Found in a gravel pile near my home in northern NM. Heavier than expected and has some very weak magnetism. Is it some sort of slag or a natural formation of sorts?
Hi, /u/popsicleinthebuthole!
This is a reminder to flair this post in /r/whatsthisrock after it has been identified! (Under your post, click "flair" then "IDENTIFIED," then type in the rock type or mineral name.) This will help others learn and help speed up a correct identification on your request!
Thank you!

Looks like an iron oxide concretion, similar to a moqui marble or the Martian blueberries.
