my rocks collection

Fascinating :o)

I wonder what a geologist would make of these specimens, it would be interesting to know how they were formed.

The one on the top looks like an ancient plumbing pipe. It reminds me of the terra cotta pipes that I saw in Pompeii.

These will look good planted up with succulants, sempervivums or cactus.

That's a great idea Treesandthings :)

Very interesting rocks. The one at the back looks like a petrified tree root or branch. So intriguing. I wonder if they are formed from ancient lava flow?

I have a great many of various rocks ,i will take some pictures and put it on GOY.
