I found this rockhounding yesterday in Wyoming at Glendo Reservoir north of Wheatland. The second photo is a close-up of the first.

It looks like an oolite with chalcedony, calcite or similar ooids (perhaps as replacement, since I don't see any banding/layering). As Wyoming was once a shallow inland sea and later had periods with glacial lakes, conditions existed where oolite could form. Pretty colors!

That's really a freezer burned pork chop right?  You're just seeing if we'll catch on..\    :azn:

Just wanted to add a note for identification help, one thing on corals is that the polyps will have similar sizes to each other and not be a mix of large and small in the same piece.  I think the pork chop will need to get smothered in Sauerkraut to help with the freezer burn.

I go along with oolite. All the ones I've had are brown though.
