just curious, something I found Options

[jay]

Hello,
I joined this forum to see what I found today in Elizabeth, CO. I was walking around a job site today and found what I think is petrified wood. The other guys there said I was crazy, so I kept walking around and found a rather symmetrical rock. This may be common but I thought it was neat.
The other rocks seemed to have some sort of crystallization, could I cut these open or just a common rock to the wonderful rocky mountains?

Welcome to the forums Jay!
The first rock looks like it its petrified wood that has been replaced with Chalcedony (a form of Quartz). It has very beautiful color!
The second rock looks like some common river rock here in Denver. I want to say Dolomite but I'm not sure if that's correct.
#3 and #4 appear to be Quartz with Pink Feldspar.
The last rock appears to be Quartz.
Some of those rocks with crystals you mentioned may lend more clues to the types of rock you are finding.
Nice Finds!
