  1. GPR applied to San Marcos Pueblo, NM, Archaeological Site Laura Russon

  2. Outline: • What is GPR? • Dewow Filtering • Midden 2 site • GPR scatter and reflection • Anomaly east of Mission Complex

  3. K1 K2 Ground Penetrating Radar A.P. Annan, GPR notes

  4. Dewow Filtering A.P. Annan, GPR notes

  5. Average Amplitude Time Slice: 0 to 9.94 ns Midden 2 Y position in meters N X position in meters µV

  6. Average Amplitude Time Slice: 9.94 to 19.87 ns Midden 2 Y position in meters N X position in meters µV

  7. Average Amplitude Time Slice: 19.87 to 29.81 ns Line 1 Midden 2 Line 2 Y position in meters N X position in meters µV
