The northwestern part of this feature is located to the east-southeast of the crater Rocca, and is contained within the rim of the satellite crater Rocca A. The other part lies to the southeast of the first, and forms an elongated, irregular patch that extends generally in a north-south direction. The southern tip lies about one crater diameter to the northwest of the flooded crater Crüger. Crater counts of this feature yield an age of 3.50 Gyr for the basalt, placing its formation in the Imbrian era.[1]
