Current Riddle

I am composed of minerals.
Quartz makes me up.
With a hardness so hard,
not even a knife can cut.

I form in layers
that are compressed over time.
You can find me in the creek bed,
hidden amongst the lime.

I break with a fracture
that's uneven you see.
So, please walk. Don't run!
You might scrape a knee.


Tyler's arrowhead is made of this!
