      USCS Classifications
      Refers to the Army Corps of Engineers Unified Soils Classification System. Class types
      are defined primarily by grain size, sorting and percent of material passing the #200 sieve.
      Classification of materials on the core logs based on visual field examinations are identified on
      the core logs under the Classification of Materials Description. Classifications based on
      laboratory sieve analyses are identified on the core logs in the Legend and under Remarks.
