Colorado High Rock

Colorado High Rock

I found this rock at 10,500 ft in the Rocky Mountains of Colorado. It is non magnetic and it has no effect on my metal detector. Any help identifying this rock would be greatly appreciated.

Hey Wade,

Thanks for posting your find here. Do you remember where in Colorado's mountains you found this? To me it looks like banded ironstone but if it was it should be magnetic. The red looks like it could be jasper. You could do a scratch test for hardness. Jasper is a 7 on the mohs scale. See below:
