The bright ray crater
at far left is Anaxagoras --ignore it.
Contemporary observational work is represented by analyses of the ray crater
Proclus and of shallow linear features found near Rupes Recta and in other parts of the lunar surface.
When asked if he had explored any craters, Duke responded, "Neither John [Young] nor I ventured to the bottom of a crater such as Plum or North Ray crater
With a diameter of 31 km, this young, rarely noticed ray crater

So from the bright highlands to South Ray crater
, you can observe 4.
For example, look at Copernicus, the second most conspicuous ray crater
If the incoming object had approached from the opposite direction, the rays would pass over the lunar limb and would be harder to see; we might not realize Thales was a ray crater

At first glance it looks like an ordinary small ray crater
, despite being a mere 40 years old.
