Is it an irregular elevation, or a shallow depression? (trompe l'oeil effect near Doppelmayer J)


Nomenclature

Johan Gabriel Doppelmayer (1671 –12/1/1750) was a German mathematician, astronomer, and cartographer. He completed his studies in 1698 with a dissertation on the Sun.

Doppelmayer pyroclastics

The Doppelmayer pyroclastics are briefly mentioned in the 21st Century Atlas of the Moon (C.A.Wood/ M.J.S.Collins) on page 82 (the southwest quadrant of the Full Moon) and on page 58 (photograph of the Doppelmayer rilles).
