Lava Rocks, Iron Slag, Meteorites or something else?

[KJW]

I started a thread about this on the Meteorite page. I am putting a link here in case anyone might recognize what I have. I found them in a creek and I think there are more of them. A magnet will stick to them in spots but some spots it will not stick. I was thinking it looks closest to Iron slag but I was wondering if a magnet would stick anywhere on an Iron slag or do magnets sometimes not stick to Iron slag? You can see pictures if you look at the link below.

Thanks for any help in advance. Kris

Sorry, I don't know what they are but from the rough shape I would guess that they didn't travel far in the stream. A search up stream might give you the source and from that the answer you seek.
