This was on another thread in another area but I didn't get any answers as to what I am looking at in the pic, so... This is inside a soffit/dropped ceiling between a 1st floor bath and the second floor. Ceiling is about 6 inches lower than rest of house (bath ceiling 7-6 and rest of house is 8-0 ceilings). It's looking toward an exterior wall about 3 feet from the camera. I'm mostly trying to I.D. the rim joist. The rim joist is the second joist in back (you can barely see its bottom edge), the question marked wood is the top plate, sound right? Thanks!
