I Wanna Rock!

We went to Glencoe, OK early this morning to get some rocks a lady was giving away.  Some were pretty interesting.  I managed to get three rose rocks (Oklahoma's state rock) that were a bit eroded, but for free, I couldn't complain.  Pictures are below of the rose rocks and others I got.  I might go jasper hunting sometime soon.  We got directions to some public land where anyone can go pick up pieces of jasper.

Different background, but same rocks

Could somebody identify this, please?

Variety of rocks and shapes

Different crystals in this rock

I'd never really paid attention to the inside of this type of rock, which I always considered to be river rock.
