  Description:
    Abstract:
      Hand-held magnetometer and sample magnetic susceptibility
      measurements used to help interpret complex patterns in the magnetic
      anomaly of this area.
    Purpose:
      Provide ground-truth information for magnetic anomaly studies
      designed to determine the cause of low-amplitude aeromagnetic
      anomalies over Quaternary alluvial deposits in the study area.
