Pretty easy feature to locate. I set out only planning to sketch Sinus Iridum, but noticed that both Promontorium Heraclides and Laplace sat on either side, this allowed me to get a three for one!

Heraclides is the promontory to the west pointing east. Laplace is the promontory to the north pointing south. Laplace had a very noticable triangular shadow stretching to the west.

The two lonely craters in the low lands to the south east are Helicon and Le Verrier. I included them in the sketch because they looked cool, but they are not on my lunar list.

The terminator was at the north-western border of the sketch.

[1] Sinus Iridum (ID)
