A bedrock map generally includes rock descriptions, age relationships (stratigraphic sequence), and major and minor structural data used to portray a three dimensional model of the rock on a two dimensional topographic base map.Bedrock Survey and MappingThompsonPeterConradDianeThompsonThelmaBeckerLaurenceGaleMarjoriegeologygeomorphologymappingbedrockBedrock Geologic Map of Vermont1993-06-012011-12-31A bedrock map generally includes rock descriptions, age relationships (stratigraphic sequence), and major and minor structural data used to portray a three-dimensional model of the rock on a two-dimensional topographic base map.
