From Boulder, 40 degrees N, where does Orion's Belt rise in the sky on the compass (visible only in Winter at night in the Northern hemisphere) and what altitude is it when it transits the local meridian (North-South arc through the zenith directly above), that is, reaches it's highest point, on any particular night?

Orion's Belt is made up of three stars - Alnitak, Alnilam and Minatak (from left to right) - and is part of the Orion constellation, or 'The Hunter', Orion being a hunter from Greek mythology.

Orion's Belt is on the Celestial Equator, that is has Celestial Latitude of 0 degrees. The Celestial Equator is a projection upwards of the terrestrial Equator (or just 'the Equator') so is directly above the Equator on Earth.

From Boulder in North America, which is at a latitude of 40 degrees North of the Equator, Orion's Belt reaches an altitude at it's meridian (highest point in the sky throughout the night) of 50 degrees, looking due South of the zenith (the zenith is straight upwards from you, opposite from the ground and centre of the Earth). It rises due East of Boulder in the night sky.
