I need to hike up and get a pic but, just wonder if anyone would know. I found a odd granite bolder in the bottom of a dry river. That stuck out from all the rest it had a chunk missing the size of a basket ball and all around that spot there was about 6 inches of rock that looked heated to fuse. And good sized cracks radiating from it. We tried scraping around the bottom and thought we could just make out rust traces in a little mud at the bottom. The water would have flowed almost right over it so we wonder if it rusted away or the only other source of iron around was old mining junk. So rust could have been there from that washing down...hard to say... anyone thoughts ,ideas, comments?

I think pyrite makes some water appear "rusty." ??
