Although I am brand new here, I already have a question. Unfortunately, no photos yet, but I will describe the best I can.
I see these things at Lake Pueblo on a regular basis. In the light grey sediment/shale, where i find seashell fossils, I also see small balls (3/4" or so) that look like iron. They have a color like rusted iron. Rough on the outside. Almost perfectly spherical. They discolor the rock that holds it (slightly) around the ball. I have not checked for magnetic characteristics. I cut one open and it seems to have a starburst type pattern on the inside. I heard somewhere that when hot metal (iron) is cooled quickly (possibly when this area was a sea), it may leave that pattern. I also wondered if they are round because they were molten and hit the water, cooled quickly, and sank to the bottom, to the sediment. Does anyone have a general idea of what they may be? I have my uneducated theories...So, if anyone can shed light, it's been driving me nuts. Thanks!
