R1: Albulfeda has a flat floor with a small central crater. Whereas most of the walls look thick and terraced, the W wall looks steep/ridged.
R2: The Catena Albufeda begins at Albufeda's S-SW, travels just north of Almanon, then curves SE below Tacitus to join the northern Rupes Altai.

C1: Some craters on the north wall of Albufeda are smaller and shallower than others.
C2: I could make out at least 5 secondary craters on the N wall.
C3: 
Think I saw the 4 craterlets that begin the Catena on the south wall of Albulfeda when the seeing improved. Most were small and in the crater wall.
