidence, canal cutting, storms, and industrial development have altered many Gulf Coast landscapes since the surveys on which this map was based. The map therefore offers a valuable snapshot of waterways, shorelines, roads, and land use before several decades of ecological transformation. Its careful rendering of marshes, bayous, and low relief also underscores the fragility of this region: a place where geology, water, commerce, and culture meet. For collectors, it is a refined and revealing document of one of America’s most distinctive coastal environments.\u003c\/p\u003e\n\u003ch2\u003eCities, towns and places on this map\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAvery Island\u003c\/li\u003e\n\u003cli\u003eWeeks Island\u003c\/li\u003e\n\u003cli\u003eVermilion Bay\u003c\/li\u003e\n\u003cli\u003eLake Fausse Pointe\u003c\/li\u003e\n\u003cli\u003eLake Peigneur\u003c\/li\u003e\n\u003cli\u003eBayous\u003c\/li\u003e\n\u003cli\u003eVarious roads and railways\u003c\/li\u003e\n\u003cli\u003eSalt marshes\u003c\/li\u003e\n\u003cli\u003eForested areas\u003c\/li\u003e\n\u003cli\u003eAgricultural lands\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHistorical context \u0026amp; cartographic details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduced by the United States Geological Survey, this 1:62,500 topographical map uses survey data from 1937 and was reprinted in 1963.\u003c\/li\u003e\n\u003cli\u003eThe map reflects the geography of the area in the late 1930s, offering insight into later ecological and infrastructural changes, including coastal erosion and industrial development.\u003c\/li\u003e\n\u003cli\u003eIt uses color to distinguish land uses and natural features, including blues for water bodies and greens for forested and agricultural areas.\u003c\/li\u003e\n\u003cli\u003eThe map depicts elevation contours and wetland terrain, highlighting the coastal character of the region.\u003c\/li\u003e\n\u003cli\u003eAvery Island is notable for its salt dome and its association with the Tabasco sauce factory.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eLooking for a particular place?\u003c\/strong\u003e Review the detailed images to confirm that the town, landmark or feature you have in mind appears on the map.
