Geologic Map of Quaternary and Upper Tertiary Deposits, Tucson 1° x 2° Quadrangle, Arizona
The Tucson 1 ° X 2.0 quadrangle exhibits a wide variety of basin landforms and late Cenozoic surficial geologic deposits. Several factors contribute to this diversity. The Tucson quadrangle spans the transition between the relatively low ranges and typically undissected basins of south-central Arizona and the higher ranges and typically dissected basins of southeastern Arizona.
