R1: Crater Triesnecker is just west of the rille system. It has a small central elongated peak. It is circular in shape with a slight bulge on its west side that appeared brighter than the crater floor.
R2:  Rimae Triesnecker that runs north and south of the crater Trieesnecker appears to be curved.
R3: The eroded crater Rhaeticus is south of Triesnecker; its west rim is virtually non-existent. There is a line of 3 or 4 small craters towards the NE. In Sinus Medii, zero degrees latitude was found just south of the crater Bruce. 

C1: Surveyor 4 & 6 landed near Bruce on the seemingly smooth Sinus Medii floor. Murchison, Bruce, Pallas and Blagg were located. Bruce and Blagg were located in Sinus Medii. Murchison had an open rim in the south and eroded walls in the NE. Pallas had a central peak.
