This seems like the best place to post this. I found this interesting rock while out rock/geode hunting in the Cascade mountains last summer. Found it in a small creek. The green color was what initially caught my attention. While it was underwater, and the way the sunlight was hitting it made it look much more vibrant. It's very slightly magnetic on the rusty brown areas. Those are a couple very strong little neodymium magnets that just barely manage to hold on. Anybody with more geology knowledge than me have any info or insight?
