This similar view of Euler (compare to Figure 137 , taken with the Apollo 17 mapping camera, is included because it shows even more clearly the relationship between the ejecta from Euler and the surrounding mare lavas. The youngest lava flows in the Imbrium basin (Schaber, 1973) have overlapped and embayed the Euler ejecta from the north, west, and south-especially at places marked by arrows. The long sinuous rifle south of Euler is associated with the late stage lava flooding. The clusters of large secondary craters (S) are from Copernicus, 400 km to the southwest. In the southeast part of the picture some of these secondary craters and their associated ray deposits overlie the mare lavas. The following sequence of events therefore took place: (1) the Euler impact, (2) flooding by lava, and (3) the impact of material ejected from Copernicus. -G.G.S.
