This is one of my favorite regions on the moon, and it is also where I started out doing moon observations. I have done several sketches of the region, but so far no detailed studies of Aristarchos. The former is rich in detail and very bright, especially compared to neighboring Herodotos. Schröter’s Valley is a sinuous rille, that is believed to have been one of the major lava sources of Oceanus Procellarum. To the right is the moon’s thinnest mountain chain, Montes Agricola.
