I came across this rock and it just seemed out of place and was wondering if anyone could help identify it.
I am in the Western Upper michigan area.

Two points:
How far is it from a road or an old dirt path i.e. can someone drive to it in a truck?
Upper Michigan was under a huge layer of ice not long ago - glaciers can pick up and move large rocks hundreds of miles.. Is this on a terminal moraine? Or is there a steep rock face uphill and above it?

You have to eliminate human dumping first. The out of place thing is easily handled by: glacial processes or humans. Sometimes rocks go for a ride down a steep rock face, too. And keep rolling for a bit.

I cannot tell if it is a conglomerate or construction waste. You decide. Long range rock identification is nearly impossible, sometimes up close is still tough to do, as well. Note: it has not been there terribly long - no lichens. So you can guess what I think. Compare it with the rock in the background.

Hi there! I'm not an expert in geology, but I can try to help identify your rock. Can you provide any more information or a picture of the rock? That would make it easier for me to assist you. Also, have you checked any online resources or reached out to a local geology club or university for assistance? They may have more knowledge and resources to help identify your rock. Good luck!
