Name these rocks

Could someone identify these rocks I collected at Lake Luzerne yesterday?

A bit too blurry for me, but perhaps that's just my eyes.

Could be granite, but the pics are way too blurry to tell.

Yeah, it's a bit blurry because I took the picture off of my webcam so I apologize for the picture quality.

It's particularly the second picture I think looks a bit like granite, but I can't really tell. If it is, I'd think it would look like this: http://www.lewis-clark.org/media/New...ay-hyndman.jpg

I got an overhead shot of it and reduced the brightness. I hope this helps.

The picture won't display.

I added the picture onto the original website I posted. It's the third picture down.

Let me know if you have any problems accessing it.

Since the books in the background are in focus and the rock isn't maybe if you take a step back, you can get a sharp picture of the rock. Just a thought.

Looks like a possible Quartz Monzonite to me. Seems to be a fair bit of k-feldspar and lacking in Qtz. That could just be the lighting in the photo however.
