This material just came out of the tumbler and its left as a whole.. Looks like a throw away, but something drew me towards this rock... Its out of the Yellowstone River in Montana..

Any opinions on what this material might be? It does have a bit of agate in it.... I really don't want to cut it either...

Looks very similar some some Montana material I posted here last summer for an ID. What I have will change color when heated. Gets a lot lighter. Knapps well.
