I just got back from Michigan's U.P. where I found some fun rocks in Lake Superior. One of them is a rock with a translucent orange part. the rock is about golf ball sized. Any idea what it is? More pictures: farm9.staticflickr.com/8158/7172920741_fd3ea67c3a.jpgI want to tumble it, but there are some tiny holes in part of it. Should I try to grind the holes out first, or just throw it in the tumbler? Other than the holes, it's pretty smooth. Thanks, Rob
