Can you identify this mysteriously green rock?

I usually pick up interesting rocks when I go fishing. This one
was found in a river in Colorado. It is really
green and very smooth (is was in the river). Anyone know what this is? $2.5 million worth of rare jade? Radioactive "Homerite"? Or, just a green rock?
