Yes, but given the distance involved when pointing north-east (26 miles) I doubt you'll see much effect unless you have a ground reflection or diffraction close in.
I think @Electron was referring to a south-westerly aim, in an attempt to receive some UHF out of Mt. Wilson. Sadly the predicted UHF conditions coincide with your neighbors local knowledge of the area.
In either case, start by bore-sighting along the boom. If aiming down on to the mesa, point straight at the transmitter antenna. If aiming toward Mt. Wilson, point the antenna at the top of the obstructing ridge. Then fine tune from that starting point, making small adjustments. Every dB of margin gleaned is well worth the effort.
