Notes:

Regional dark mantle deposits (DMR) have areas greater than 1,000 km^2; localized dark mantle deposits (LDMD) have areas less than 1,000 km^2. Position of Montes Harbinger DMR is corrected from Gaddis.

Where Head or Gaddis designations are ambiguous, consult LAC color-coded charts. Semi-major axis size based on rough Rükl chart take-offs; region designation from Gaddis 1985 except for Southern Sinus Aestuum Dark Mantle Region - West, which is in Head 1976. For distribution maps, see Figure 9 in Gaddis 1985 and Figure 2 in Head 1976.
