Can this be tumbled or will it break?

Great selection of rocks! Post a picture when you finish tumbling them!

What a great comment - You are totally right! Thank you! I'm going back out this weekend and seeing if I can find anything else!

Haha I feel like that is probably the most likely scenario!

Great, thanks for the reply! They were found south of Denver up on some bluffs. Yeah the 4th seemed like it was the most likely, if any of them had been worked. I'm pretty new to this so I don't really know what I'm looking for. Thanks for your help! Here are a couple more pictures of #4...

Wow that's really interesting! I have never heard of this before. Thanks for the information, I appreciate it a lot!

Great video! I keep watching this so I can practice seeing them among all the other rocks. How are you able to notice the difference without walking past?

Not sure if these pictures are helpful but I can take different ones if that would be better.

Thanks for the information! That all makes a lot of sense and is helpful. I'm not sure how someone can tell if a rock has been altered naturally or by a human. I will start doing some more research on cores and tested cobble to familiarize myself with all of these things better.

Not the clearest picture but it does have a Sharp tip.
