Mount Boyce is a hill standing approximately 1,093 metres (3,586 ft) AMSL, situated as one of the highest points on a plateau within the Explorer Range, part of the Blue Mountains Range which is a spur off the Great Dividing Range. Mount Boyce is located 2 kilometres (1.2 mi) north of Blackheath, in New South Wales, Australia.
The area is called "Blue Mountains" based on the fact that when atmospheric temperature rise, the essential oil of various eucalyptus species evaporates and disperse in the air, then visible blue spectrum of sunlight propagates more than other colours. Therefore, the reflected landscape from mountains seems bluish by human eyes.
