Archaic Shell Mounds
Linked via "ground-penetrating radar (GPR)"
Modern archaeological understanding of Archaic Shell Mounds is complicated by extensive post-depositional disturbance, primarily from the historical quarrying of shell for lime production and road ballast, termed "shell mining."
Many extant mounds are now protected, often incorporated into state or national park systems. Ongoing remote sensing investigations, particularly [ground-penetrating radar (GPR)]… -

Paleoseismic Trenching
Linked via "Ground Penetrating Radar (GPR)"
Methodology and Excavation
The process begins with geophysical surveys, such as Ground Penetrating Radar (GPR) or magnetometry, to locate the subsurface expression of the fault structure, often referred to as the shear zone terminus. Once the optimal location is identified, trenches are excavated, typically measuring between 10 and 50 meters in length, 3 to 6 meters deep, and 1 to 2 meters wide. These dimensions are standardized to… -
Quaternary Alluvium
Linked via "ground-penetrating radar (GPR)"
Geophysical Signatures
The electrical resistivity of Quaternary alluvium is notably lower than underlying bedrock, making it an excellent target for ground-penetrating radar (GPR) and electrical resistivity tomography (ERT). The reduced resistivity is commonly attributed to the high interstitial water content and the presence of dissolved ionic compounds derived from the decay of e…
