Interpreting Geology of Ashley Schiff Park Preserve with New High-Resolution Digital Elevation Model

The objective of this study was to interpret the geomorphic features developed by glaciers at Ashley Schiff Park Preserve and to study whether south part of Ashley Schiff Park Preserve is Hummocky terrain or whether it is just a continuation of folding and faulting process. This required creating a new high-resolution digital elevation model (DEM) based on 2-foot contour interval with 1-meter grid cell size by using GIS software ArcGIS v9.0 with its 3D Analyst extension. Ground Penetrating Radar (GPR) radargram of 100MHz was also used to examine the subsurface structural trends and patterns. Glacial features in north part of Preserve are developed from proglacial thrusting whereas it is evident from new digital elevation model and GPR radargram that the southern part of the preserve is more likely a hummocky terrain.
