Mapping is a means of documenting, synthesizing and portraying scientific observations and interpretations of geologic deposits that record important episodes and timing of geologic activity. Our project is based primarily on surficial geologic mapping and regional-scale geologic maps but, will also conduct bedrock mapping and related structural studies. Our workflow involves characterizing and portraying a complex stratigraphic record at intermediate scale (e.g., 1:100,000). This process includes new geologic mapping in addition to compilation and refinement of existing maps, using a common stratigraphic nomenclature. These efforts are rely on modern GIS technology." }, { "@type": "TextObject", "text": "The lower Colorado River study area includes one of the world\u2019s most iconic landscapes (Grand Canyon) and embodies a water resource that is essential to the water and electric power requirements of more than 40 Million people in the southwestern United States." }, { "@type": "TextObject", "text": "This is a comprehensive scientific investigation of the geologic history and framework of the lower Colorado River.
