Abstract
Geophysical surveys utilize spatial data to analyze geophysical signals from underneath the surface. Magnetic and gravitational fields allow information about internal structures like subterranean bodies to be collected without destructive practices that would damage geologic settings and ruin future in situ measurements and samples. The Quarry Gardens at Schuyler is a popular tourist attraction that educates visitors about the history and uses of soapstone while showcasing the local area's unique history with soapstone mining. This vast history has left its mark on the land in the form of two quarries: large holes gouged into the Earth that can be seen from satellite imagery. Light Detection and Ranging (LiDAR) topographic data was used in tandem with geographic information system, computer aided design, and additive manufacturing programs to create three-dimensional models to allow visitors to better visualize underlying geologic bodies and view the long-lasting effects of soapstone mining. In Roseland, a new chestnut orchard was planted near Zion Hill Church overtop a northeast trending dike. Since nelsonite is magnetic, a magnetometer can be used to predict the size and shape of the dike without disrupting the growing process of the trees and destroying the land. Geophysical surveys allow for the collection and manipulation of physical and digital data that allows geologists to make accurate conclusions using new technology. Both projects aim to turn quantitative data into three-dimensional models to easily visualize geologic bodies from the past and present.
