Mare Crisium Illuminated on the Young Moon

Mare Crisium is that interesting isolated sea on the northeastern side of the visible lunar surface. Not long before beginning the sketch, it became fully illuminated.

The Nectarian Period impact event that formed this feature occurred more than 3.8 billion years ago. The mare portion of the basin is about 500 kilometers across. In the grazing sunlight on the floor, wrinkled ridges were visible. Also on the western floor craters Picard (24 km.), Peirce (19 km.) and Swift (11km.) stood out in the low light. I could see the lighter gray bench lava that partly buried craters here such as Yerkes (37 km.). Tall flat top mountains (massifs) beyond the shore stand at 2-5 kilometers above the sea. Both promontoria Lavinium and Olivium stood out clearly in very brief moments.

  1. Frank, I just want to echo what Dale said, each sketch you do seems to increase in detail and beauty. Thanks so much for sharing these with us!
