A large scoria cone with a visible crater on the South Eastern side, this eruption point is just North of the Western Fwy. There are rocky outcrops on the Northern flank.

This eruption point is a low heavily eroded scora cone with a shallow crater that is breached on it's Western edge.

Composite scoria cone with lava

This is a complex of three scoria cones and a possible maar.  From a distance it appears as a group of prominent hills between the You Yangs and the Brisbane Ranges.  Mount Rd runs between the most northwest cone and the maar and is a good way to observe many of the features. Alternatively, you can visit Del Rios vineyard on the southern slopes of the main cone and after a drink at the cafe ask about access.  The Lovely Banks monocline runs south from here to Geelong as a linear bank.  It is not known if this feature is related to the volcanoes.

Stockyard Hill is maar-like, but has associated lava flows and scoria desposits and it likely to have a complex eruption history.The Stockyard Hill Windfarm project has produced some interesting documentation about this area, and photos and information about Stockyard Hill can be found
