GPR on a High Mountain Lake, Colorado, USA
Many GPR reflection profiles were collected using a canoe on a freshwater lake in the Rocky Mountains. Excellent radar wave penetration was measured, using both 270 and 400 MHz antennas. Reflection traces were placed into space using GPS and individual profiles were interpreted, with the lake bottom and other reflections digitized for three-dimensional mapping. It was found that the lake was composed of more than six sub-basins, which were bounded by glacial moraines and large bedrock slump blocks. Each basin contained a different sediment package with a unique depositional history. One small basin was chosen for coring, and a buried…

Salinas Cow Manure Project
This is a fun paper that shows how even some of the worst conditions for GPR, can prove to be important with results that the client said were important. One of the very worst GPR projects of all time with collection in the rain and the ground wet cow manure.

GPR mapping to reconstruct a Late Classic Period Compound Wall, Chichen Itza, Mexico
by Lawrence Conyers and Denisse Argote | Integrating a lidar relief map with GPR subsurface mapping, accompanied by locating known and inferred surface structures allowed for the reconstruction of a Late Classic Period walled compound. It was found that this enclosure is not perfectly rectangular, was partially dismanteled in the past, added on to in some places, and in some areas almost completely destroyed during the construction evolution of this city. The compound contained the Casa Colorada as its predominant temple within its walls, but also other structures of unknown function. In Post Classic time the compound walls were used…
