I went on a hike at Goldie Track in the Waitakeres in West Auckland. There were rocks of all formation. One rock looked very smooth, but when I brushed my knee against it, it scraped my skin, and I still have a dark scar to show for it.
And if you go to my last post, you will see some volcanic rocks.

I learn when you go for a long track, and you are not fit, you cannot be QUICK. I tried to climb up a rock quickly, and my knee got scrapped.
