No wonder I was tired! Update.

My family are (were?) cavers. I am familiar with the caves of NSW, as we used to go away often to cave. My parents were members of the Sydney Speleological Society and I typed the SSS monthly magazine for a year or two in the seventies. Ah, those were the days!

I found some old newspapers which I hadn't read, they'd been sitting waiting to be used as a mulch base if I could ever afford some straw mulch. Well, that's not happened, so I dumped them in the bin (straw or other mulch was dear as poison in the drought as it was used for emergency feed and the price hasn't come down much).

The magazines fell out of The Weekend Australian so I thought I'd read them. So, I put them in chronological order (as you do), and read oldest to most recentl.

The first one was from August this year. There is a short article in it on the deepest gorge in Australia.

The photo looks familiar. Oh my, it's a place I have walked... near the Shoalhaven River. There are caves there.

The Deepest Gorge, no wonder I was so tired when I walked it as a very young teenager!

Here's the link, the  photos are spectacular. If it's paywall protected you can google the name and author of it and sneak in that way.

Many years ago there was a fight to save the gorge, there is a limestone quarry there on the northern side of the gorge, toward the Shoalhaven river. There was concern that it would be an eyesore in such a place and would destroy caves in the area. I don't know what it looks like now, but of the linked photos above one is dated 23 months ago.

UPDATE:
Here's a picture of the Gorge. I've walked through it, down and up the other side.
