Subject: Lade & Godin (Lunar Impact Craters)
Sketch: Black ink stippled on white cartridge paper

Comments: Lade (56 km, across, named after Heinrich E. von Lade, a German banker and amateur astronomer of the 19th century) is the basalt-flooded remains of a ruined impact crater. The south wall has been completely destroyed and the eastern rim is low, thin, and full of gaps. The western wall appears to be a bit more substantial. The crater has a distinctive hexagonal shape. Just north of Lade is a plateau (24 km across) designated Lade B. This crater, like a miniature version of Wargentin, has been completely filled to the rim with lava.

Godin (35 km, named after Louis Godin, the 18th-Century mathematician from France), in contrast with Lade, is a sharp, well-formed impact crater with terraced walls and a small central peak (hidden in shadows in the sketch, it was just becoming visible as I finished up). The crater is not perfectly circular, however; it is wider at the southern end and narrow at the northern end. An illuminated ridge outside the western wall gave me the impression of a partially opened heart-shaped locket. Godin (along with Agrippa, a crater to the north) is surrounded by an interesting arrangement of hills and mountains. I particularly enjoyed sketching the peaks west of the crater.
