The cone was formed by fire-fountaining from two vents that produced an oval double cone. The lower northern cone and its crater is partly covered by the younger and larger southern cone and crater. Lava poured out from around the base of the cones and flowed north and west down shallow valleys to now underlie Stoddard Rd and parts of the SW Motorway nearly as far west as the Westmere tunnel mouth.
The main crater of the larger southern cone was excavated out and a large concrete reservoir buried in it in 1961-1962. The upper carpark is now located on top of the reservoir.
In 1928 George Winstone donated Mt Roskill to Mt Roskill Borough Council to become a Recreation Reserve.

Mt Roskill is the second most western volcano in Auckland - can you see and name the western-most?
On the crest of the larger cone are pits - how were they formed?
Can you see the terracing down the outer slopes what were they built for and by whom?
What were the cones made of - you can see some of this frothy rock in the cutting beside the access road up the cone.
