Crystal Skull. Indiana must have lost it the last time he was through there.

Looks like quartz or agate to me

In that case, a piece of quartz. In Canada they call them diamonds. Take it there.

I don't know much about rocks, but my first thought was also quartz or agate.

Very cool.that is what i went huntung for. And this other one. Any ideas? The top one.

definitely quartzite. See the circular/semi-circular fracture patterns on and beneath the surface? That's conchoidal fracturing which you'll see with quartz (and many other minerals as well - conchoids doesn't always = quartz). I'm guessing you found this somewhere there used to be glaciers, looks like it's been rolled around and beat up by glacial transportation.

Was semi burried in the sand/gravel bank of the yellowstone river.

It looks like a chunk of quartz. If you are looking for agates on the Yellowstone, they will be darker than that. The surface of them, because they are stream rounded will have little fingernail shaped chips, very tiny and they will look cloudy. Sometimes they will have fresh breaks where you can tell for sure that it is agate. I'm jealous, I want to go with you haha! Other piece looks kind of like pet wood, but it's hard to tell from you pic.
