Development of the geomorphological map for William Floyd Estate – a unit of the Fire Island National Seashore: Principal characteristics and components
Psuty NP, Schmelz W, Spahn A. 2018. Development of the geomorphological map for William Floyd Estate – a unit of the Fire Island National Seashore: Principal characteristics and components. Natural Resource Report. NPS/NRSS/GRD/NRR—2018/1593. National Park Service. Fort Collins, Colorado
This report incorporates the geomorphological map, its philosophical underpinnings, legend descriptions, and the GIS data layers for the William Floyd Estate (WFE), Mastic Beach, New York. The theme of the map follows the current scientific organization of geomorphological mapping that includes morphometrics, causative processes, and evolutionary stages. Surface form was interpreted from data sets including recent orthophotos, recent Light Detection and Ranging (LiDAR) data sets, augmented with spatial information on soils and vegetation, and field visits. The geomorphological features of the site include: 1) glacial outwash topography created during the late phases of Wisconsinan continental ice advance; 2) coastal landforms and wetlands that developed recently when sea level was at or near its present position; 3) fluvial topography associated with the small streams that dissected and alluviated small valleys in the outwash plain, and 4) anthropogenic modifications to the natural topography, consisting of positive as well as negative changes. The geomorphological map and its legend portray the spatial and temporal association of the surface features created during these stages of landscape development, as well as the broad anthropogenic alterations of the landscape.
