Washed up arrowheads or extremely triangular rocks?

Hi everyone!

Found these in a dry riverbed in North Dakota. I feel like they are way too triangular to not be man-made but the water has smoothed them so much it's hard to tell.

What do you think?

I've labeled the black one #1, and yellow one #2

Hi Curious. Those stones look to be natural water worn stones. One often finds river rocks and stones that look similar to man made artifacts when we look in rivers and streams. Nothing unusual at all. When one finds a genuine artifact in those situations sometimes it may be difficult to discern the difference, but not this time.
