That portion of the coast of Antarctica lying W of Ronne Ice Shelf between Cape Adams and Cape Zumberge. Discovered by the RARE, 1947-48, under Ronne, who named this coast for Capt. Howard T. Orville, USN, Head of the Naval Aerological Service, who was largely responsible for formulating the RARE meteorological program. The name Orville Coast is considered a more useful reference than "Orville Escarpment," the name originally applied for this area.
