Might be worth a picture

If it was round, I might wonder if it was a Geode, don't know if they're found in more oval/oblong shapes though.

Definitely not a geode. Too many layers in it which indicate sedimentary rock only. No room for an inner chamber.

I found a real pretty rounded multilayered sedimentary rock in the middle of the upper Colorado River which is only about 6-8 inches deep in clear fresh water and maybe 15 ft. across. Rock appears to have been rolling quite a while since it was like an oblong smooth baseball. But about 20 layers of about 1/8 inch or so each. Made the 8 mile RT hike well worth it.

Besides Gold, there are all kinds of Gem stone opportunities in CO.

I always find tons of fool's gold in Colorado. But who knows one of these days I may stumble across the real thing.?️

CO has a ton of potential.

I'd suggest checking the River Banks along the Rivers for such items as suggested in the video.

Definitely Gold in CO if you know what / how to ID the signs.

The Mountains of CO hold a lot of unique Mineral / Gem deposits - one of the better States to look for these items in
