Tocumwal blowhole

Where I grew up a blowhole was where ocean waves rushed in to a cave and blew out through a hole in the ceiling of the cave. So I was intrigued when I saw that there was a blowhole at Tocumwal near the Murray river, a long was from the sea. We went to have a look of course.

It was a bit tricky to find because there aren't any signposts anywhere. And the granite outcrop is a minor bump on the horizon, just a few metres above the flat farmland that surrounds it.

The information board at the entrance calls are the area Tocumwal Rocks and describes the several deep holes in the top of the granite mound and Aboriginal legends associated with the area. They believe that the holes are connected to the Murray River about ten kilometres away, via a tunnel through which the spirit travels. It would have been a sacred place and I can see why.

There is a photo on the information board showing the deeper of the two holes when it is nearly dry.

When we visited the holes there was water overflowing from the hole and trickling down the granite slope, supporting a variety of plants. Even in times of drought and low water in the river, the hole will bubble and overflow with water, like a fresh water spring.

So, we didn't see any 'blowing' but it was a fascinating area to visit.

Hi Lorraine, thanks for posting this - it's very interesting. I'm familiar with some of the granite outcrops on Eyre Peninsula in SA, but had no idea there was one like this near Tocumwal. Tocumwal has always been a place I've just passed through, so I'm glad you're drawing attention to some of its interesting features. Cheers, Paula

This reminds me of the "Bubblers" off the Oodnadatta Track, very interesting.
