“We saw some fluctuations in the data while we were in the field, but we cannot say with any certainty what those might be until we process the data,” Kangas said. “I don’t know any place we would scan and not see fluctuations, so this doesn’t necessarily mean there is anything unusual underground. Even if we do see anomalies that might indicate something is underground, we can never say with 100 percent certainty what it is with just the GPR data, it would need to be ground truthed.”
