Rock surveyors take to the skies
The geological foundations of the South West are being mapped in the first aerial survey in the region for about 50 years.
Low-flying aircraft are taking images of Cornwall, Devon and parts of Somerset.
Dr Andy Howard, of the British Geological Survey, said the results could have an impact on everything from the local economy to health policy.
The new study of rocks beneath the surface could tell where tin could still be mined, which fields were richest for farming, and whether there was a public health risk from the radioactive gas radon, he said.
