Welcome to My Favourite Local Volcano. To the east of GZ you'll see a substantial hill. It's the dormant volcano: Mount Cottrell. The cache is not far off the road..
The cache contains a log, a pen and a pencil, a First To Find card and some swag. Please remember the geocaching rule: Only take swag if you swap it for something of equal or greater value. Please return the cache to its hiding place as you found it. If there are problems please contact me and I'll do maintenance.
With a volume of 2L this cache is classified as a Regular (M)* size.
There is safe, side of the road parking next to GZ, but whatever you do, don't drive into the ditch!
Now some information for volcano fans: Mount Cottrell is a volcanic cone formed by the radial eruption of numerous lava tongues. The flows are symmetrically distributed around the vent producing a cone of geometric shape. Although achieving a height of only some 200 metres, the cone is of considerable bulk with flows extending almost 10 km to the south. The massive nature of this basalt cone is not readily appreciated when viewed from close quarters, but is readily apparent when seen from a distant point such as the You Yangs. There are two aspects to the significance of the site, namely the specific nature of the bluff and crater at the summit, and the extent of the radial flows. The cone is the most massive of the Werribee Plains volcanoes and gave rise to a number of distinct lava flows. The basalt rim is of particular interest as it has similarities to the cappings on the volcanoes of the Gisborne area, although Mount Cottrell is a much younger eruption point than these. The flows from this point towards the west influenced the course of the Werribee River and may have dammed the stream near the junction of the Djerriwarrh Creek.
