When one is halfway up on one side, the other is halfway up on the other side. Crux moves around the south celestial pole in a clockwise direction, while the Big Dipper moves around the north pole counterclockwise. Now it is entirely invisible north of Texas, or 35 degrees north latitude. Due to the same precessional motion, coincidentally, the Southern Cross was last seen from the latitude of Jerusalem in the century when Christ was crucified.
