These controlling factors fall into three broad categories: 1) bedrock controls - parent rock characteristics; 2) physical controls - faults, paleotopography, etc.; and 3) chemical controls.enMinnesota River ValleyBedrockPaleotopographyGeochemicalLate CretaceousNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
