Any thoughts on this possible geofact?

While I wait for the snow to clear I figured I would ask about this one that is in my curiosity pile from last summer. Found in a gravel pit in Northern MN (with permission). I did not find anything else that looked like an artifact at that location. Almost seems like a crude graver/scraper. For all I know it could be mother nature's handy work and that's why it took a little mid-winter cabin fever to get me around to posting it. I would call the material flint or relatively opaque chert. What gets me second guessing is that there is a portion of the surface that seems a little fresher than the rest along an edge with a bit of a tip on the side of the edge.















Thanks for looking and happy hunting,
Eric

Interesting. It could be a broken base. The thought had crossed my mind. I wasn't sure because part of the surface looks more fresh and so I wasn't sure if just the fresh part was worked while the rest was natural. Thanks for your thoughts rock, I always appreciate it.
