GPR INVESTIGATION LOCATES A MISSING REDOUBT SECTION AT HISTORIC HUGUENOT ST., NEW PALTZ, NY
Grids of 5 x 5 m were established and investigated by half-meter transects using a Sensors and Software Noggin GPR with a 250 MHz antenna. Software-generated 3D models show a known alluvial gravel layer dipping from about 1.5 m depth in the northwest to 2.0 m in the southeast in our eastern-most grid. A north-south linear target intersects an east-west target forming a clear corner at about 0.5 m depth on the northeast edge of the grid, and was chosen as a point for excavation during SUNY New Paltz’s summer 2018 Archaeological Field School.
The excavation of units 251, 252, and 253 on a north/south axis located a north/south linear trench at the corner of the redoubt. The trench, and the enigmatic post-molds at the base of it, were similar to the eastern wall of the redoubt. Finds from inside the trench include 17th-century Dutch majolica, small red locally-made Dutch brick and hand wrought iron nails from the 17th century.
