Sunday 21st June:
The Tocumwal Blowhole, is a large hole in granite, well actually two separate holes of different depths, that are alleged to lead all the way to the Murray River, some 10 kilometres.
The Blowhole is said to be sacred to the Ulupna and Bangaragn Aboriginal Tribes. In times of drought and low water in the river, the hole will bubble and overflow with water, like a fresh water spring. There are two holes here of different depths. The larger hole is said to be about 5m deep. There is a deeper narrower hole which is rumoured to be about 20 to 25m deep. There is a hollowness of sound on the south side of the larger hole that could be a cavern.
The Granite beds the Tocumwal Blowhole is formed in were laid down
in the Silurian Peroid around 416 to 443 million years ago
On the way back from the Blowhole we stopped and took a couple of photos for the WW2 hangers that still remain from when Tocumwal was an airbase back in WW2.
