How do i cut 6x6 timbers for retaining wall

Not sure what the best way to do this is.
Im building a wall where the ends will overlap like in the picture.
This wall is 90 degrees, where mine will be about 120 degrees at the corner.
How would you cut them for a smooth look?

Use a Swanson Square and set the angle at 15 degrees on top and bottom. Straight line the sides and cut with a circle saw across the two angles and chase the core with a reciprocating saw since the circle saw won't cut all the way through.

Larry is describing a miter joint, but if you want the look of every other row overlapping (and you would probably need to do it that way for strength so that they would interlock, each row could be fastened one row to the next) You would cut a 30 angle off the square end of each piece, which would really be putting a 120 angle on the end of each piece. Then you would just alternate sides... one being long forming the corner angle, with the other butting up to it, with a corresponding 30 angle. Then the next row you would do the same thing but alternate sides.

Brant is right. I was thinking of taking half off each run, but you need to make a 30 degree angle on each end rather than 15. My bad.
