It is part of the Auckland volcanic field. The volcano erupted around 24,000 years ago, forming a large crater and tuff ring about 500 meters wide. The prominent tuff ring is still clearly visible extending in an arc south of Sunderlands Road. Two much smaller craters were formed to the north west of the main cone. The smaller lies buried under Pigeon Mountain Road outside number 18, and the other forms Heights Park, a private reserve for the owners of 29–41 Pigeon Mountain Road and 14–36 Prince Regent Drive and 33–39 Tyrian Close.
