jinmon Posted March 18, 2019 Share Posted March 18, 2019 Saw some neato rocks in the Cajon Pass Area by the train tracks. I suspect this is a byproduct of the railroad somehow but wasn’t sure what they could be so I figured I’d share and someone smart would recognize it! As you can see, the first rock is chocolate-glazed. The third pic is of a clear sugar-glazed rock - much harder to see the glaze because it’s clear, just take my word for it. What could’ve caused this? I suspect heat was involved but past that I’m clueless. ? Thanks in advance! Link to comment Share on other sites More sharing options...
Steve Herschbach Posted March 18, 2019 Share Posted March 18, 2019 Looks like slag from a smelter. Not uncommon near railroad tracks transporting material to and from smelting operations. Link to comment Share on other sites More sharing options...
